OAO Varioganneft introduces discrete gas lift technology at the fields of Variogan oil block.

Raduzhny, KhMAO. OAO Varioganneft introduces discrete gas lift technology at the fields of Variogan oil block. The first well where this method was used is being tested at Tagrinskoye oilfield.

The expected average flow rate increment at well No. 30076 Pad 6a makes up 3 tons per day. Varioganneft applies discrete gas lift technology at the field with high gas factor. Discrete gas lift technology is based on using the energy of APG of the oil well. The fluid is lifted to the surface by creating the pressure difference  between lower and upper ICVs. This happens while the fluid is being gathered in tubing. When the pressure created by the ICV settings appears the fluid column rises up to the surface by means of gas expansion which comes into tubing within the last working cycle of the controller. This new technology will allow to increase the oil production, extend the time period between the well maintenances, and decrease the power costs as well as to reduce the number of equipment failures at the wells with high gas factor. OAO Varioganneft will continue to apply the discrete gas lift technology at the fields of Variogan oil block, the press-office of the company reported. Implementation  of the programs  of introducing new technologies at the oilfields of AO NK RussNeft subsidiary will allow to form the stable tendency of hydrocarbon production increment factors
