Abstract: A method for calibrating fracture networks. The method includes estimating an average fracture width of a fracture network using one or more of net fracturing pressure, Poisson's ratio, shear modulus, and fracture height; determining microseismic event envelope and base intensity data using a three-dimensional geomodel including microseismic event data; and determining hydraulic fracturing treatment (HFT) fracture intensity of post-hydraulic fracturing treatment (post-HFT) based on the average fracture width and HFT volume data. The method further includes calibrating the base intensity data to the HFT fracture intensity to obtain calibrated HFT fracture intensity, determining a proppant transportation and distribution scenario, and generating a dual porosity reservoir model based on the calibrated HFT fracture intensity and the proppant transportation and distribution scenario.

Abstract: Methods for estimating an unknown value for a dynamic under-balance condition are herein disclosed. The unknown value may be a well property value, or may be a transient pressure characteristic. Embodiments of the method include selecting at least one transient pressure characteristic and selecting at least one well property value. A correlation between the at least one transient pressure characteristic and at least one well property value is obtained. The unknown value is estimated by applying at least one known transient pressure characteristic or at least one known well property value to the obtained correlation.

Abstract: A perforating system having a perforating gun with a tubular gun housing defining an inner volume and extending in an axial direction. A shaped charge is held in a loading tube. The loading tube is located in the gun housing. The loading tube extends along the axial direction. The shaped charge faces in a firing direction substantially perpendicular to the axial direction. A portion of the gun housing adjacent to the shaped charge in the firing direction is a perforating portion for removal upon firing of the shaped charge. An eccentralizer member extends from the perforating gun in a second direction that is substantially opposite and parallel with the firing direction. A first retainer part extends from an outer surface of the gun housing adjacent to the perforating portion. A second retainer part extends from the outside of the gun housing adjacent to the perforating portion.

Abstract: The invention relates to fluid sampling in a test that is used to determine physical and chemical characteristics of the fluids in a subterranean reservoir. The method reconstructs the entire pressure history of the fluid parcel that is captured in the fluid samplers during a test. Using this reconstructed pressure history of the samples, the quality of the samples, particularly, whether there is a phase change in the samples during the test, can be accurately quantified.

Abstract: A technique is provided for optimizing well production. Intervals are selected along a deviated wellbore, and a well test and treatment string is deployed in the wellbore. Each interval is then isolated to enable performance of desired testing. The test data obtained is evaluated to determine an appropriate remedial action which is then implemented via the well test and treatment string. The system and method enable the testing and treatment of a plurality of intervals along a horizontal well during the same run downhole.
