Wellsite Geology Fundamental

The wellsite geologist acts as the link between the drilling supervisor, rig personnel and the company's office. As such, his responsibilities incorporate all geological activities on the rig. One of his main duties is to obtain as much geological information of the drilled well as possible and report that information in a clear way. After completing this course, the participants will be able to perform the basic well site geological duties.

Graduated Geologists, Geoscientists and petroleum engineers.


16 years in the world of wellsite geologist / operation geologist with extensive oil and gas field experiences in Indonesia and overseas and has been working on several onshore and off-shore rigs to the deep water in various projects of development, delineation, and exploration - wild cat wells. Several challenged drilling environments were also part of learning that adding value of the experience as a wellsite geologist, such as: - Wellsiting in over pressure, high pressure and high temperature (HP/HT) gas wells as well as depleted reservoir hazards in Mahakam block gas fields and Sanga-Sanga block. - Wellsiting in highly deviated and horizontal geosteered wells in some development projects such as in Sanga-Sanga Block, Gulf of Thailand, Malaysia basin, and Angola offshore in southern part of Atlantic Ocean. - Some exploration and wild cat wells in Arafura Sea, Makasar Strait, Vietnam Off-shores in South China Sea, Hong Kong off-shore in P.R China with various sediment environment such as Deltaic system, single channel reservoir, carbonates rocks, and Paleozoic rocks objective, etc. - Several development wells in South Sumatra Basin.
