Prospects for the use of new technologies in assessing the impact of geological and technological risks

摘要: Nowadays, operator companies pay much attention to the introduction and development of technologies for oil fields using horizontal wells. This situation is due on one hand relatively greater efficiency operation wells, as compared with vertical, problems typical wells (low share 10-30 % "working" part well, specificity influence heterogeneity reservoir during stimulations, difficulty water source control other hand. In addition, it necessary take into account a number factors causing exclusive use wells: restriction location wellhead relative target areas reservoir, highly viscous super-viscous oils, unconventional (dense) reservoirs. The main objective this work determine prospects application new increase It impossible describe full picture without reflecting results analysis performance in field development, planning investments drilling well considering aspects economic evaluation designed improve Much paid identifying causes declining production premature irrigation Various options occurrence flow their reservoirs are considered.
