Patent ID: 8727016

Claim:
An apparatus to enhance well control in slim completions, the apparatus comprising: casing positioned to support a slim bore of a hydrocarbon well, the slim bore having an inside diameter in the range of about two to seven inches so that the slim bore and associated casing define a slim completion; production tubing connected to and positioned at least partially within the casing to provide a pathway tin hydrocarbons dispersed from the well; a packer connected to the casing and the production tubing and extending therebetween to support the positioning of the production tubing within the casing and to prevent hydrocarbons from passing between an interstitial space between outer walls of the production tubing and inner walls of the casing proximal from the packer; an electric submersible pomp being operable to pump hydrocarbons from the well and thereby fluidly travel to the surface, the pump being positioned within the casing, having at least a portion thereof disposed to extend from distal end portions of the production tubing when positioned within the casing, and having an outer diameter smaller than the inner diameter of the production tubing, the pump including: a pump intake positioned outside the production tubing within the casing so that the hydrocarbons enter the pump intake from the interstitial space between the outer surfaces of the portion of the pump disposed to extend outwardly from distal end portions of the production tubing within the casing and the inner walls of the casing, a pump discharge positioned within the production tubing so that the pumped hydrocarbons are discharged within inner walls of the production tubing and to the surface, the production tubing terminates adjacent a distal end portion of the pump discharge, and a medial pump body portion extending between the pump intake and the pump discharge through which the hydrocarbons flow from the pump intake to the pump discharge; an electric, cable connected to the pump to deploy the pump within the casing and through the production tubing and to provide a power transmission pathway to transmit power to the pump; a subsurface prevention valve connected to inner walls of the casing and distally disposed from the pump within the slim bore, the subsurface prevention valve being operable to prevent hydrocarbons from flowing into the interstitial space between the outer surfaces of the portion of the pump disposed outside the production tubing within the casing and the inner walls of the casing; and an electric wet connection cable connected to a distal end of the pump and a proximal end of the subsurface prevention valve to provide power to the subsurface prevention valve from the electric cable through the pump.
