20100143166 | DOWNHOLE PUMPING SYSTEM - A downhole motor and pump assembly for use in a tube has a support that suspends the assembly downhole, a housing capable of forming a seal against an inside surface of the tube to divide the tube into a lower region below the seal and an upper region above the seal, an electric motor, and a power supply for the electric motor. A hydraulic pump driven by the electric motor has a high pressure output. A piston is operated by a directional valve such that the high pressure output from the hydraulic pump is directed by the directional valve alternately above and below the piston so as to reciprocate the piston. A fluid pump driven by the piston pumps well fluid from the lower region to the upper region. | 06-10-2010 |

20120132442 | CONTROL OF FLUID FLOW IN OIL WELLS - A flow restrictor for controlling the flow of cement or other fluid in oil wells comprises a plurality of restrictor elements, each defining first and second apertures, which are assembled in a stacked configuration and slidingly inserted into the well casing or other tubing so that the first apertures define a direct flowpath, preferably including a non-return valve, and the second apertures define a second, indirect flowpath between the elements and the inner surface of the tubing. The elements include seals for fluidly sealing each element in the bore of the tubing which are preferably slidably retractable and resiliently radially outwardly biased so as to adapt conformably to different tubing types having different internal diameters. The restrictor may slide along the tubing in use. | 05-31-2012 |
20120222853 | METHOD OF DEPLOYING AND POWERING AN ELECTRICALLY DRIVEN DEVICE IN A WELL - According to the present invention, there is provided a system for installing a powered device in a downhole tube, the system comprising a power line disposed along a production tube and terminating in a first power connector and an orientation profile disposed in the vicinity of the first power connector. An assembly includes a powered device having a second power connector and an extending orientation means capable of radial outward movement from the assembly. The powered device being lowered down the production tube, causing the extending orientation means to be urged radially outwards to engage with the orientation profile and orient the device, so that the first power connector means and second power connector means engage to connect the powered device to the power line in an automatic manner. | 09-06-2012 |
20120222856 | COILED TUBING DEPLOYED ESP - According to the present invention, there is provided a well pumping system comprising a length of coiled tubing extending to the surface of the well, a first electric pump, a first electric motor, and a sealing means that seals against the side of the well. The sealing means include a first fluid path through which coiled tubing is in fluid communication with the well beneath the sealing means, and a second fluid path through which first electric pump is in fluid communication with the well beneath the sealing means. | 09-06-2012 |
20130062050 | MATING UNIT ENABLING THE DEPLOYMENT OF A MODULAR ELECTRICALLY DRIVEN DEVICE IN A WELL - An electric pump assembly is provided in a well, the pump comprising an electric motor module having a first outer housing and a first mating means, an electric pump module having a pump inlet and a pump outlet, and a second outer housing and a second mating means. In one aspect, the electric motor module and electric pump module are capable of being reversibly joined together by the first and second mating means, as the electric motor module includes a first rotating member that is capable of rotating relative to the first outer housing, and the electric pump module includes a second rotating member that is capable of rotating relative to the second outer housing. In this way, the first rotating member and second rotating member can transfer torque when the electric motor module and electric pump module are joined. In another aspect, a flowpath is provided in each module, the flowpaths fluidly communicating when the modules are joined. | 03-14-2013 |
