Artificial Lift Company’s Rigless ESP System Reaches Milestone for Reliability with 15 Months of Operation


HOUSTON, November 2, 2010—Artificial Lift Company’s rigless ESP system has completed nine pre-emptive wireline retrievals and redeployments at depth and has been running for more than 400 days in West Texas.

Developed in conjunction with ConocoPhillips, the system is a groundbreaking artificial lift solution for the oil and gas industry that significantly reduces ESP intervention costs by enabling rigless ESP workovers. It was approved for commercialization in October 2009, and it is scheduled for more installations in North America and the Middle East.

“Achieving more than 15 months run time and nine successful retrievals and redeployments at depth is a very important milestone for the ALC rigless ESP system. It will enhance customer confidence in both the new permanent magnet motor and the wet connector technology that ALC is implementing, and it will further strengthen our track record of reliable and durable system installations worldwide,” said ALC Vice President of Operations Peter Moulsdale.

ConocoPhillips has been testing the system for the past 18 months in this harsh well environment. Despite weather-related power outages and process trips, the system has accumulated more than 400 run days.

“The testing phase allowed us to identify and improve the installation’s functionality, resulting in flawless execution and three successive breaks and makes of the rigless ESP,” said John Patterson, engineering fellow at ConocoPhillips. “We are pleased with the functionality and reliability of the system, and we are now ready to move forward with two installations in Alaska.”

ALC President Geoff Kimber-Smith commented, “ALC is already seeing an increased market demand for cost-effective ESP technologies with lower intervention costs. The successful completion of this landmark project has created global interest from both international and national oil companies keen to maximize the uptime of their ESP wells and reduce operating costs.”
