Response to Arguments
(Argument 1) Applicant has argued in Remarks Pg.7:

(Response 1) The claim does not disclose any mechanism to perform iteratively altering. This is either a mental step where the (expert) user decides how the altering needs to happen such that productivity index matches the known reservoir pressure (Step 2A Prong 1) or is an idea of a solution (Step 2A Prong2) where any input is well test data & well simulation and output (solution) is adjusted per-lateral PI, with no steps/mechanism to achieve the solution claimed. One way to overcome this rejection is for the applicant to claim how the iteration is performed, i.e. which is not a mental step (based on some algorithm/steps/mechanism). As for physical valve adjustment aspect there is no nexus between based on the predicted multilateral well production parameters, as indicated in the updated rejection and therefore remains a field of use/idea of solution.
(Argument 2) Applicant has argued in Remarks Pg.7-8:

(Response 2) As explained in earlier Response 1, the claim does not disclose how the adjusting is performed , only that adjusting leads to specific production rate. The adjusting therefore is understood as either expert knowledge or trial and error. The specification1 is silent on how the adjusting is performed and only discloses that adjustments are made. There is no nexus between the productivity index and ICV values (e.g. a formula to compute the ICV value from PI in the disclosure). For this reason this remains an idea of solution/field of use.

(Response 3) MPEP 2106.05(f)(1) states:
(1) Whether the claim recites only the idea of a solution or outcome i.e., the claim fails to recite details of how a solution to a problem is accomplished. The recitation of claim limitations that attempt to cover any solution to an identified problem with no restriction on how the result is accomplished and no description of the mechanism for accomplishing the result, does not integrate a judicial exception into a practical application or provide significantly more because this type of recitation is equivalent to the words "apply it". See Electric Power Group, LLC v. Alstom, S.A., 830 F.3d 1350, 1356, 119 USPQ2d 1739, 1743-44 (Fed. Cir. 2016); Intellectual Ventures I v. Symantec, 838 F.3d 1307, 1327, 120 USPQ2d 1353, 1366 (Fed. Cir. 2016); Internet Patents Corp. v. Active Network, Inc., 790 F.3d 1343, 1348, 115 USPQ2d 1414, 1417 (Fed. Cir. 2015). In contrast, claiming a particular solution to a problem or a particular way to achieve a desired outcome may integrate the judicial exception into a practical application or provide significantly more. See Electric Power, 830 F.3d at 1356, 119 USPQ2d at 1743.
Simply put here the goal is control the ICV, but the claim neither discloses how the adjustments are made to productivity index (PI) so that it matches known reservoir pressure, nor how once the PI is iterated/adjusted it translates to the ICV value. Both of them are an idea of solution as neither the claim nor the specification appears to have clear mapping for both the iteration and adjustment.
(Argument 4) Applicant has argued in Remarks Pg.:

(Response 4) Merely having data intensive computation or because the calculations (execution of physics-based model) are performed on a compute-intensive environment does not make claim patent eligible (MPEP 2106.04(a)(2)(III)). The counter example is:
• a claim to a method for rendering a halftone image of a digital image by comparing, pixel by pixel, the digital image against a blue noise mask, where the method required the manipulation of computer data structures (e.g., the pixels of a digital image and a two-dimensional array known as a mask) and the output of a modified computer data structure (a halftoned digital image), Research Corp. Techs., 627 F.3d at 868, 97 USPQ2d at 1280.
Further under Step2A Prong 2, the claim has to improve on the technology (MPEP 2106.05(a)/(h)) meaningfully. Productivity index (an abstract number) is like alarm limit and akin to In re Flook provides only field of use. Implying that it adjusts the valve (ICV) without any steps in claims/disclosure how the PI is related to ICV is merely field of use.

