Abstract: Techniques for calculating metrics for reservoir quality based on light oil and total organic carbon in tight oil reservoirs are described. The techniques include calculating quantities of light oil and total organic carbon from logging data and generating therefrom a continuous log for reservoir quality metric. Additionally new reservoir quality indices are presented that more accurately predict reservoir quality in tight oil plays.

Abstract: A method for identifying low resistivity low contrast high temperature high pressure productive subsurface formations rich in acid gases penetrated by a wellbore includes obtaining dielectric permittivity measurements of selected formations adjacent at least part of the wellbore. Nuclear magnetic resonance relaxometry measurements are obtained for the selected formations, the relaxometry measurements being calibrated to identify relaxation times corresponding to acid gases in high humidity at elevated pressure and temperature. Zones are identified for withdrawing formation fluid samples based on the dielectric permittivity and relaxometry measurements.

Abstract: A tool having a pump-out unit, pumping unit, and NMR unit is disposed in a wellbore. On a pump-up cycle, after removing borehole fluids, a fluid is injected into a region of investigation. NMR measurements are made while fluid migrates into the region of investigation. On a production cycle, pressure is removed, allowing fluid to exit the formation while NMR measurements are made. A rate of fluid production is estimated using the time-dependent NMR measurements. Alternatively, the mass of a sample is measured. Fluid is injected into the sample and the mass of the injected sample is measured. Pressure is removed and the mass of the injected sample as the fluid migrates out of the sample is measured. The change in mass of the injected sample as the fluid migrates out of the sample is determined and a rate of fluid production is estimated using the determined change in mass.

Abstract: Treatment methods and treatment fluids for increasing permeability of organic shale formations are described herein. The treatment method includes treating an organic shale formation with a treatment fluid. The treatment fluid includes a solvent that dissolves bitumen in the shale formation. After treating the shale formation with the treatment fluid, oil is recovered from the shale formation. By removing bitumen from pores and pore throats within the formation, the solvent increases permeability of the formation and allows mobile oil to flow more easily through the formation.

Abstract: A method to detect presence of hydrocarbons in a subterranean formation. The method includes identifying a geological interval in the subterranean formation, analyzing a measurement of a rock sample obtained from the geological interval to generate a rock sample analysis result, wherein the rock sample analysis result indicates the presence of hydrocarbons in the geologic interval, analyzing, in response to the rock sample analysis result indicating the presence of hydrocarbons, a supplemental measurement different than the measurement of the rock sample to generate a supplemental analysis result, wherein the supplemental analysis result further indicates the presence of hydrocarbons in the geologic interval, performing, in response to the supplemental analysis result further indicating the presence of hydrocarbons, a logging operation to obtain azimuthal resistivity data of the geological interval, and presenting the rock sample analysis result, the supplemental analysis result, and the azimuthal resistivity data to a user.
