Sidetracking is performed from an open wellbore from an installed hollow, non-retrievable whipstock. Both wellbores are equipped with liner filters.
stable rocks where sidetracking is problematic without a whipstock
multilateral wells of the “Fish skeleton” type.
2 trips to set up the system (basic algorithm)
Available option – rotating liner run (17 kNm)
The ability to flush the well during the run through special holes in the whipstock;
Main wellbore production is maintained thanks to the design of the TAML 1 ML One multilateral completion system
The developed equipment makes it possible to replace the well fluid with a breaker to dissolve the filter cake, which increases the efficiency of well operation with a filter end.
High expansion coefficient of the anchor allows for reliable installation of the system in an open hole
High accuracy and the ability to duplicate orientation methods without involving the MWD telemetry service. The maximum error of the equipment used is 3 degrees;
The unique design of the production whipstock (rate of curvature gain – 1.75 ° / 30m) makes it possible to use the RSS layout for further sidetracking
Hydraulically activated sidetracking system (no cement plug)