(Response 5) Examiner has updated the rejection to address applicant’s concerns in the rejection. Fig.10 was mapped to show multi-lateral well and not model by itself. Clarification the adjustment is not made in the comingled is mapped to show individual lateral is modeled and adjusted with threshold based comparison from known data (Figs.3, 4A). The argument does not specifically state what is known reservoir pressure. It is assumed this is measured pressure. Such is taught by Alanazi in field test PDHMs (pressure) and SWC ([0062] "... Modeling SWC will mimic downhole conditions and help to predict flow contributions from each lateral by estimating downhole parameters, such as PI, FBHP,..."). Applicant’s arguments are therefore considered but are respectfully not found to be persuasive. Applicant are welcome to request an interview to address these concerns with specific mapping how the deficiencies identified in the claims are supported in the specification.

Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claims 1-5, 7-12, 14-19 are rejected under 35 U.S.C. 101 because the claimed invention is directed to mental process without any additional elements that provide a practical application or amount to significantly more than the abstract idea.
Claims 1, 8 and 15:
Step 1: the claims 1, 8 and 15 are drawn to a method, a system and an An apparatus comprising a non-transitory, computer readable, storage medium respectively, falling under one of the four statutory categories of invention.
Step 2A, Prong 1: Taking claim 1 as representative, however analysis is applicable to claim 8 & 15 as well. The claim 1 limitations recite (bolded for abstract idea identification):
Claim 1
Mapping Under Step 2A Prong 1
1. A computer-implemented method, comprising:
obtaining,
generating, production scenarios based on the data associated with well completion, the data associated with inflow control valves, and the reservoir attributes of the multilateral wells;
inputting, the production scenarios into a physics-based model of the multilateral wells, wherein the physics- based model is built using one or more well tests, where a productivity index is estimated for laterals of the multilateral wells by iteratively altering the productivity index until an individual lateral flowrate is matched based on a known reservoir pressure;
obtaining, the simulation data comprising, for each scenario, per-lateral and total flowrates labeled to corresponding per-lateral inflow control valve settings and reservoir attribute;
predicting multilateral well production parameters using a machine learning model trained using the simulation data associated with the multilateral wells and target parameters associated with the multilateral wells; and
adjusting an inflow control valve setting associated with a respective multilateral well to achieve specific production flow rates from the respective multilateral well based on the predicted multilateral well production parameters.
See Step 2A Prong 2 and 2B.
Abstract Idea/Mental Step: The generation of production scenario appears to judgement/ opinion based on observation2 (viz the metadata). See MPEP 2106.04(a)(2)(III).
Abstract Idea/Mathematical concept/Mental Step: The inputting the production scenario into physics based model is a mental step which simply implies running the model (forming opinion) with data (observation of meta data and physics based model). See MPEP 2106.04(a)(3). The physics-based model it self if mathematical concept requiring executing of equation related physics3 of the well/reservoir. See MPEP 2106.04(a)(I)(B) & (C).
The inputting of data can also be considered under Step 2A Prong 2.
The estimation of productivity index is considered abstract idea (mental step based on possible mathematical concept) to form an opinion (adhoc matching decision based on known reservoir pressure) based on observation (estimated productivity index).
This may also be treated as an idea of solution under Step 2A Prong 2.
See Step 2A Prong 2 and 2B.
Abstract Idea/Mathematical concept: predicting parameters using machine learning model at high level of generality with no details of what is predicted, how it is predicted and how the model is trained for the specific application (multilateral well production parameters) is abstract idea at best. See MPEP 2106.04(a)(2)(I)(C). Also see Example 47 Claim 2 as generic training and outputting the parameter is patent ineligible. The training process4 involves evaluating data to determine best hyperparameters (weights). The plain meaning is that random search algorithms, which compute neural network hyperparameters are a series of mathematical calculations.
See Step 2A Prong 2 and 2B.
