Application of Downhole Electric Heat Trace System in Arctic Completions

Abstract: Approximately 30 downhole electrical heat trace systems are currently being utilized for the purpose of: freeze protection, mitigation of hydrate and heavy hydrocarbon accumulation in tubing strings, and viscosity reduction in the completions producing from the Schrader Bluff formation in the Milne Point field. To accomplish the intended objectives the Current system utilizes a self-limiting heat trace cable strapped to outside of the tubing to a depth of 2260'. These systems have become an integral part of th… Show more

“…Currently, the average reservoir pressure is between 1400 and 1750 psi depending on the producing fault block. The geothermal gradient from surface to 2000 ft is 0.8" F/100 ft, due to the presence of a permafrost layer that extends to this depth (Fox & Earsley, 1998). From that point the geothermal gradient increases to 3" F/100 ft.…”

“…Electrical heating includes not only attaching a heater outside the tubing but also installing a heater at the bottomhole [12]. An electric trace heater which is attached on the outer wall of the tubing introduces heat to the inside of the tubing to control the outbreak of paraffin, asphaltene, sulfur, hydrate and other precipitates [13].…”

“…An electric trace heater which is attached on the outer wall of the tubing introduces heat to the inside of the tubing to control the outbreak of paraffin, asphaltene, sulfur, hydrate and other precipitates [13]. This technique with an electric submersible pump (ESP) was announced as a general method in Northern Alaska [12]. Downhole heating technique is the way to increase oil production by installing a heater at the bottomhole.…”
