Weekly seminar on February  11, 2015, 10.00 will feature a report  by PHD, Abbasov Elkhan Macid ogly, head of the Department “Design and optimization techniques exploit the wells” of Research  Project Institute Oil and Gaz ofSOCAR, entitled “Non-stationary filtration process integral simulation in horizontal wells ”.

Accounting for a well-reservoir system dinamic contact in horizontal wells and filter–type horizontal part of a pipe wall, non-stationary filtration process of water through reservoir was studied by mathematical simulation. Well productivity was defined depending on length of the horizontal part of a well and reservoir characteristics. With regard to filter-type horizontal part of a pipe wall and well-reservoir system dinamic contact, an analytical formula was found in order to determine pressure loss in a pipe. Wellbottom pressure history was determined. Based on studies, parameter values improving horizontal well producing characteristics was defined.
