The paper considers new approaches to further development of mature gas-condensate fields, which are aimed at the maximum recovery of in-place reserves using the systems of horizontal wells. The gas-hydrodynamic simulations on the sector model of a depleted field were performed.
Analysis of geological features of the fields of Uzbekistan is crucial to the planning of horizontal wells. As an example of how geological features are taken into account for effective further development of the fields, the reservoirs of Amudarya oil-and-gas basin are described.
The questions of geosteering, well targeting along the formation and optimum completion of horizontal and multilateral wells, including with the use of inflow control devices, are addressed.
Studies found the appropriateness of the operation of horizontal wells in comparison with vertical wells, which have several technological and economic advantages, such as the cost of such wells, simplified system of surface facilities, production rate as fraction of in-place gas reserves.
