Lex – +20% production gain, -40% energy saving at a group of oil fields

+20% production gain, -40% energy saving at a group of oil fields

A perfect example of our Ultra-High-Speed ESP (UHS ESP™) in action can be found in the group of fields, where we successfully delivered the mass implementation of this innovative technology. The client in this case needed a significant improvement to the efficiency and safety of their oil production with the end goal of reducing their total cost of ownership (TCO). Since the start of our project with them, we have successfully installed more than 300 units.

Results

Fields’ reservoirs are found at 6,900–8,200 ft TVD (2,100–2,500 m TVD). Oil wells are drilled from well pads, ESP friendly deviated along 8,860–11,500 ft MD (2,700-3,500 m MD) and completed with 7″ (177,8 mm) and 6.61″ (168 mm) API Casing. Downhole temperatures are ranging between 176 and 212 °F (80–100 °C).

The following complicating factors stalled to reach the production measures:

After doing research and detailed analysis, we proposed installing several models of Ultra-High-Speed ESPs with a nameplate operating speed of 10,000 rpm:

Upon every phase of technology deployment the client evaluated obtained results. They were found stable and consistent with prior results, allowing to development of a solid economic model.

Since 2016 UHS ESPTM systems are approved for use in group of fields under Lex engineering support and supervision. 

We offer a centralized approach to the monthly delivery of equipment for installation and maintenance, due to the compact design of our UHS ESPTM units and minimum on-site preparation requirements. This allows us to avoid additional field workshops as the preparation of equipment can be conducted at a main repair facility and delivered directly to the field being ready for the installation (plug-and-play design).

Our results consistently demonstrate the high potential of Lex UHS ESPTM to optimize production and provide operational advantages in harsh well conditions.

UHS ESPTM advantages vs. standard equipment

Implementation of Lex Ultra-High-Speed (UHS ESPTM) technology is increasing despite oil prices drop and OPEC+ 2020-2021 restrictions. For today, we installed more than 500 units at offshore and onshore projects worldwide.
