... passage diameter is 57 mm (2.24"). Additionally, two techniques of ESP installation into sidetracks have been developed ( Figures 5 and 6 ). The first technique involves direct flushing with discharge of the fluid through the annulus to prevent friction. The second technique involves using a combination...

... wells is the fishbone well, which is a multilateral well with the main wellbore and a few sidetracks (ribs). Depending on geological objectives, the sidetracks may be drilled within the same geological object as the main borehole, or a different geological object may be targeted. While drilling...

...-, and five-lateral well designs were evaluated. As a result, based on economic feasibility and minimization of technological risks, a four-lateral well design was choosen. Drilling of these type of multilateral wells requires greater flexibility in changing the actual profiles and sidetrack depths, taking...
