A ring R is right PF if it is right self-injectine and right cogenerator. In this paper, the authors show that a R ring is right PF if and only if R has right finite Goldie dimension and it is right cogenerator
if and only if it is right QF2 and right cogenerator.Viện Dấu khí Việt Nam (VPI) đã tích hợp các kết quả phân tích mẫu thạch học, mẫu lõi, phân tích ảnh thành hệ (FMI) và minh giải tài liệu địa vật lý giếng khoan để làm rõ đặc trưng của đá chứa carbonate khu vực mỏ Bắc Oshkhotynskoỵe, Liên bang Nga.

In this area, carbonate reservoirs were deposited in warmly shallow marine environment with blue-green algae and stromatoporoid in Devonian formation. These carbonate reservoirs experienced multiple diagenetic processes such as cementation, recrystallisation, dolomitisation or dissolution which affected the poroperm properties of reservoir rocks. The quality of carbonate reservoirs in the North Oshkhotynskoye field is rated from average to good with mainly interparticle porosity, fractures and vugs. The paper divides the carbonate reservoirs in the North Oshkhotynskoye field into three types: Type 0 - tight carbonate reservoir, Type 1 - interparticle carbonate reservoir, and Type 3 - vuggy carbonate reservoir, to support the building of structural model in the next study process. Currently, oil has mainly been produced in this carbonate reservoir of the North Oshkhotynskoye field with cumulative oil production from 2015 to 2018 reaching more than 700.000 tons.
