Petroleum Systems in Indochina
Summary
GETECH has performed a number of studies which examine the petroleum systems of the Thailand and the Gulf of Thailand Basins, Onshore Thailand, Offshore East Vietnam, Southern Indochina and Offshore Southeastern China. The studies build on GETECH's unique global gravity and magnetic data to underpin a re-evaluation of the structural development of the Indochinese Peninsula and implications for the tectonic development of the region. This forms the basis for the mapping of seven critical palaeogeographic and palaeolandscape timeslice reconstructions. Aided by an analysis of the modern day drainage, the studies then review the landscape evolution and likely effects on sediment dispersal. They also contain a review of the geochemical literature and new geochemical modelling. All these have been utilised to generate new insights into the petroleum systems of the Indochina region.
Basins studied:
- Malay
- Pattani
- Khmer
- Greater Thai Basin Province
- Khorat Plateau
- Onshore Tertiary Basin Province
The study concentrates on six key issues: the effect of the structural framework on the prospectivity of the area; the effect of palaeolandscapes on drainage and palaeoclimate; source rock facies variation and maturity; the distribution of reservoirs and the main controls on quality; and the main risks and rewards for oil and gas exploration in the region.
Basins studied:
- Khorat Plateau
- Onshore Tertiary Basin Province
This study is a subset of the larger Thailand and Gulf of Thailand Basins Study. It is designed to make our work accessible to companies that have recently gained onshore exploration acreage in the 2007 Thai 20th Concession Bidding Round.
Basins studied:
- Beibu Gulf
- Song Hong
- Phu Khan
The study examines: the kinematics of the South China Sea opening (including a new model for the development of the Song Hong Basin); the effect of landscape evolution on the Red River and the Mekong; source and reservoir distribution and variety; and the main risks for hydrocarbon exploration in the above basins including some data from the Qiongdongnan Basin as an analogue to CO2 development in the study area.
Basins studied:
- Cuu Long
- Nam Con Song
- Tonle Sap
The study examines the effects of opening of the South China Sea and the rotation of Indochina on the structural framework of the region; the main drainage features which have had influence on the offshore basins; the main source and reservoir horizons for the offshore basins; overall risks and potential of the hydrocarbon basins studied.
Basins studied:
- Beibu Gulf
- Pearl River Mouth
- Qiongdongnan
Our latest study revisits the Beibu Gulf and then extends our coverage along the margins of southeastern China with comments on development of the deeper offshore basins and the wider structural development of the region.
Deliverables
