Well Log Interpretation
The course is designed for those to broaden their skills in the formation evaluation/Petrophysical Analysis discipline. Geoscientists, operation geologists, petrophysicists, reservoir engineers, and petroleum engineers. Others are very welcome.
Objectives:
- Understand the spectrum of technology and subsurface data set related to Petrophysical Analysis with focusing on tool physics, advantages and limitation including onsite formation evaluation, wireline logging and core analysis applications.
- Deep Learning characteristics of clastic and carbonate reservoirs mainly to address factors controlling reservoir quality.
- Learn about wireline log record include tool specs of basic log, advantage and its limitation, application to perform petrophysical analysis.
- Perform an integrated petrophysical analysis by combining geological knowledge of various reservoirs, core analysis with elements on petrophysical analysis and available data set.
- Able to recognize reservoir quality and potential pay zone by using all the available data sets that applicable in daily basis work

3 days
Fondation
Classroom
DAY 1
- Familiarization to onsite formation evaluation gas reading, gas chromatography, cutting and oil show descriptions to recognize reservoir quality and potential pay zone.
- Understand Clastic Reservoir to reveal reservoir quality and possible reservoir geometry and its distribution. The topic will include depositional environment and factors controlling reservoir quality, clay type and its distribution in reservoir.
DAY 2
- Continue learning Clastic Reservoir
- Characteristics of Carbonate Reservoir will deal with the depositional environment, mineralogy and diagenesis that led to its pore geometry and distribution complexity. Heterogeneity will be discussed intensively.
DAY 3
- Acquisition of standard wireline log including operational matter, resolution and environmental correction.
- Fundamental concepts for petrophysical analysis including formation temperature,
- Explanation of basic logging include gamma ray, spectral gamma ray, resistivity, density and neutron log. Discuss about tool specs, advantage, limitation and application to calculate shale volume, porosity and water saturation.
DAY 4
- Continue on wireline log acquisition and interpretation
- Introduction to core analysis workflow, routine core analysis and its application to characterize reservoir and calibrate log interpretation (porosity, permeability, Sw and possible Rock Typing)
- Continue on integration petrophysical analysis and study case for open discussion
Our Trainer is a freelance consultant geologist with experience in the oil and gas industry for more than 30 years focusing on formation evaluation and reservoir characterization disciplines with various fields and companies. On some occasions, he has given a short course of formation evaluation for geological students in some Universities in Indonesia since 2002.He graduated from Geological Engineering UGM (1991). The following is a brief of his working experience. He was a mudlogger (Exlog. -1991), Wellsite and Operation Geologist (Asamera Oil / Gulf Res / COPI – 1995), Senior Operation Geologist (Hess Indonesia, – 2003). Team Lead Geological Operation ( Petronas Kuala Lumpur, – 2004). Senior Petrophysicist (Hess Indonesia, – Mid 2006), Chief of Development Geologist and Geophysics (PHE WMO, – 2014), Advisor Geology (PHE WMO, – 2016), Advisor Geology (PHE Subsurface Development / Innovation, 2018 – 2022 retired).
