ELASTIC, MICROSTRUCTURAL AND GEOCHEMICAL CHARACTERIZATION OF KEROGEN MATURITY FOR SHALES
… The dissertation links geochemistry, seismic and petrophysics. The experimental part of the dissertation involves rock-eval pyrolysis, TOC estimation, and anhydrous pyrolysis for artificial maturation, kerogen isolation, porosity and ultrasonic measurements on shales and kerogen. It also involves …

Geophysical properties of carbon monoxide when used as an enhanced oil recovery agent
ABSTRACT Many reservoirs witness decreased production related to the mobility of hydrocarbons given the composition of the fluids and rocks, and the reservoir environment (ie: temperature and pressure). Enhanced oil recovery (EOR) efforts attempt to manipulate these conditions to reach profitable …

Petrographic and petrophysical characterization of the Eagle Ford Shale in La Salle and Gonzales counties, Gulf Coast Region, Texas
The Eagle Ford Shale is an organic-rich marine carbonate-dominated mudrock located in the Gulf Coast Region, Texas. This mudrock was deposited during the Late Cretaceous and is composed of two main members: the lower and the upper Eagle Ford, which are associated to marine transgression and …

Approaches to Fines Production in the Walloons Subgroup, Surat Basin, Queensland
This study characterises the root causes for fines generation in coal seam gas wells in the Walloons Subgroup of the Surat Basin, southeast Queensland, Eastern Australia. Fines production can be critical in causing erosion in downhole pumping equipment and disruption to surface facilities. The …

Wettability assessment using resistivity and NMR measurements
The wettability of reservoir rocks influences multi-phase fluid flow and rock physics measurements. This impacts the relative permeability, recovery factor, choice of enhanced oil recovery method, and reservoir characterization. Wettability can be assessed using contact angle measurements and the …

Mechanical Stratigraphy of the Mississippian in Osage County, Oklahoma
<p>The Mississippian formation of Oklahoma and Kansas has recently developed as a world class unconventional reservoir with wells producing up to 800 bbl/day. The Mississippian is composed of multiple distinct lithologic zones including limestone, hard chert, and soft tripolitic chert. These zones …

Reservoir quality and well performance analysis in the middle member of the Lewis shale, greater Green River basin, Wyoming
impacting their habitat and reproduction areas. The Wyoming Game and Fish Commission published some recommendations to lessen the impact of oil and gas development on the wildlife to mitigate these effects (WG&F, 2007). These efforts include buffers around nests, migration corridors, concentration …

Integrated geological and petrophysical investigation on carbonate rocks of the middle early to late early Canyon high frequency sequence in the Northern Platform area of the SACROC Unit
The SACROC unit is an isolated carbonate platform style of reservoir that typifies a peak icehouse system. Icehouse carbonate platforms are one of the least well understood and documented carbonate reservoir styles due to the reservoir heterogeneities they embody. The current study is an attempt to …

Quantification of rock fabric through multi-scale image data analysis for enhanced rock typing and formation evaluation
Spatial variation of rock fabric (i.e., spatial distribution of minerals, pores, and saturating fluids) affects the estimation of petrophysical, mechanical, and compositional properties of sedimentary geological formations. Quantification of rock fabric and its integration with rock classification …
