Baku, Azerbaijan, Dec.19
By Leman Zeynalova – Trend:
Canada’s Zenith Energy company, which is the operator of Azerbaijan’s largest onshore block of oil fields Muradkhanli-Jafarli-Zardab, expects to complete the workover of well Z-28 by the end of January 2018, a source in the country’s oil and gas market told Trend.
“The company confirms that it has cleaned out well Z-28 to reach the top of the slotted liner at a depth of 3574 meters. The top of the tubing can now be cleaned to total depth at 3944 meters,” said the source.
In the post-workover inspection of the wellhead, Zenith's petroleum engineers observed a leak during a pressure test from the wellhead in the 9 5/8 inches casing seal assembly.
“To resolve this problem, the company has contracted a UK-based, worldwide leader in oilfield leak-sealing technology, with an established presence in Azerbaijan. Zenith has been informed that various resin compounds will be required to successfully seal the wellhead following an engineering study currently underway by the aforementioned company. Zenith expects the estimated completion time of this study to be delayed by the upcoming holiday season in the United Kingdom and Azerbaijan, and to have fully completed the workover of well Z-28 by the end of January 2018,” added the source.
Azerbaijan’s state oil company SOCAR and Zenith Aran Oil Company signed a Rehabilitation, Exploration, Development and Production Sharing Agreement (REDPSA) in March 2016 for a block that includes the Muradkhanli, Jafarli and Zardab oilfields. These fields cover an area of 642.2 square kilometers. Production under the agreement began in August of 2016.
Zenith holds a 80-percent participating interest in the three fields within the contract area, while SOCAR retains the remaining 20 percent. The duration of the agreement is 25 years, with a potential extension of 5 additional years.
