Abstract: Fluids are pumped into a wellbore (106) by pulsing the fluids at a variable, positive pressure relative to the geologic formation until a first pressure threshold in the first fracture zone is satisfied. The pumping results in a first pressure profile in the first fracture zone representing pressures in the first fracture zone over time responsive to the pumping, and a second pressure profile in the second zone representing pressures in the second zone over time responsive to the pumping. In response to determining that the first pressure threshold is satisfied, the fluids are ceased to pump into the wellbore for a duration of time. After the duration of time, the fluids are re-pumped into the wellbore by pulsing the fluids at the variable, positive pressure relative to the geologic formation until a second pressure threshold in the first fracture zone in the first fracture zone is satisfied.

Abstract: A measure of inter-reservoir cross flow rate between adjacent reservoir layers which are productive of hydrocarbons is determined. With passage of time, pressure differentials between reservoir layers can grow due to continuous production from an active layer. In addition, the flow area between an active layer and adjacent layers can grow with time for a given reservoir system. These changing pressure and flow conditions with time can contribute to substantial amounts of cross flow rates, which need to be accounted for when characterizing the commercial producibility of the active layer. The inter-reservoir cross flow rate is based on a measure of specific permeability and of cross flow rate within a reservoir layer which is obtained from pressure transient tests of the reservoir formations.

Abstract: A hydraulic fracture diagnostic system for reservoir evaluation of a high angle wellbore includes coiled tubing that extends from the surface to a wellbore location. The system includes a sensor and a pump connected to the coiled tubing and a pump and sensor connected to an annulus between the coiled tubing and the wellbore casing. A tool having at least two packing elements and a port positioned between the packing elements is connected to the coiled tubing and is positioned adjacent a fracture. The packing elements isolate the fracture and the port is configured to provide communication with the isolated portion of the wellbore. A diagnostic method includes pumping a volume of fluid into the isolated portion of a wellbore and monitoring the pressure within the annulus via the coiled tubing. The tool may also be used in an openhole portion of a wellbore to diagnose the formation.

Abstract: A method is described for the recovery of hydrocarbon from a reservoir. The method comprises arranging a chamber in fluid communication with the reservoir via at least one conduit, and having the chamber comprising first and second wall parts movable relative to each other. An impact pressure is provided in the fluid to propagate to the reservoir via the conduit, where the impact pressure is generated by a collision process between an object arranged outside of the fluid and the first wall parts for the first wall part to impact on the fluid in the chamber. Further, the chamber is arranged to avoid a build-up of gas-inclusions where the first wall part impacts on the fluid. This may be obtained by arranging the conduit in or adjacent to the zone where the gas-inclusions naturally gather by influence of the gravitational forces, or by placing the first wall part impacting on the fluid away from this zone. The invention further relates to a system for the generation of impact pressure as mentioned above.

Abstract: Permeability prediction systems and methods using quadratic discriminant analysis are presented. At least one disclosed method embodiment includes: acquiring formation property measurements at a plurality of positions along at least one borehole in a study area; identifying clusters in a plurality of points representing the formation property measurements at the plurality of postions; and determining a system permeability value for each cluster.

Abstract: System and/or methods for removing noise from measurement data are disclosed. For example, pressure measurements may be used to identify a flow regime using the derivative of each of the pressure measurements. A time window may be defined about each pressure measurement and numerous or even all pressure measurements within the time window may be used to calculate the pressure derivative of each pressure measurement. A least-squares method or a least-absolute-deviations method may be used to compute a pressure-derivative curve. The iteratively-reweighted least-squares method may be used to solve least-absolute-deviation problems to compute a pressure-derivative curve with enhanced smoothing.
