ACE SC 4 | Rock Properties Modeling from 2-D Images: Making the Most of Thin Section Image Data
American Association of Petroleum Geologists (AAPG)
Saturday, 6 June 2020, 9:00 a.m.–5:00 p.m. | Houston, Texas
Who Should Attend
Geologists and Petrophysicists working with subsurface core and log data
Objectives
To illustrate the utilization of 2-D image data and image analysis for modeling important rock properties including: absolute permeability, geomechanical properties (pore volume compressibility, peak strength), strain analysis and anisotropy, and acoustic properties.
Course Content
Any complete core analysis program should include companion thin sections for all core plugs on which measurements have been made. Quality control of core plug measurement data is facilitated by examination of a companion thin section. For example, thin section porosity from image analysis should be nearly equal to core plug measured porosity (when including a correction for microporous phase volumes). Reflected, and fluorescent light, and Raman imaging and measurements are used to estimate thermal maturity in unconventional reservoirs and to make inferences regarding organic matter type. Cathodoluminescence imaging aids in the differentiation of authigenic and detrital phases. This course will describe the use of multimodal thin section imaging and image analysis to make quantitative estimates of rock properties that are important in hydrocarbon exploration and production.
