TAML 1 multilateral well completion system is the simple and widespread technology which applies to both new and old wells. TAML 1 design provides permanent lateral access.
Sidetracking is performed from the open hole using the production non-retrievable whipstock. The last one ensures production from both wellbores.
Flexibility of TAML 1 allows to address a wide range of issues. There is contracting trilateral (and more) wells, reduce the number of RIH, optimisation of the operation within one trip, etc.
Stable f ormations
sidetracking is problematic without whipstock installation
Fishbone multilateral wells
Wells combined design
construction of several cased and open hole wellbores
2 trips to install the entire system – basic scenario
High accuracy of orientation methods
(3 degrees) without involving the MWD telemetry service;
The unique design of the production whipstock makes it possible to use the RSS BHA for sidetracking
The developed equipment makes it possible to replace the well fluid with a breaker to dissolve the filter cake, which increases the efficiency of production