Under its broadest reasonable interpretation, these covers a mental process including an observation, evaluation, judgment or opinion that could be performed in the human mind or with the aid of pencil and paper. That is, nothing in the claim element precludes the step from practically being performed in the mind or with the aid of pencil and paper but for the recitation of generic computer components (Processor). Also the mathematical concepts disclosed may also be performed in the mind or with the aid of pencil and paper.
Claims 8 & 15 recites similar bolded limitations as above and those are rejected likewise.
Step 2A, Prong 2: In accordance with this step, the judicial exception is not integrated into a practical application.
In claim 1, all the steps recite additional element as at least one processor. The processor(s) is(are) recited at a high level of generality, i.e., as a generic computer performing generic computer functions. See MPEP 2106.05(f).
Claim 1
Mapping Under Step 2A Prong 2
1. A computer-implemented method, comprising:
obtaining,
generating, , production scenarios based on the data associated with well completion, the data associated with inflow control valves, and the reservoir attributes of the multilateral wells;
inputting,
where a productivity index is estimated for laterals of the multilateral wells by iteratively altering the productivity index until an individual lateral flowrate is matched based on a known reservoir pressure;
obtaining, with the at least one processor, simulation data associated with the multilateral wells output from the physics-based model, the simulation data comprising, for each scenario, per-lateral and total flowrates labeled to corresponding per-lateral inflow control valve settings and reservoir attribute;
predicting multilateral well production parameters using a machine learning model trained using the simulation data associated with the multilateral wells and target parameters associated with the multilateral wells; and
adjusting an inflow control valve setting associated with a respective multilateral well to achieve specific production flow rates from the respective multilateral well based on the predicted multilateral well production parameters.
As per MPEP 2106.05(g) the obtaining various data as claimed is considered as data gathering/extra solution activity.
As per MPEP 2106.05(f) use of generic computer components where the processor invokes computers or other machinery merely as a tool to perform an existing process. The limitation related to processor is removed from claim 1, however is implied in the claims 8 and 15 is mapped as generic component.
As per MPEP 2106.05(g) the inputting various data as claimed is considered as data gathering/extra solution activity. Use of processor is considered as above under MPEP 2106.05(f). The limitation related to processor is removed from claim 1, however is implied in the claims 8 and 15 is mapped as generic component.
Under MPEP 2106.05(f)(1) the claim recites only the idea of a solution or outcome i.e., the claim fails to recite details of how a solution to a problem is accomplished.
Here the solution (matching based on the known reservoir pressure) does not provide steps taken iteratively to alter the productivity index to cause the matching to happen, thereby failing to show details how the result is accomplished.
As per MPEP 2106.05(g) the obtaining various data as claimed is considered as data gathering/extra solution activity. Use of processor is considered as above under MPEP 2106.05(f). Under MPEP 2106.05(f)(1) the claim recites only the idea of a solution or outcome i.e., the claim fails to recite details of how a solution to a problem is accomplished. , where there is specific solution (what are the “multilateral well production parameters”?) is disclosed and no mechanism other than simply stating that is obtained using trained machine learning model. The input parameters (“simulation data associated with the multilateral wells and target parameters associated with the multilateral wells”) does not show the mechanism that would be required to train the model nor what and how the output of multilateral well production parameters are generated. Providing the details of the simulation data (as to what it is) is not sufficient show the mechanism to provide details of the physics-based model.
Further under MPEP 2106.05(h) use of machine learning model generically to output production parameters with no details how the neural network is trained and how the production parameters are derived from the trained neural network lead to simply the use of neural network in the field of predict multilateral well production parameters
Under MPEP 2106.05(g) predicting is considered as an output of the neural network and broad recitation of Production parameters as output is considered as post solution/extra-solution activity.
Under MPEP 2106.05(g)/(h), this is post solution activity and field of use.
