ارزیابی پتروفیزیکی مخزن بنگستان میدان نفتی بینک

Petrophysical characters of different zones in Bangestan reservoir of Binak oilfield has been studied. For this Neutron, Gamma, Density and PEF logs along with lithological columns of the Bangestan reservoir wells have been used. Stratigraphical longitude cross section of the oilfield have been drawn using Column of seven wells out of total ۱۴ wells of the oilfield. Zonation of the studied reservoir was done on this cross section.It has been devided into ۷ zones, comprising  Ilam, Lafan and Sarvak Formations. In Later stage petrophysical characters of the divided zones, were extracted from the well reports and arranged in seven tables and finally ۹۸ maps of ۲D and ۳D were prepared. Main pay zones comprise, zone ۳,۴ and ۵. Among these, zone ۴ contains sufficient amount of Rudist debris and therefore has high porosity is the best payzone. Despite low primary porosity in whole oilfield, fractures especially at the crest(demonstrated by high mud lost), made Bangestan reservoir a good and productive reservoir. Maximum production from well number ۲ also, proves the determined results. Finally it could be concluded that the best location for future drilling would be north to northeast of well ۹, while perforating the zone ۴ of the drilled well.
