Professionals of TATNEFT Company continue implementation of the contract for rendering services to enhance oil recovery in the south-eastern part of production shop No.4 of NGDU Goturdepeneft in Turkmenistan. Over 13,000 tons of crude oil have been additionally produced from the wells put into operation.

 

The purpose of the contract is to bring in new equipment and technologies, proven in the fields of JSC TATNEFT, for increasing crude oil production in the wells of Goturdepe oilfield.

 

The active phase of workover operations and bringing of wells back into operation began in February 2012. Tatneftesnab’s administration organized delivery of equipment and materials. Totally, equipment and materials valued for more than $8 million were imported in Turkmenistan.

 

9 wells have been put in operation since February 2012 for the purpose of increasing oil recovery. Currently, the average daily production has exceeded 50 tons. Workover operations are carried out by workover crews of JSC TATNEFT's branch in Turkmenistan.

 

A production and utility base has been set up and commissioned to date at Goturdepe oilfield. 100 new jobs have been created, including 70 recruited Turkmen specialists. A system for monitoring the operation of existing wells has been deployed with application of the automated system. Teamwork of two workover crews manned by professionals from Tatarstan and Turkmenistan has been organized.

 

The wells stock in the south-eastern part of Goturdepe oilfield is complicated with high gas/oil ratio, accumulation of wax in the tubing string, sanding-ups, corrosive crude products, nonstandard well designs and a variety of complications during downhole equipment operation, as well as a complex tectonic structure of oil-bearing deposits with the presence of geological faults.

 

JSC TATNEFT has a wide range of various technologies, equipment and experience to solve the above-mentioned problems, including sidetracking, application of coiled tubing units, application of plaster patches for insulation of production string defects, etc. These technologies are planned for application in the further implementation of the contract.
