... that are important when considering hydraulic fracturing for unconventional reservoirs. A processed log interpretation calibrated for the Haynesville Shale is computed using a typical triple-combo suite of logs. Other log data, such as borehole imaging, magnetic resonance, dipole sonic, and spectral gamma ray...

.... Hydraulic fracture stimulations to date at SR have encompassed limited entry "waterfrac" treatment techniques. The hydraulic fracture characteristics were interpreted to document possible influences that natural fractures, horizontal stress trends and sandstone channel orientations may have had on hydraulic...

... by conventional decline curves. This process can be applied to reserve evaluation as well as optimizing well spacing in the reservoir. The analysis is performed through interpretation of a diagnostic plot paired with an appropriate recovery plot (using well constraints and economics). It is validated using...

The program provides constrained cross-matching between rate, cumulative production, and time to obtain a unique and consistent interpretation regardless of the type of analysis. Main features of data input, cross-type-curve matching...

... and underestimation of gas reserves. Abstract Interpretation of pressure transient data using the derivative curve has proven to be an effective method for quantifying and qualifying well/reservoir information. Analyzing pressure response data affected by multiple rate changes is well understood and readily...

... stimulation are of paramount importance. Fracture model calibration, the other major facet of hydraulic fracture optimisation, is achieved by the interpretation of pre-fracture diagnostic injections. Improving the ‘uniqueness’ of these interpretations is thus another key area for enhancement. With a view...

.... The major problem in evaluating foamed cements is that their impedance values can be below that of annular fluids, such as mud or water. Thus, a standard interpretation of ultrasonic images and data in foamed cements may provide an incorrect diagnosis of the cement bond and could lead to unnecessary...
