|20130315751||COMPACT CABLE SUSPENDED PUMPING SYSTEM FOR LUBRICATOR DEPLOYMENT - A method of installing or retrieving a pumping system into or from a live wellbore includes connecting a lubricator to a production tree of the live wellbore and raising or lowering one or more downhole components of the pumping system from or into the wellbore using the lubricator.||11-28-2013|
|20130209290||ELECTRIC SUBMERSIBLE PUMPING SYSTEM FOR DEWATERING GAS WELLS - A pumping system includes a submersible high speed electric motor operable to rotate a drive shaft; a high speed pump rotationally fixed to the drive shaft; an isolation device operable to expand into engagement with a tubular string, thereby fluidly isolating an inlet of the pump from an outlet of the pump and rotationally fixing the motor and the pump to the tubular string; and a cable having two or less conductors, a strength sufficient to support the motor, the pump, and the isolation device, and in electrical communication with the motor. A maximum outer diameter of the motor, pump, isolation device, and cable is less than or equal to two inches.||08-15-2013|
|20130192824||COMPACT CABLE SUSPENDED PUMPING SYSTEM FOR DEWATERING GAS WELLS - A motor includes two or more sections. Each section includes a submersible tubular housing and a stator core disposed within the housing. The stator core has one or more lobes and each lobe has a winding wrapped therearound. The motor further includes a rotor disposed within the housing and including a shaft and a rotor core. The rotor core has two or more lobes. Each section is incrementally oriented so that the sections may be operated to mimic a multi-phase motor.||08-01-2013|
|20130098632||GRADATIONAL INSERTION OF AN ARTIFICIAL LIFT SYSTEM INTO A LIVE WELLBORE - A method of inserting a downhole assembly into a live wellbore, includes: assembling a pressure control assembly (PCA) onto a production tree of the live wellbore; inserting a first deployment section of the downhole assembly into a lubricator; landing the lubricator onto the PCA; connecting the lubricator to the PCA; lowering the first deployment section into the PCA; engaging a clamp of the PCA with the first deployment section; after engaging the clamp, isolating an upper portion of the PCA from a lower portion of the PCA; and after isolating the PCA, removing the lubricator from the PCA.||04-25-2013|
|20100326670||LIFT WASH-THROUGH FACILITY - An apparatus for pumping fluid, the apparatus including a pump housing including a plunger connected to a terminal end of a coiled tubing and a first port. The apparatus further including the plunger configured to move longitudinally upward and downward, wherein the plunger includes a second port and a surface pumping unit configured to modulate between two modes, a first mode configured to limit a stroke length of the plunger so that the first and second ports do not engage, and a second mode wherein the first and second ports engage. Also, a method for pumping fluid into a wellbore using an apparatus, the method comprising inserting a housing including a coiled tubing and a plunger into the wellbore, wherein the plunger is located at a terminal end of the coiled tubing, and wherein the housing includes a first port and a plunger includes a second port. The method further including moving the plunger longitudinally upward and downward within the housing wherein a stroke length of the plunger is limited during the moving the plunger and extracting fluid from the wellbore. The method further including extracting fluid from the wellbore, pulling the plunger longitudinally upward until the first and second ports are aligned, and circulating fluid into the wellbore through the coiled rubbing and first and second ports discharging into an annulus of the wellbore.||12-30-2010|
