Challenge: Accurately determine the
proportion of movable liquid hydrocarbon to optimize and rationalize completion
decisions in an Eagle Ford reservoir.
Solution: Differentiate kerogen from
hydrocarbon by comparing kerogen-insensitive total porosity (TMCR) from the
CMR-Plus combinable magnetic resonance tool with kerogen- and fluid-sensitive
total porosity from the bulk density (PHID) computed using the corrected matrix
grain density provided by Litho Scanner high-definition spectroscopy
service.
Results: Confidently assessed reservoir
quality by subtracting the kerogen carbon content, derived from the PHID and
TCMR comparison, from the total organic carbon (TOC) determined by Litho
Scanner service to identify movable hydrocarbons and optimize the completion
design.
