The multistage hydraulic fracturing is the best practice to stimulate unconventional hydrocarbon reservoirs for optimal production in oil & gas industry. Recent studies suggested that the selective stimulation design could significantly increase the production rates at a reduced cost rather than using the non-selective geometric stages. An optimal design needs a detailed geomechanical logging and core information to selectively perforate the formation and optimize the stimulation treatment. In most cases, the non-selective evenly spaced geometric stimulation design is used, primarily due to the time consuming and expensive conventional downhole logging tools and techniques. Rocsol’s D-Series is a convenient, cost-effective technology that uses a 3D wellbore friction model to estimate the effective downhole weight on bit (DWOB) from routinely acquired surface weight on bit, hookload, RPM along with the survey data and drill string information in directional drilling. The estimated DWOB is used as an input to the inverted rate of penetration (ROP) model along with other drilling data, drill bit specifications and reservoir specific formation constants, to calculate rock mechanical and reservoir properties including, the compressive strengths, Young’s modulus, porosity, permeability and Poisson’s ratio without the use of expensive downhole logging tools.

In unconventional reservoir this technology can be used to engineer stimulation design by selecting sweet spots from the recognized behaviour of geomechanical properties. Unlike the current practice using logs of 1 in 10 or 1 in 20 well, a complete geomechanical log can be obtained on every well. This novel technology could help geologists and reservoir engineers better exploit unconventional reservoirs leading to optimal selective stimulations and greatest net present value (NPV).

In this session the speaker will deliver a brief demo on the D-Series technology to calculate the geomechanical properties using a set of sample field data from a horizontal drilling in North America.
