Low-pressure method and apparatus of producing hydrocarbons from an underground formation using electric resistive heating and solvent injection

A method of producing hydrocarbons from an underground formation having an array of horizontal wells has the steps of: inserting one or more heater strings into at least one heater well section, the heater string comprising a heating element and a flow passage for transporting fluid from a fluid input to at least one injection port; activating the heating element of the heater string to heat the formation sufficient to produce hydrocarbons from the formation immediately adjacent to the at least one heater well section; heating and injecting a solvent into the at least one heater well in the gaseous phase through the at least one injection port of the heater string such that the solvent is injected into the voidage in the at least one heater well section created by the produced hydrocarbons; and producing hydrocarbons from at least one producer well.. . ...

Method of installing coiled tubing with a plurality of integrated large diameter external assemblies

A method of installing a coiled tubing string having a plurality of external assemblies includes injecting the coiled tubing string into a well with a coiled tubing injector, when a first external assembly on the coiled tubing string reaches the coiled tubing injector, transferring support of the coiled tubing from the coiled tubing injector to a coiled tubing snubber located below the coiled tubing injector, opening the coiled tubing injector to an extent sufficient to allow passage of the first external assembly thereby, and actuating the coiled tubing snubber to move the first external assembly past the coiled tubing injector. The first external assembly has an outside diameter that is larger than an outside diameter of the coiled tubing string.. ... Petrospec Engineering Ltd
