Duration:
5 half-day sessions online (or 3 full days F2F classroom)
Business context
Throughout the exploration cycle, from play-based exploration to prospect maturation, from near field exploration to appraisal, a sound geological knowledge of basin type, sediment-fill, and deformation phases, should underpin the regional play and detailed prospect specific mapping, modelling and subsequent risk and volumetrics work.
Based on the trainer's experience of NW Borneo hydrocarbon exploration and development, extensive use of outcrop analogues and relevant subsurface analogue data, the course aims for delegates to acquire knowledge not only on SE Asian basin settings, but also how their petroleum systems work. The subsequent petroleum geological focus is on reservoir/seal distribution as well as regional deformation phases and trap formation.
The course will make use of seismic, log and core data, but it will also make ample use of NW Borneo's first-class outcrops as analogues to the subsurface. Seismic stratigraphic principles underpin the Petroleum Geological evaluation.
Where relevant, sediment petrographic data and principles will be used to invoke reservoir effectivity discussion.
Who should attend
The course is aiming at geoscientists working on play-based exploration and prospect generation / maturation projects as well as near-field exploration / appraisal.
Course content
The course will be delivered as a 5-session (half days) VILT course, or as a 3-day classroom F2F course.
The approach this course takes is geological rather than tool focused.
Tectonic Evolution of Southeast Asia.
Overview of the petroleum systems and petroleum geological characterization of SE Asia basins.
Discussion of structural setting information and basinfill analysis based on seismic stratigraphy, log facies, core, and outcrop data.
A virtual reality field trip to outcrops linked to the NW Borneo Miri Oilfield case history.
Examples / Case histories include:
Indonesia's Kutei (Kalimantan) and South Sumatra Basins
Vietnam's Cuu Long and Nam Con Son Basins
Malay Basin
South China's Qiongdongnan Basin
Philippines' Palawan Basin
NW Borneo
Most case histories derive from NW Borneo Hc Provinces, Hc Plays and oil / gas accumulations.
Discuss reservoir / seal and structure of Baram province oilfields using northern Sarawak clastic outcrops as analogues including the onshore Miri Oilfield and a virtual reality fieldtrip to a Miri Hill outcrop.
The Sarawak Luconia Carbonate province gas-play and fields.
The large deltaic growth-fault oil/gas fields in Brunei and Sabah.
The DW oil and gas fields of Sabah deep water.
Labuan Island and KK area (Sabah) deep water outcrops are used as direct analogues.
Learning, methods and tools
The course makes use of data such as seismic, log, core, outcrop, and satellite images.
Method of teaching consists of a mix of lectures and hands-on exercises, while stimulating individual, team, and plenary discussion.
