Abstract

A system is provided that is capable of providing heat across a produced interval during oil and gas production to minimize or reduce undesirable formation of gas hydrates in the wellbore. In one embodiment, the configuration provides a means to recycle heat generated by an electrical submersible pump. Heat from the pump may be applied downhole. One configuration is capable of providing for downhole separation of gas from produced fluids to reduce or eliminate gas transit through the pump. A heating element also may apply heat to produced fluids. An orifice may apply heat to produced fluids. The wellbore being drilled to a depth having a subterranean formation temperature that is high enough to elevate a temperature of the production fluids to a predetermined temperature such that the temperature of the production fluids is elevated to the predetermined temperature by at least the depth of the wellbore.