Examiner Note: There is no nexus claimed/established between the “multilateral well production parameters” and the “inflow control valve (ICV) settings”, therefore this remains field of use as indicated above. This may further be idea of solution because it is not clear what the multilateral well production parameters are and how the ICV setting are computed to adjust the ICV. This would be beneficial to overcome the rejection under this statute.
In particular, the claim(s) recites the additional elements of a processor for the system claim, at a high-level of generality (i.e. a generic processor performing generic functions of computing and executing information such that it amounts to no more than mere instructions to apply the exception using a generic computer component). Accordingly, these additional elements do not integrate the abstract idea into a practical application because they do not impose any meaningful limits on practicing the abstract idea. See MPEP 2106.05(f).
Additionally, Claim 8 recites additional elements of “at least one processor, and at least one non-transitory storage media storing instructions that, when executed by the at least one processor”, which are recited at a high level of generality, i.e., as a generic computer performing generic computer functions. As per MPEP 2106.05(f) they do not integrate the judicial exception into practical application.
Additionally, Claim 15 recites additional elements (underlined) of “apparatus comprising a non-transitory, computer readable, storage medium that stores instructions that, when executed by at least one processor, cause the at least one processor to perform operations”, which are recited at a high level of generality, i.e., as a generic computer performing generic computer functions. As per MPEP 2106.05(f) they do not integrate the judicial exception into practical application.
Step 2B: As discussed above the claim fails to integrate of the abstract idea into a practical application and it for same reasons, the additional element of using a computer/processor to perform the claimed steps amounts to no more than mere instructions to apply the exception using a generic computer/processing component, and do not contribute significantly more to the judicial exception, as mapped above. The claims 1, 8 & 15 are therefore considered to be patent ineligible.
Claims 2, 9 & 16 recite “wherein multilateral well production parameters comprise inflow control valve settings corresponding to laterals of the respective multilateral well” further defining the what data is gathered. This type of limitation merely confines the use of the abstract idea to a particular technological environment (type of data gathered using extrasolution activity) and thus fails to add an inventive concept to the claims. MPEP 2106.05(g) & (h).
Claims 3, 10 & 17 recite “ dividing the simulation data into training and validation datasets; and training the machine learning model using a randomized search algorithm applied to the simulation data associated with the multilateral wells output from the physics-based model” , which are considered as abstract idea based on mental step (dividing limitation) and performing mathematical calculations (training step). The claims do not disclose any additional limitations that integrate the judicial exception into practical element or add significantly more to the judicial exception.
Claims 4, 11 & 18 recite “ comprising validating the trained machine learning model by evaluating R-squared values and mean absolute error (MAE) values.” , which are considered as abstract idea based on performing mathematical calculations (validating by performing mathematical calculation to determine R-squared and MAE steps). The claims do not disclose any additional limitations that integrate the judicial exception into practical element or add significantly more to the judicial exception.
Claims 5, 12 & 19 recite “ wherein the target parameters are defined by a predetermined well type” , which are considered as abstract idea based on mental step of picking the target parameters based on well type (See specification [0028] ). The claims do not disclose any additional limitations that integrate the judicial exception into practical element or add significantly more to the judicial exception.
Claims 6, 13 & 20 (Cancelled)
Claims 7 & 14 recite “ wherein the production scenarios are generated as permutations of the data associated with well completion, the data associated with inflow control valves, and the reservoir attributes of the multilateral wells..” , which are considered as abstract idea based on mental step which is based observation of datum as claimed (See specification [0022]-[0026] ). The claims do not disclose any additional limitations that integrate the judicial exception into practical element or add significantly more to the judicial exception.

Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim(s) 1-5, 7-12, 14-19 are rejected under 35 U.S.C. 103 as being unpatentable over US 20200362674 A1 by Alanazi; Amer et al., in view of US 20210133375 A1 by ZAGAYEVSKIY; Yevgeniy et al.

For example, the number of iterations used can be based on rules of thumb correlating the number of iterations with a number of variables (for example, ICVs). The optimized solution can reflect the current state of the calibrated model and can be implemented immediately to begin realizing production gains. After a production interval has occurred in which well/reservoir conditions are expected (or likely) to change, the calibration and optimization of the model can be repeated to reflect these changes.

Alanazi does not explicitly disclose the trained in the context to train the neural network (Emphasis on bolded).
Zagayevskiy explicitly disclose predicting multilateral well production parameters using a machine learning model trained using the simulation data associated with the multilateral wells and target parameters associated with the multilateral wells (Zagayevskiy: Fig.2A elelements [0014] "... a reduced parameter size are generated based on statistical and machine learning (deep neural network) approximation of a full physics flow simulator, i.e. the processing of a full physics flow algorithmic model...."); [0025] "... The plurality of reservoir data models 72 is previously generated data models generated by the full-physics flow simulator 64. The machine learning and training and validation module 74 can iteratively generate reduced parameter space algorithmic models from the computationally complex algorithmic model using at least one training dataset and at least one validation dataset, i.e. reservoir models, and at least one selected from a group of: input variables 56, output variables 58, updated reservoir model 76, history matching input variables 78, the optimized reservoir model 84, and optimization input variables 86....";).
It would have been obvious to one (e.g. a designer) of ordinary skill in the art before the effective filing date of the claimed invention to apply the teachings of Zagayevskiy to Alanazi reduce the parameter space to allow reservoir management teams to quickly make informed and effective decisions, there is a need for systems that can generate less computationally complex workflows yet still maintain an acceptable degree of accuracy by using machine learning in optimizing the reservoir management (Zagayevskiy: Abstract & [0002]; Alanazi: Abstract). The motivation to combine would have been that Zagayevskiy & Alanazi are analogous art to the instant claims in the field of reservoir management/completion to optimize the choke valve (ICV) for such management using machine learning (Zagayevskiy: [0014][0025] – showing machine learning using physics based model, [0032][0028] & Alanazi: Abstract [0070]-[0087] showing machine learning, [0041]-[0042]).
Regarding Claims 2, 9 and 16
Alanazi teaches wherein multilateral well production parameters comprise inflow control valve settings corresponding to laterals of the respective multilateral wells (Alanazi: [0068]-[0077]; See Fig.4B element 462-464 and Fig.10 showing inlet control valves (ICVs) for laterals 1012 of the respective multilateral wells being controlled) .
Regarding Claims 3, 10 and 17
Zagayevskiy teaches comprising: dividing the simulation data into training and validation datasets (Zagayevskiy: [0025] ) ; and training the machine learning model using a randomized search algorithm applied to the simulation data associated with the multilateral wells output from the physics-based model (Zagayevskiy: [0032] a plurality of trained algorithmic models from the physics based model as disclosed in [0025]) .
Regarding Claims 4, 11 and 18
Zagayevskiy teaches comprising validating the trained machine learning model by evaluating R-squared values and mean absolute error (MAE) values (Zagayevskiy: [0035] as mean square error MSE) .
Regarding Claims 5, 12 and 19
Alanazi teaches wherein the target parameters are defined by a predetermined well type (Alanazi: [0049] showing gas, oil and water zones for multilateral wells; [0106]-[0108] showing restricting the well-type production for gas and oil) .
Regarding Claims 6, 13 and 20 (Cancelled)
Regarding Claim 7
Alanazi teaches wherein the production scenarios are generated as permutations of the data associated with well completion, the data associated with inflow control valves, and the reservoir attributes of the multilateral wells (Alanazi: [0042][0067][0069], [0079]-[0087] use of genetic algorithm to generate scenarios population; [0094] based on collected data associated with well completion, ICV specification as data associated with inflow control valve; PVT & Permeability as reservoir attributes) .

1 Specification [0017] "... Additionally, the predictions made by the hybrid model provide for the adjustment of wellhead pressures in the wellhead 102 and the adjustment of the ICV's 112, 114, and 116...." & [0021] "...In particular, based on the final productivity index for each lateral, wellhead pressures (WHP), inline control valves (ICVs), or both are adjusted to achieve a desired productivity from the multilateral completion...."
2 See Specification [0022] "...For example, metadata includes a well's completion details, ICV details, reservoir attributes and the like.... In embodiments, this metadata dictates the type of production scenarios that can be generated." [0023]-[0026] offer no explanation of any specific methodology that would render generation of production scenario to not be mental step based on observation of metadata.
3 See Specification [0015] "...Generally, physics-based models are defined by one or more governing physics model equations to incorporate process variations using independent process parameters...."
4 See Specification [0032] "... Generally, initial machine learning model hyperparameters are set by a data scientist ahead of training and control implementation aspects of the model. The hyperparameters are distinct from the model parameters (e.g., input and output parameters), which are learned during training. In examples, hyperparameter tuning enables determining the combination of hyperparameter values for a machine learning model that performs the best (as measured on a validation dataset) for a problem. In embodiments, the randomized search algorithm fine tunes one or more hyperparameters, such as neural network size, number of nodes in each layer, learning rate, activation function, solver, and max number of iterations...."
