Electric Line Tractor-Based Conveyance in High Temperature Wells:A Collection of Local Case Stories

摘要

Texas and Louisiana are not typically thought of as extreme environments,but the Haynesville and the Eagle Ford do have some hot and deep areas that are being developed.High temperature environments require specialized,robust intervention tools designed to withstand longer periods of extreme heat. The industry's definition for'high temperature'ranges from 300°F to 400°F.Working in this environment requires careful preparation,as well as proven,reliable service providers and equipment.Established electric line tractor- based technologies running on AC power,as well as DC equipment have proven their application in these harsh and unforgiving environments.They offer additional benefits like reduced personnel and less heavy lifting,making these technologies inherently safer. This paper will share the learnings from a number of local operations in which this electric line technology has been deployed,including advances with DC electronics and some examples of AC electronics cases ranging from conveyance of logging tools to plug and perforating for fracture stimulations. In addition,this paper will examine the differences between AC and DC electric line equipment,their application in high-temperature environments,as well as discuss current trends within electronics for electric line equipment and future outlook for high-temperature equipment.
