AWALI FIELD VISIT

ORGANISER

Tatweer Petroleum

OVERVIEW

Awali Field was the first field to be discovered in the Arabian Peninsula in 1932. Located 30 km south of Manama, the field continues to be a significant contributor to the local economy. It is a geologically complex field, measuring approximately 15 km long and 5 km wide and includes sixteen stacked oil reservoirs and six gas reservoirs located with in more than six thousand meters of stratigraphy.

The field visit will cover outcrops around the Jebel Al Dukhan area, the surface expression of the Awali anticline, where Eocene Dammam and Rus carbonates are exposed as a series of small Jebels and rimrock cliffs and are surrounded by younger Miocene and Quaternary deposits on the periphery. The one-day visit will give participants an overview of the structural history of the island, facies architecture and evidences of geomorphological processes active on the field. It will also cover present day oil and gas infrastructure in the field and the BAPCO Oil museum.

FIELD STOPS

Jebel Area

  • Series of small Jebels where main features of the Awali anticline can be observed along with outcrops of the Eocene Rus group
  • Mineralized fault: representing the main faulting trend of the Awali anticline central graben
  • Interior basin Rus group pavements

Facilities Stops

  • Overview of the main infrastructure on the field
  • Water Treatment Plant: receives liquid production from surrounding manifolds for further separation where oil and water gets separated through series of separation methods both physical and chemical assisted separation. The separated high quality water is then injected back to the reservoir
  • Gas Compression Station: established to compress associated gas produced from WM up to adequate pressure for re-injection into the reservoirs
  • Steam Generation Station/Pilot where treated water is pumped to the steam generation facility to produce steam for steam injection

Quarry Area

  • Rimrock forming the internal slope of Awali structure
  • Cyclic deposition of the Eocene Dammam deposits and recent sandier deposits can be observed

Tree of Life

  • Site of cultural and archaeological importance

Dar Al Naft

  • Well No. 1 First discovery well in Arabian Peninsula drilled in 1931
  • Dar Al Naft: Small hall displaying historical items and archive photographs related to the history of the petroleum industry in Bahrain

PHYSICAL EXCURSION AND WEATHER CONDITIONS

The amount of physical excursion is low to moderate. Certain outcrops would require walking around and gentle climbs. Walking shoes, hats and weather appropriate clothing are recommended. Weather during February can be expected to be clement with moderate to warm temperatures.
