  • Patent number: 11339612
    Abstract: A mobile service rig includes an onboard rechargeable electric power storage system (e.g., a battery, supercapacitor, etc.) for powering the rig's hoist and drive wheels. Under battery power, the rig travels overland to service wellbores at various wellsites. Once at a wellsite, a pumpjack at the site is de-energized, and the hoist proceeds to remove and reinstall wellstrings (e.g., tubing and sucker rods). While the pumpjack is de-energized, the rig's onboard rechargeable electric power storage system taps into the electric power source normally used for the pumpjack. The drive wheels and hoist can drain the rig's rechargeable electric power storage system, but the pumpjack's electric power source can gradually recharge it while the rig is servicing the wellbore. Moreover, when the hoist lowers the wellstring back down into the wellbore, the energy generated by that operation is recovered and used for replenishing the rig's rechargeable electric power storage system.

  • Patent number: 9429000
    Abstract: A system comprising a well flow optimization program and associated control equipment for monitoring changing variables and well conditions and dynamically performing adjustments to one or more established set points. The system is designed to work with a plunger lift system but is also functional on a well that is not running a plunger lift or any type of artificial lift system. The system is also capable of controlling open flow and open flow set points and sales flow and sales flow set points by means of a pneumatic flow control device. The disclosed system also minimizes the time that is needed to optimize a well by a producer/operator.

  • Patent number: 9376887
    Abstract: This stuffing box (46) defines a circulation passage (66) of a cable working line (28), a packer (70), and a back-pressure resistant valve (74). The passage (66) extends between an upstream end (62) of the stuffing box (46), intended to be connected to a well, and a downstream end (64). The back-pressure resistant valve (74) is arranged in the passage (66) to prevent, in case of break of the line (28), the back-pressure of a fluid from the upstream end (62) towards the downstream end (64). The or each packer (70) is situated between the upstream end (62) of the stuffing box (46) and the back-pressure resistant valve (74). No packer (70) is arranged between the back-pressure resistant valve (74) and the downstream end (64).

  • Patent number: 9297247
    Abstract: A method for controlling the liquid load size of a plunger lift well during the shut in time of the well to facilitate a controlled plunger rise. Intra-cycle control allows dynamic adjustments within a cycle to keep the plunger running and not stalling out or rising too fast. The method includes the steps of shutting in the well to build up pressure within the well, adjusting a size of a liquid slug within the tubing while the well is shut in, opening a valve to relieve pressure within the well and raise the plunger within the tubing, pushing the liquid slug out of the well with the plunger, and closing the valve wherein the plunger falls within the tubing. The intra-cycle adjustments include reducing the size of the liquid slug for preventing fluid loading and increasing the size of the liquid slug for controlling a rise rate of the plunger.

  • Patent number: 9291033
    Abstract: Surface controlled subsurface control valves for use in wells and methods of controlling the same. In one embodiment, a valve includes a valve body, a bore closure assembly, a mechanical linkage, a drive assembly, and a control assembly. The valve body defines a bore for fluid to flow through when the bore closure assembly is in an open position. When the bore closure assembly is in its closed position, the bore closure assembly prevents fluid from flowing through the bore. The mechanical linkage is operatively connected to the bore closure assembly and to the drive assembly. The primary control assembly determines a force to apply to the mechanical linkage based on a present operating condition of the valve and causes the drive assembly to apply the determined force to the mechanical linkage. As a result, the mechanical linkage drives the bore closure assembly.

  • Patent number: 9194214
    Abstract: A method and system of controlling the temperature of fluids produced from a reservoir to prevent overheating of an adjacent geological formation. A cooling fluid is supplied through an annulus formed between a production tubing and a production casing, which are in fluid communication with the reservoir. The cooling fluid is mixed with the reservoir fluid, and the fluids are produced through the production tubing. The temperature of the produced fluids is controlled or reduced by heat exchange with the cooling fluid supplied through the annulus to prevent excessive heat dissipation to the geological formation.

  • Patent number: 9085966
    Abstract: Disclosed is a method for transient testing of an oil well to determine the individual, distinct skin factor components of an apparent skin factor, which includes opening the well to a first predefined choke setting to allow the reservoir fluid to flow through the well for a first predefined period of time, and measuring a production rate of the reservoir fluid through the well, when the first predefined period of time expires. The method further includes performing a shut-in of the well for a first predefined build-up period, and repeating, when the first predefined build-up period expires, the steps of the flowing, the measuring, and the performing for at least two additional choke settings. The distinct skin factor components of the apparent skin factor are determined using a graphical relationship between the determined apparent skin factors and the measured production rates.
