..., the image log indicated that the well was drilled through numerous, sub-seismic folds. Near the toe of the lateral, three distinct intervals separated by ∼30-40 feet were identified: (a) normal bedding (less-folded), (b) the presence of a fold structure, and (c) presence of a fold structure with fractures...

... Abstract The fine-scale lamination/bedding is an important feature commonly neglected in the characterization of unconventional reservoirs. Self-sourced mudstone deposits are frequently described as layered, or Vertical Transverse Isotropic (VTI) bodies, assuming the absence of significant...

... ratio and maximum dip angle relative to bedding. Our modeling results confirm that the compliance ratio is sensitive to fluid. Fluid-saturated rocks exhibit a lower compliance ratio than that of dry rocks, which is usually less than 1 and close to 0. This behavior is consistent with a fluid stiffening...

Results/Observations/Conclusions: The Caney Shale is rich in clay minerals (dominantly illite). We identified three mixed...

.... As maturity increases, the location of organic material will shift from predominantly load bearing, bedding plane parallel oriented laminae, to interparticle pores, as kerogen is thermally altered to bitumen. This results in distinct changes in the vertical acoustic velocity signal and in the observed...
