Concepts of Deterministic Petrophysical Rock Typing for Reservoir Characterization with VILT
Concepts of determininstic petrophsyical rock typing is an essential component of reservoir petrophsyics and characterization. This course is designed to delivered using VILT (virtually instructor led training) and delivered in real time. The course will be taught in 4 hour sessions over a 3 day period and is delivered using the WebEx or similar platform”
This course enables participants to understand the fundamental concepts applied pore geometry based methods using porosity, permeability and mercury injection capillary pressure analysis to determine petrophsycial rock types. Common petrophsyical rock type (PRT) methods such as Winland, Leverett, Pittmann, FZI and RQI are discussed during the course. Participants, compare the predicted pore throat radius and petrophysical rock type to well log based water saturation in depth space and cross-plot analysis.
Participants are introduced to statistical methods to determine the number of PRT needed for a well analysis.
Participants complete a concept workshop using Excel, so the process is transparent to the users.
