摘要： Downhole gravity measurements are used to monitor the volumetric sweep of CO2 and estimate the fingering phenomenon if any. The gravity measurements have been found to be effective due to the high density contrast between CO2 and brine or oil which provides better and higher sensitivity. An analytical forward model is used to determine the location and shape characteristics of the flooding front. A strategy to monitor the movement of the CO2 flooding front and to predict the fingering phenomenon is used to provide a warning tool to improve the sweep efficiency, according to some embodiments.

摘要： Systems and methods for analysis of drilling cuttings are described. Complex permittivity is measured of rock cutting samples obtained during drilling operations. The origin of the cuttings is known by flow rate analysis in the drilling system. Various means can be used for rock cutting dielectric measurement. For example, the dielectric measurement can be made by matching the unknown permittivity of the medium to be analyzed to the permittivity of known liquid mixtures by successive saturation and looking for a “zero-contrast” measurement.

摘要： Systems and methods are described for calculating pore pressure in a porous formation such as shale gas having substantially disconnected pore spaces. In some described examples, an NMR logging tool with at least two depths of investigation (DOIs) is used. The deeper DOI can be used to sample the shale gas that has not been perturbed by the drilling process, for example, and contains the gas at connate pressure. The shallow DOI can be used to sample shale gas that has been perturbed, and has lost at least part of its gas content. The micro cracks that have been formed in the shallow location (closer to the borehole) allow for injection of gas into the formation at known pressures while measuring the NMR response. The connate pore pressure can then be calculated for the deeper location based on the NMR response to the known pressure increase.

摘要： An open ended coaxial probe is disclosed that can be used to measure the dielectric properties of solids. According to some embodiments, the probe is specially designed to make good contact with solids having flat or non-flat surfaces. This design relies on forcing a good contact between the solid surface with both the center conductor and outer conductor of the coaxial probe. A method is also described in which the coaxial probe is used to monitor the dielectric permittivity of cylindrical samples such as rock cores drilled from a well. Also described are methods of using the coaxial probe to provide a continuous log of the dielectric permittivity of a rock core.
