Proceedings Papers

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 20–22, 2022
Paper Number: URTEC-3708626-MS
... Abstract Objectives/Scope Subsurface scales include scale deposits present at downhole, in or near perforations, in fractures, on fracture proppants/frac faces, in porous media near frac face. As fractures and frac faces provide key pathways for hydrocarbon production in shale & tight...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, July 22–24, 2019
Paper Number: URTEC-2019-561-MS
... Abstract Hydraulic fracturing fluids (HFF) for unconventional shale reservoirs are formulated to maximize productivity, however, much remains unknown about the fundamental reactions involving HFF additives that occur upon injection into the subsurface. We studied reactions between surfactant...

... Abstract The objective of our research is to reconcile the differences, in both age and relative stratigraphic position, between the Woodbine and Eagle Ford Groups in the outcrop and subsurface of the East Texas Basin. In the outcrop belt, organic- and carbonate-rich Middle Cenomanian mudstones...

Paper Number: URTEC-2902629-MS
... Summary Although sand proppant has been used since 1949 to increase efficacy of hydraulically fractured treatments by preventing fractures from closing after well depressurization, many questions remain regarding the behavior and distribution of proppant in the subsurface. To this end, we...

... for the VM Formation in the hydrocarbon-producing basin center where outcrop and subsurface show a nearly uniform formation thickness. Key log-signature subdivisions from the subsurface correspond to sequence stratigraphic divisions identified in the Puerta Curaco outcrop. TOC, Spectral gamma ray...

..., and in general any small scattering objects, by using Diffraction Imaging as a complement to the structural images produced by reflection imaging. Diffraction Imaging is the imaging of discontinuities in the earth. Diffractions are the seismic response of small elements (or diffractors) in the subsurface...

Paper Number: URTEC-2154599-MS
... Summary Often one of the most basic challenges of using outcrops to better understand the subsurface is simply terminology. These terminology challenges include: 1) provincial outcrop nomenclature; 2) the fundamentally different way stratigraphic units are commonly defined in the subsurface...

... for measuring petrophysical properties relevant to natural subsurface cores is not suitable. This problem created during hydrous pyrolysis is alleviated by using a stainless steel uniaxial confinement clamp on rock cores cut perpendicular to bedding fabric. The clamp prevents expansion just as overburden does...

Paper Number: URTEC-1580135-MS
... Summary Economic production of oil and gas from mudrocks such as the Devonian Marcellus Shale relies on hydraulic fracture stimulation. The orientation, size, porosity, and strength of subsurface natural fracture systems can influence the growth of hydraulic fractures by conducting fluid...
