Through-Tubing-Conveyed ESP Technology Overcomes North Slope Challenges
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.
How Will Subsea-Processing Technologies Enable Deepwater-Field Developments?
This study examines how subsea processing (SSP) can develop into an important enabling technology for future ultradeepwater-field developments and long-distance tiebacks.
Gas Lift Use Grows in Permian
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.
Operators Begin Considering Pumps on Older Subsea Fields
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.
Evaluation of Intermittent-Flow Behavior Upstream of Electrical Submersible Pumps
This work experimentally investigates the behavior of an intermittent multiphase liquid/gas flow that takes place upstream of an electrical submersible pump (ESP).
Methodology Evaluates Artificial-Lift Requirements Amid High Uncertainty
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.
Encapsulated ESP Handles Multiphase Flows To Extend Run Life and Boost Oil Recovery
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.
Production Optimization With Artificial-Lift ESP Pilot Systems in a Mature Oil Field
A production-optimization strategy of an artificial-lift system resulted in the mitigation of challenges related to reservoir heterogeneities and completion design.
High-Power ESP Tubing-Hanger Connector for Deepwater Downhole Applications
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.
Applying Root-Cause Failure Analysis Enhances Artificial-Lift Performance
This paper describes the use of a root-cause-failure-analysis (RCFA) process to improve artificial-lift-system performance in a project in Chad.
Heavy-Oil Papa-Terra Project Uses Innovative Solutions in Deep Water
The Papa-Terra field in the Campos basin in Brazil is identified as having an oil interval of 14.6°API in turbidite sandstones.
