Some Experience with Drilling and Use of Horizontal Wells and Way of Their Application in Croatian Hydrocarbon Reservoirs

Geologia Croatica, 2010
In many hydrocarbon reservoirs horizontal well paths enable the more economical extraction of oil and gas than with vertical wells in the same reservoirs. This is especially true for cases of by-passed oil in partially depicted reservoirs.

3D numerical simulation of clastic reservoir with bottom water drive using various ior techniques for maximizing recovery

Journal of Petroleum Exploration and Production Technology, 2018
In most reservoirs with oil rims, as the production begins, the gas–oil and oil–water fluid interfaces start deforming because of the imbalance between viscous and gravitational forces, leading to coning or cusping.
