AccessESP's wireline retrievable electric submersible pump (ESP) system reduces the impact of deferred production and rig cost. A permanent magnet motor and a side pocket wet connect system were integrated to allow slickline/wireline ESP retrieval on a live well. The design also allows fullbore access to the lower completion when the ESP is retrieved. The goal is to integrate these technologies into a simplified rigless conveyance system that reduces HSE exposure and risks, reduces opex and offers cost-effective production optimization. Traditionally, when an ESP performance deteriorates or fails, or when an operator needs to access the lower completion for well repair or remediation, the only option is to pull the entire tubing string to surface, sometimes in remote or offshore operations with intervention costs ranging from $3 million to $15 million. There is often an opportunity cost associated with production downtime or well damage from kill fluid. HSE risks are associated with heavy workover operations. Many of these costs and risks can be eliminated when using wireline retrievable ESP. AccessESP systems mitigate these challenges, providing an alternative for well completion and ESP conveyance that allows ESPs to be changed out without a rig, on a live well and with reduced surface equipment.
