electrical submersible pumps

Electrical-submersible-pump (ESP) technology is a proven artificial-lift method for shallow, low-pressure reservoirs such as those found in the West Sak viscous oil field in Alaska.

This study examines how subsea processing (SSP) can develop into an important enabling technology for future ultradeepwater-field developments and long-distance tiebacks.

Unconventional production patterns in the Permian Basin are leading producers to replace electrical submersible pumps (ESPs) with gas lift, which had been little used there.

The sharp downturn in the offshore oil business has sparked interest in using subsea pumps to add production. If those conversations turn into orders, it may convert this rarely used option into a commonly used tool for extending the life of offshore fields.

This work experimentally investigates the behavior of an intermittent multiphase liquid/gas flow that takes place upstream of an electrical submersible pump (ESP).

When evaluating artificial-lift requirements, sometimes data present uncertainties at the initial planning stage. This paper presents the integrated and structured methodology that was used to deal with high-uncertainty conditions.

Electrical submersible pump (ESP) systems are critical to achieving the maximum production rates and reservoir pressure drawdown that improve ultimate recovery. But variable volumes of gas in unconventional wells can pose challenges for performance of the ESP.

A production-optimization strategy of an artificial-lift system resulted in the mitigation of challenges related to reservoir heterogeneities and completion design.

It was established that improving the reliability of the TH-connector system has a direct effect on the unintervened life of the ESP electrical system.

This paper describes the use of a root-cause-failure-analysis (RCFA) process to improve artificial-lift-system performance in a project in Chad.
