Capillary pressure curve and liquid permeability estimation in tight oil reservoirs using pressure decline versus time data
… shale is a difficult process because organic mudrocks have very low permeability (10nD - 100nD), high kerogen and clay content, a complex pore structure and low porosity (typically less than 10%). In addition, most of the pore sizes in organic mudrocks are within the nanometer range, thus making …

Impact of slickwater fracturing fluid compositions on the petrophysical properties of shale and tightsand
<p>"A tight reservoir always requires hydraulic fracturing before production to increase production rate. The additives in hydraulic fluids are highly considerable for a successful stimulation. A friction reducer is often used to reduce the flowing friction in the wellbore during hydraulic …

CO2 Minimum Miscibility Pressure and Recovery Mechanisms in Heterogeneous Low Permeability Reservoirs
… oil and gas resources, such as shale gas and tight oil, has grown quickly in 21th century and contributed to the North America oil and gas production. Although the new enhancing oil recover (EOR) technologies and strong demand spike the production of unconventional resources, there are still …

Development of a methodology for evaluating investments in infrastructure for the sustainable exploitation of shale energy in Argentina
… that were trapped in underground shale and tight rocks. In reality, these resources were known by geologists from the beginning of the oil industry, but only became economically extractable in the 2000s, with the use of two old technologies developed in the US and already used on …

Stress- and direction-dependent analysis of elastic and petrophysical properties, and texture in unconventional rocks
… the reservoir development of unconventional rocks. In this thesis, cores from multiple formations of the Bakken Petroleum System (BPS) were analyzed in the laboratory as examples of strongly and weakly anisotropic rocks. First, mineral compositions and total organic carbon of the rock samples …

LABORATORY-SCALE INVESTIGATION OF PERMEABILITY AND FLOW MODELING FOR HIGHLY STRESSED COALBED METHANE RESEROVIRS USING PULSE DECAY METHOD
… in the laboratory, is not applicable for tight rocks, higher rank coals and coals under highly stressed condition because of the difficulty in measuring steady-state gas flowrates resulting from the tight rock structure of. However, accurate estimation of permeability of highly stressed …
