Plug and abandonment service provider Abrado Wellbore Services has secured a multi-million dollar contract from Chevron to support the plug and abandonment of more than 30 wells offshore California.
Abrado said on Monday that the mature wells lie in Federal waters approximately 12 miles off the Californian coast.
All wells are exhibiting sustained casing pressure to varying degrees while some require dual string remediation for permanent P&A.
According to the company, the multi-year contract is the largest single contract won by Abrado in its 10-year history.
It will provide section milling using its proprietary Medusa VS variable stabilized dual string technology, comprehensive fishing services, and real-time downhole video diagnostics to support the operation under its IOV (Investigate, Operate, Validate) contract concept.
Some of the dual section milled windows will be greater than 100 feet long to provide increased rock to rock sealing and cement plug assurance.
Abrado CEO Sandy Esslemont said: “Multi-string section milling is a relatively recent process, but tool quality and project time have improved dramatically over a very short period.
“The California campaign is the latest step in our development and, along with other recent successful projects in the Gulf of Mexico, enhances our ambition to become a pre-eminent supplier to the global oil and gas community.”
