Understanding Sub-Surface Pressures
21st October 2019 - 23rd October 2019
This course is practical in nature, revolving around the elements of pressure plots, data to populate them (e.g. RFT/MDT and LOT/FIT) and their interpretation, and an exploration of how to conduct useful pressure prediction/detection (both pore pressure and fracture pressure). The course covers topics such as the origin of abnormal pressures in the subsurface, seal breach, seal capacity, hydrocarbon column height and hydrodynamic aquifers. There is a mixture of lectures, discussion and exercises. Day Three will include sessions covering pore pressure issues as they relate to SE Asia geology, and where drawing examples and case material from where the course participants come dominantly located.
Who Should Attend
- Personnel preparing for future drilling, but also for the ability to incorporate pressure data and concepts into operations and future exploration programmes. Appreciation of pressure prediction methods and their uncertainties pressures is also needed by management, especially when the company operates in high-risk environments, such as HPHT and Deep-Water.
Key Learning Objectives
- To explain the relevance of pressure interpretation in exploration/production/drilling
- To offer insights into the relationship between pressure and subsurface geological conditions, including mechanisms which create abnormal pressures, and the role of lithology in maintaining and distributing excess pressure
- Summary of the challenges of high pressure sediments, with particular reference to all types of tectonic environments including thrust belts
- Link throughout the course, where relevant, to subsurface challenges in SE Asia, especially Malay Basin, offshore north Borneo (Sarawak, Brunei and Sabah), Mahakam Delta and Gulf of Thailand
