... to estimate reservoir pressure for each stage from the fall-off data analysis. A new method has been developed to estimate the final frac stage pressure gradient after the frac is complete. This method is based on using pumping and leak-off data to calculate each stage pressure which will be used to match...

... in Montney horizontal wells using gas and cuttings composition as well as reservoir pressures. New approaches have been defined for three types of data. Gas chromatography (C1-C6+) has been analyzed looking at the coherency of the various gas molecules against each other. Anomalous cuttings composition...

...), they tend to arrange themselves as similar stages. The best-fit line that connects them is defined as the transfer function. The slope of the transfer function describes the rate of change of ISIP with respect to the initial ISIP. The magnitude of the slope is dominated by surface area, reservoir pressure...

...-saturation fluids. Our mapping reveals an extensive over-pressured light oil play in northeastern British Columbia that is still largely under-explored. Our approach can help understand the distribution and geological controls of in-situ fluids and reservoir pressure, to better predict risks associated...

... by the interplay between the competing opposite effects of drawdown, compressibility and relative permeability. Transient IPRs are not based on average reservoir pressure, but on specified times. In fact, we propose a triple combo IPR consisting of a set of 3 flow durations (e.g. 30-, 90- and 180-days, or 1-, 3...

... Abstract A new Diagnostic Fracture Injection Test (DFIT) procedure and analysis method was recently introduced whereby flowback data, obtained immediately after pump shut down, is analyzed for closure pressure ( p c ), reservoir pressure ( p r ) and reservoir productivity (well productivity...

In the second case, fracture propagation analysis of water injection wells was performed with potential completion problems (i.e. tubing...
