Lex – Solution to ensure the rigless deployment and save up to 40% OPEX

Solution to ensure the rigless deployment and save up to 40% OPEX

Each replacement of failed submersible equipment or installation of a new ESP bears major OPEX. Our innovative solution allows the fast installation of submersible equipment with no damage to the bottom-hole area. The unique 29.5 ft (9 m) long Ultra-High-Speed ESP (UHS ESP™) by Lex is cable deployed into 3.5" (89 mm) tubing thru the wellhead lubricator.

Solution to ensure the rigless deployment and save up to 40% OPEX

For producing companies, replacing a faulty ESP, or installing a new one leads to heavy financial losses associated with payment to the workover crew, extra relocation of technical and human resources from other tasks to the current one, and profit loss due to downtime. Additionally, there is a risk of the trip-shows ruining the environment. That is why onshore, or offshore pulling-and-running operations are naturally unsafe and need highly qualified staff and special support equipment.

The standard submersible equipment requires a special workover service rig and killing fluid that may adversely impact the reservoir properties in the bottom-hole area.

We have developed an advanced solution that is especially relevant for offshore, geographically remote, and hard-to-reach oil fields. We offer a compact 29.5 ft (9 m) long Ultra-High-Speed (up to 12,000 rpm) electric submersible pump. The unit is cable-deployed in a casing and can be mounted through 3.5″ (89 mm) tubing. The installation is carried out through the wellhead lubricator.

UHS ESPTM installation does not require the workover rig, shutdown, or killing wells with a heavy fluid that damages the bottom-hole area, reduces productivity, or complicates putting a well on stream.

Our solution helps reduce OPEX up to 40%, prevent long-term negative impact to the bottom-hole area of the well, and enhance employee safety of work.

Ultra-High-Speed ESP (UHS ESP™)

Lex Ultra-High-Speed ESP (UHS ESP™), driven by a permanent magnet motor (PMM) and having an operating speed range from 1,000 to 12,000 rpm, is unrivaled worldwide. Due to its high nameplate operating speed of 10,000 rpm, the length of the UHS ESP™ is 2–3 times shorter than any conventional ESP. The efficiency of the Permanent Magnet Motor exceeds 91%, the use of hard-alloy materials gives our modular pump the abrasion resistance up to 2,000 ppm (2,000 mg/l).

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.
