چکیده
Production from this field was started 82 years ago and oil production at this field is from the extensive Cretaceous carbonate reservoirs. This field is located in the Southern part of Iran, withtwo carbonate reservoirs, Asmari reservoir on the top and Bangestan the bottom. At the present, out of 65 drilled wells, 6 wells are completed directionally, and other wells are vertical. In this paper the productivity of Horizontal and directional wells is studied. For this reason, one well isselected and all steps of evaluation is disscussed. Production results from deviated wells are more acceptable than vertical ones, and in most cases productivity index of deviated wells is equal ormore than vertical wells. The flow rate of deviated wells are higher than vertical wells and withrespect to the geological structures and low oil column thickness there was a need to drill horizontal and directional wells. The objectives of this study are to gain a better understanding ofthe reservoir, its production performance and horizontal well performance. In this study afterevaluating well testing results the well model is created and then sensitivity studies on different parameters for the deviated wells at inflow and outflow of the system is also discussed.کلیدواژه ها
