MINING PREPARATION OF OIL FIELDS OF SHALLOW-LYING VISCOUS OIL FIELDS

Neft i Gaz, 2023
In this paper, the idea of combining the experience of mining and oil production with the possibility of using gravity forces to extract oil is considered. It provides for the sinking of mine workings and wells that contribute to the outflow of oil down into the mine workings, thereby eliminating the resistance of gravity forces to the extraction of ...

Oil/Water Separation Experience From a Large Oil Field

SPE Production & Operations, 2005
Summary This paper discusses challenges related to emulsions that have been encountered in a large Saudi Arabian field. The field produces from several different reservoirs with a range of fluid properties. These properties provide an interesting case of operational challenges in oil/water separation, including increased incidents of ...

Rumanian Oil Fields

AAPG Bulletin, 1925
Abstract The distribution of the Rumanian oil fields is governed by lines of folding related to the major Carpathian overthrust faulting. Along these lines of folding, the production tends to focus around salt masses that form local “highs.” The source of the salt is unknown. Its rise is due to lateral pressure.

Ramadan Oil Field

AAPG Bulletin, 1991
Ramadan oil field, located in the central Gulf of Suez, is one of the giant oil fields of Egypt. It is named for the Islamic month of Ramadan during which it was discovered through the drilling of the well GS303-1 in September of 1974. Production comes primarily from within the massive sandstone reservoir of the Nubia 'C' Formation which covers some 2 ...
