For the first time in Ukraine, DTEK Neftegaz used depth video cameras to inspect the wellbores of the existing well stock in real time. The pilot project is being implemented in cooperation with the international contractor Weatherford.
The oil and gas business DTEK, as part of a pilot project, tested deep chambers at the wells of the Semirenkovskoye field to determine the causes of obstruction during geophysical surveys. DTEK Neftegaz is implementing the project together with the international service company Weatherford, which acts as a contractor for lowering cameras into wells. The supplier of DHVI video cameras is Symoil. The chambers can be used in extreme conditions - at pressures up to 1000 atmospheres and temperatures up to 150-160 ° С. This allows them to be used for surveying wells over 5000 meters deep in real time.
The use of deep video cameras allows you to accurately determine the cause of obstruction along the wellbore. When applied to the wells of the Semirenkovskoye field, DTEK Neftegaz reduced the time required for eliminating wells from obstruction by more than 75% and reduced the cost of work by 40%. The use of video cameras significantly increases operational efficiency, reduces well downtime and helps to increase gas production.
“DTEK Oil and Gas used deep cameras for well survey for the first time in Ukraine. The cameras have demonstrated their effectiveness at the Semirenkovskoye field, and the company plans to use them in the future. Thanks to DTEK's oil and gas business, Ukraine attracts the latest global technologies that have never been used in the national oil and gas industry before. This contributes to the development of gas production and strengthening of the country's energy security, "said Igor Shchurov, CEO of DTEK Oil and Gas.
