OREANDA-NEWS. Radial drilling technology tested on a well in Barsukovskoye oilfield.

The first results have shown that the efficiency of the well was enhanced. Last year this unique Belarusian technology of hard-to-recover reserves stimulation and development was tested on a total of six wells of Belarusian deposits. During such operations, filtration channels of up to100 metersin length are made from the casing string in the producing zone perpendicular to the axis of the well. This allows to enhance the drainage zone in tight reservoirs and improve the wellbore area permeability.

Pilot tests of this method were carried out using the complex equipment designed by engineers of the BelNIPIneft Department for Innovative Solutions Development and Belarusian Company Novinka. Radial drilling complex includes mini-coiled tubing unit and downhole assembly.

In accordance with Belorusneft Coiled Tubing Technologies Development Program, operations are to be performed in 2015 for enhancement of multilateral wells, geophysical surveys, as well as pilot tests of technology for creating a system of deeply penetrating filtration channels are to be continued on five wells of Rechitskoye, Tishkovskoye, Borisovskoye and Nadvinskoye oilfields.
