Keywords: offshore field, thin oil rims development, poorly explored deposits, extended horizontal wells, production profile calculation

Annotation:

At present, there are less and less deposits with easily recoverable reserves due to their gradual depletion. Due to this fact, such objects development is losing their relevance, while more and more attention is being focused on the development of deposits characterized by a low degree of study and a large proportion of contact reserves. Such deposits include deposits with thin oil rims.

The location of offshore fields imposes additional restrictions on their development caused by the low degree of study due to geological exploration economic reasons as well as the absence of a trial operation period.

Based on the accumulated experience in the offshore fields development of the Russian shelf, in the course of this article, the development systems by extended horizontal wells were formed for one of the uplifts of a multi-layer oil and gas condensate offshore field and the production profile for them was estimated.
