Challenge: Evaluate rock and fluid
heterogeneity along the lateral of a well in the Marcellus Shale.
Solution: Assess fluid and formation
heterogeneity and obtain thermal maturity proxy at surface with isotope logging
service providing continuous measurement of the isotopic ratio.
Results:
- Provided a thermal maturity log that showed strong agreement with the
official Marcellus vitrinite reflectance equivalent (VRE) map and that was
confirmed by a separate study
- Confirmed homogeneity of the fluid maturity and the formation
- Enabled optimal development of unconventional reservoir
