DETAILED CORRESPONDENCE
Status of Application
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claims 1-20 have been examined in this application. This communication is a Non-Final Rejection in response to the Application filed on July 30, 2024.
Claim Objections
Claims 1-9 & 14 are objected to because of the following informalities:
Claim 1 appears to recite “a tubing string component” and “the first tubing string” interchangeably. Consistency in terminology is required. Appropriate correction is required. For purposes of examination, the Office considers Claim 1 with this limitation amended as set forth below. Claims 2-9 are also objected to for being dependent on Claim 1.
Claim 4 recites “to regulate an injection of gas from the at least one pressurized gas container into the passageway”, whereas parent Claim 1 recites “release a gas from the at least one pressurized gas container into the passageway”. Consistency in terminology is required to improve clarity. Appropriate correction is required. For purposes of examination, the Office considers Claim 4 with this limitation amended as set forth below.
Claim 7 recites “further comprising a series of chamber assemblies fluidly coupled to each other above the packer”. As this limitation broadly recites any chamber assembly, an amendment is required to improve clarity. For purposes of examination, the Office considers Claim 7 with this limitation amended as set forth below. Claim 8 is also objected to for being dependent on Claim 7.
Claim 14 recites “an external surface thereof”. As this limitation broadly recites any external surface, an amendment is required for clarity. For purposes of examination, the Office considers Claim 14 with this limitation amended as set forth below.

Appropriate correction and/or clarification is required. Claims 17-20 are also rejected for being dependent on Claims 16 & 17, respectively. For purposes of examination, the Office considers Claims 16-19 as set forth below.
Claims 1-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention.
Claim 1 recites “the at least one chamber assembly comprising: a mandrel positioned adjacent to a passageway, the passageway extending from a top connection to a bottom connection, a mandrel chamber located within the mandrel, comprising at least one pressurized gas container fluidly coupled to a first end of at least one friction coil, and a shearing disk operatively coupled to a second end of the at least one friction coil, the shearing disk positioned within the passageway”. As recited, the claim comprises one or more embodiments with the at least one chamber assembly comprising various combinations of a plurality of pressurized gas containers and/or a plurality of friction coils coupled to a single shearing disk as instantly claimed; where it is unclear how all such combinations of the chamber assembly are configured to release a gas to relieve hydraulic pressure as instantly claimed.
Claim 1 recites “the at least one chamber assembly comprising” and “a tubing string component fluidly coupled to the bottom connection of the at least one chamber assembly, the passageway and the first tubing string together defining a fluid pathway from the subsurface formation to the surface collection point”. For embodiments with more than one chamber assembly, it is unclear how a plurality of bottom connections connect to a single tubing string component to define a fluid pathway as instantly claimed. Figure 3 appears to present a plurality of chamber assemblies where the bottom connections of chamber assemblies appears to couple with the top connection of the adjacent chamber assembly, and not the tubing string component.
Claim 1 further recites “a friction coil”. It is unclear what this limitation refers to, and what it includes and excludes. For purposes of examination, the Office considers a “friction coil” as a “coil”.
As such, subsequent limitations in dependent claims related to these respective features are also unclear. Appropriate correction and/or clarification is required. Claims 2-9 are also rejected for being dependent on Claim 1. For purposes of examination, the Office considers Claim 1 and the respective dependent claims as set forth below.
Claim 10 recites “A chamber assembly for producing a multiphase formation fluid from a subsurface formation, comprising: a mandrel positioned adjacent to a passageway, the passageway extending from a top connection to a bottom connection; a mandrel chamber located within the mandrel, the mandrel chamber comprising: at least one pressurized gas container, at least one friction coil having a first end and a second end, and an injection port, wherein the first end of the at least one friction coil is fluidly coupled to the at least one pressurized gas container and the second end of the at least one friction coil is fluidly coupled to the injection port; and a shearing disk operatively coupled to the injection port, the shearing disk positioned within the passageway”.

Claim 10 further recites “a friction coil”. It is unclear what this limitation refers to, and what it includes and excludes. For purposes of examination, the Office considers a “friction coil” as a “coil”.
As such, subsequent limitations in dependent claims related to these respective features are also unclear. Appropriate correction and/or clarification is required. Claims 11-15 are also rejected for being dependent on Claim 10. For purposes of examination, the Office considers Claim 10 and the respective dependent claims as set forth below.

As recited, the claim comprises one or more embodiments with the chamber assembly connected to a plurality of tubing strings and comprising various combinations of a plurality of pressurized gas containers and/or a plurality of friction coils coupled to a single injection port that is coupled to a single shearing disk as instantly claimed; where it is unclear how all such combinations of the chamber assembly are employed in the method to producing a multiphase formation fluid as instantly claimed.
Claim 16 recites “at least one chamber assembly”, “at least one chamber assembly fluidly coupled to the at least one tubing string component” and “the bottom connection coupled to the at least one tubing string component”. For embodiments with more than one chamber assembly, it is unclear how a plurality of bottom connections connect to one or more tubing string components as instantly claimed. Figure 3 appears to present a plurality of chamber assemblies where the bottom connections of chamber assemblies appears to couple with the top connection of the adjacent chamber assembly, and not the tubing string component.
Claim 16 further recites “a friction coil”. It is unclear what this limitation refers to, and what it includes and excludes. For purposes of examination, the Office considers a “friction coil” as a “coil”.
As such, subsequent limitations in dependent claims related to these respective features are also unclear. Appropriate correction and/or clarification is required. Claims 17-20 are also rejected for being dependent on Claim 16. For purposes of examination, the Office considers Claim 16 and the respective dependent claims as set forth below.
