A study of a mature onshore field with more than 70 rod-pumped wells found several ways for improving pumping operations. The profitability of rod pumping is a direct function of the energy ...

Lufkin Industries (“Lufkin”), a global leader in artificial lift solutions, has been awarded by Petroleum Development Oman’s (“PDO”), a multi-year performance contract to deliver Rod Driven ...

A pilot project on a portable variable-speed-drive and load cell for obtaining counterbalance effect (CBE) data in the Duri steamflood improved the sucker-rod pumping efficiency from wells that had ...

Sucker rod pumping systems are a well‐established artificial lift method in oil extraction, valued for their mechanical simplicity and reliability. However, these systems operate under complex ...

Key insight: All lift systems target the same physics: reduce mixture density or add head so that nodal balance at the wellbore yields the desired rate. 2.3 Select lift method aligned to fluid, depth, ...
