摘要： A hydraulic fracturing tree wing is formed with a studded hydraulic valve next to a manual valve. The stud-to-flange connection allows for a shorter, lighter wing. The studded hydraulic valve maybe a gate valve that includes a T-slot coupling between an operating stem and the gate. A bonnet seal ridge may be formed to withstand undue deformation during operation that wears or destroys seals. A method for forming a hydraulic fracturing tree assembly includes using a flanged manual valve with a studded hydraulic valve. Other valves and methods are presented.

摘要： A system is provided that include a safety device configured to mount in a mineral extraction system and block axial movement of a plug in the mineral extraction system while the plug is released from a retainer. The safety device may be a sleeve configured to receive screws or other retention mechanism in a tubular. A method is provided that includes installing a plug safety catch into a tubular of a mineral extraction system in which the plug safety catch is configured to block axial movement of a plug in response to a pressure differential while the plug is released from a mount position.

摘要： A device for covering a pipeline from a wellbore comprising a cover comprising at least one lower bearing surface suitable for being mounted on an end of a vertical annular pipeline of a wellbore. The device includes a distribution elbow comprising a lower end, intended to be connected to a pipe of the wellbore, that extends vertically downwards from the cover and an upper end extending horizontally. The cover and the distribution elbow form a monobloc assembly.

摘要： A system includes a bridge seal assembly configured to form a seal within mineral extraction equipment. The bridge seal assembly includes an annular bridge seal having an accordion-shaped body portion with a plurality of folded portions. Each of the plurality of folded portions extends circumferentially about the annular bridge seal, and the plurality of folded portions are configured to enable the annular bridge seal to expand and contract with the mineral extraction equipment to maintain the seal. The bridge seal assembly also includes a reaction ring and one or more wedge rings configured to be inserted between the annular bridge seal and the reaction ring to actuate the annular bridge seal.

摘要： In accordance with some embodiments of the present disclosure, a method of computational modeling for tracking ball scalers in a wellbore is disclosed. The method may include, for a time step, calculating a number of ball sealers to inject into a wellbore, injecting the ball sealers, determining a length of the wellbore occupied by a fluid, and computing a spacing between each ball sealer in the length of the wellbore occupied by the fluid. The method may include calculating a first position of a ball sealer, determining a velocity the ball sealer, and computing a second position of the ball sealer. The method may include recording a number of active ball sealers and open perforations in the wellbore, calculating a ball sealer skin per division, and determining a fluid flow rate. The method may include selecting parameters for a stimulation operation in the wellbore based on the fluid flow rate.
