In 2021, ERIELL Group won a tender from Uz-Kor Gas Chemical and signed a contract to work on 150 wells at the Surgil field in the Republic of Karakalpakstan. ERIELL Group will carry out workover and sidetracking works at the bottom of the Aral Sea.
The project is being implemented within the framework of the decrees of the President of the Republic of Uzbekistan for the Construction of the Ustyurt Gas Chemical Complex on the basis of the Surgil field with the development of the field (No.PP-797, No.PP-1168, No.PP-1594).
The field was first put into operation in 1998, exploration and drilling of wells was carried out by the enterprises of Uzbekneftegaz JSC. In 2013, the active phase of construction of the Uzbek-Korean joint venture Uz-Kor Gas Chemical began, the complex was built in three years, three months ahead of schedule.
ERIELL Group has been cooperating with Uz-Kor Gas Chemical from 2013 to the present day. At the end of 2020, ERIELL Group completed work under Contract No. 19E-1 dated 04.07.2019. to complete overhaul of 100 wells. In fact, 113 wells were completed ahead of the contractual deadlines for a whole year.
As part of the new contract, from 2021 on the bottom of the Aral Sea in the Muynak region of the Republic of Karakalpakstan, multidisciplinary workover will be carried out with the development of its own coiled tubing unit. Preparations have begun for pilot work on a new technology in Uzbekistan - "Radial drilling". Radial drilling is a new technology in stimulation of oil and gas wells, which allows reaching a more distant part of the productive formation from the well. In addition, using the core sampled from the field, work is underway to select an acid mixture for further use in the treatment of the bottomhole zone of wells in the field. We also discussed with the customer a plan for hydraulic fracturing (hydraulic fracturing) using our own fleet and qualified specialists.
In total, at the Surgil field, the ERIELL Group completed the construction and commissioning of 85 wells, and 184 wells were overhauled. Since September 2015, all products from the gas wells of the field have been supplied to the Ustyurt Gas Chemical Complex, built by Uz-Kor Gas Chemical. The complex consists of 5 plants: a gas separation plant, an ethylene plant, a polyethylene plant, a polypropylene plant, and an energy supply plant.
