Abstract
In the modern world, in large fields with extensive gas caps, oil rim development is associated with the issue of gas breaking through from gas caps to the bottom of oil wells. Furthermore, this issue may also be aggravated by the limited capacity of associated petroleum gas disposal and/or transportation infrastructure. The article presents an analysis of the evolution of methodologies aimed at reducing the production of breakthrough gas from a gas cap by oil wells during the development of an oil rim of the Bt reservoir of the Botuobinsky horizon of the Srednebotuobinskoye oil and gas condensate field. To date, an effective strategy for the development of the under-gas-cap zone has been formulated, comprising the implementation of diverse technologies with the objective of reducing the gas-oil ratio. The experience of developing the under-gas-cap zone of the Srednebotuobinskoye oil and gas condensate field may prove instructive in the development of analogous fields exhibiting comparable geological characteristics.
