Lex – Thru-Tubing ESP

Thru-Tubing ESP

We have developed the upgraded Lex UHS ESP™ that is cable deployed through the 3.5" (89 mm) tubing. The system can quickly resume production in non-operating wells caused by upcoming maintenance or pump failure. Compact UHS ESP™ is riglessly cable-deployed into the tubing through the wellhead. The technology successfully replaces an expensive workover and prevents clogging of the bottom-hole area without killing fluid. The high nameplate operating speed (12,000 rpm) of the ESP and the permanent magnet motor ensure a compact design and easier installation.

Thru-Tubing ESP

Advantages

Overview

Downtime of wells caused by pump failure results in multimillion losses for oil-producing companies. The workover can take from one week till six months due to waiting for the workover crew, disassembly and replacement of the submersible equipment and, commissioning.

We have developed an advanced solution that is especially applicable for offshore, difficult access, or remote fields. A compact Ultra-High-Speed Electric Submersible Pump system (up to 12,000 rpm) 29.5 ft (9 m) long is cable-deployed through the wellhead lubricator. The system can reduce downtime by 80% and quickly resume production a few hours later required for installation.

The cable deployed Thru-Tubing ESP technology is essentially a system where the components are inverted in comparison with standard ESP: control station – motor – seal section – gas separator – pump – packer.
