Paper Number: URTEC-3848882-MS
... Abstract Organic-rich carbonates from the Upper Cretaceous period in southeastern Turkey are recognized as major unconventional hydrocarbon source rocks. A workflow for derisking the productivity of an unconventional play involves examining the S1 X 100/TOC ratios, which represent potentially...

Integration of wireline logs and seismic data can help in estimating dominant production factors such as: fluid properties (porosity, saturation, total organic carbon, etc.), pore pressure spatial variability, and geomechanical properties (Poisson's ratio and Young's modulus). Our...

In this study, 12 samples from the Permian basin with a wide range in Total Organic Carbon (TOC: 0–7 wt.%) and carbonate (5–87 wt.%) were selected. Each sample was divided into two companion specimens: one...
