... Abstract An immature sample from the Bakken Formation was subjected to anhydrous and hydrous pyrolysis (AHP/HP) testing over a temperature interval from 300°C to 450°C to examine the potential variations of byproducts using biomarker geochemistry, organic petrology, and chemical composition...

...-member that was deposited under invariant depositional conditions, a modified version of open-system hydrous pyrolysis (OSHP) has been developed. The design of this artificial maturation apparatus differs from previous designs in that a small continuous flow of only liquid phase water is maintained...

... Summary Low-temperature hydrous pyrolysis (LTHP) at 300°C (572°F) for 24 h released retained oils from 12- to 20-mesh-size samples of mature Niobrara marly chalk and marlstone cores. The released oil accumulated on the water surface of the reactor, and is compositionally similar to oil...

... produced hydrocarbons, but also influences many petrophysical properties. Lacking a spectrum of source rocks at spanning the observed range of maturities found in shale plays, hydrous pyrolysis can be used to emulate the natural maturation process and its products. However, the original experiments...

...), and vitrinite reflectance. Samples were processed using hydrous pyrolysis. Rock residues were examined to evaluate the effect of the increasing temperature on the chemical, mineralogical, and petrographic properties as the samples transitioned from thermally immature to mature to post-mature (gas window...

... at different thermal maturities is seldom possible. An alternative approach is to induce thermal maturity changes by laboratory pyrolysis on aliquots of a source-rock sample of a given facies of interest. Hydrous pyrolysis is an effective way to induce thermal maturity on source-rock cores and provide expelled...

... confinement clamp was used on Woodford Shale cores in hydrous pyrolysis experiments to limit sample expansion by simulating the effect of overburden present during thermal maturation in natural systems. These samples were then subjected to X-ray computed tomography (X-CT) imaging and low-field nuclear...

... Summary A uniaxial confinement clamp was used on Woodford Shale cores in hydrous pyrolysis experiments to study fracture development during thermal maturation. The clamp simulates overburden in that it prevents cores from expanding perpendicular to bedding fabric during the volume-increasing...
