    Abstract: A method of fracking carbonate-rich reservoirs, comprising injecting a cryogenic or chilled fluid followed by an acid into the reservoir, allowing the acid to etch the reservoir, and thereby increasing production of a fluid, such as water, oil or gas, from the reservoir. Further, injecting a preflush into the reservoir and later injecting a postflush into the reservoir to displace the acid from the tubulars into the reservoir.

    Abstract: Methods of analyzing and optimizing a seismic survey design are described. Specifically, the sampling quality is analyzed as opposed to the overall quality of the whole survey. This allows for analysis of the impact of the offsets, obstacles, and other aspects of the survey on the sampling quality, which will improve the ability to compress the resulting data and minimize acquisition footprints.

    Abstract: This disclosure describes a novel method for predicting continuous wellbore mechanical properties such as static elastic stiffness and failure strength, where the properties solutions are deterministic and based on mechanical theory. It has at least three immediate applications: (a) continuous plots of mechanical properties vs. depth, (b) conceptual testing of the effect of changing constituent volume fractions, (c) ternary plots.

    Abstract: Offshore system for delivering geotechnical tools to seafloor is described. The system includes a carrier tube that includes an upper end and a lower end, wherein the carrier tube is characterized by an outer diameter and an inner diameter and wherein the inner diameter of the carrier tube defines a hydraulic cylinder; a landing sub shaped or installed at or near the upper end of the carrier tube, wherein inner diameter of the landing sub is smaller than the inner diameter of the carrier tube; a drill bit shaped or installed at or near the lower end of the carrier tube; an extension tube extending upward from the upper end of the carrier tube; an upward seal that seals top portion of the extension tubes; a compression system for introducing compressed fluid under the upward seal; a fixed rod that runs through the hydraulic cylinder; a hydraulic piston disposed in the hydraulic cylinder, wherein the hydraulic piston is moveable along the fixed rod; one or more shear pins configured to restrict displacement of the hydraulic piston until a sufficient fluid pressure is built up; and an inner tube disposed between the carrier tube and the hydraulic piston, wherein lower portion of the inner tube includes a cone penetrometer that is ballistically inserted into the soil during downward displacement of the hydraulic piston.

    Abstract: The present disclosure describes a method that improves the long-range geobody continuity in Multiple Point Statistical methods, wherein the coarsest multi-grid level cells are simulated in a regular path, and the subsequent level cells are simulated in a random path as usual. The method is general and is applicable to different cases: such as hard data conditioning, soft data conditioning, non-stationarity modeling, 2 or more than 2 types of facies modeling, and 2D and 3D modeling. The method is particularly useful in reservoir modeling, especially for the channelized systems, but can be generally applied to other geological environments.
