Construction of wells of a special design for the production of extra-viscous oil


The company has experience in the construction of wells of a special design for the production of extra-viscous oil at the Ashalchinskoye field in the republic. Tatarstan. The drilling of such wells is carried out according to a special technology using machines with the possibility of drilling at an angle of 35-55 degrees. According to this technique, cluster drilling of paired horizontal wells is carried out, the horizontal wells of which are located one above the other in space. A well with an overlying wellbore is intended to be a steam injection well, and a wellbore with a downstream wellbore is a production well. Or the construction of a steam cycle well is envisaged, which will subsequently operate both in the steam injection cycle and in the production of extra-viscous oil.
