Geomechanical Project Management
ARG applies technical excellence to deliver fully integrated, multidisciplinary solutions to the most challenging geomechanical problems from data acquisition and development stage to design and operation stages. This encompasses the full cycle of geomechanical services, from scoping of the work, selection of contractors for various components of field, lab, and modeling tasks, supervision of activities on site, integration, interpretation, and reporting of the findings.
Both conventional and unconventional recovery process could significantly benefit from a high-quality geomechanical monitoring system. The data collected through field surveillance could help develop a better understanding of reservoir performance, improve the accuracy of numerical simulations, and to provide information that could be used to prevent caprock failure or casing collapse. ARG provides consultation, design, and interpretation for a wide range of geomechanical monitoring techniques such as multi-satellite multi-track surface heave/ subsidence monitoring, surface and down-hole tiltmeters, extensometers, radioactive markers, micro-seismic / passive seismic system, as well as pore pressure and temperature monitoring for caprock integrity.
To ensure that the most representative and accurate geomechanical parameters are measured we provide consulting, design and management for the full cycle of geomechanical characterization. This includes planning and supervision of well site services such as core recovery and preservation, as well as quality control of recovered cores and obtaining necessary samples. We design a laboratory program consisting of continuous strength measurement, comprehensive index tests, advanced rock mechanics and rock physics tests, and tight rock analysis for the reservoir and caprock.
In order to create a representative geomechanical model, all available data including geological evaluation, geophysical interpretation, petrophysical analysis including dynamic elastic parameters and FMI logs, laboratory tests, and field measurements of in situ stress and pore pressure need to be compiled and integrated. ARG provides an optimal scope of work and choice of best acquisition and investigation plans as well as selection of required sub-contractors and final integrated report identifying the benefits of each geoscience element.
State-of-the-Art Numerical Modeling
ARG provides expert computational geomechanics solutions by bringing the most advanced numerical platforms into play. This includes 3D finite element and finite difference solutions with advanced constitutive models, fully coupled analysis of multiphysics systems with arbitrary set of physics, Distinct Element analysis of rock mass including natural fractures and faults, reservoir simulation coupled with modern geomechanical softwares, hydraulic fracture simulation, and Discrete Fracture Network modelling. We are confident that this approach provides the most robust, fast, and affordable solution to our clients.
In Situ Stress Analysis
Principal in situ stresses are one of the most important input parameters to geomechanical models. Our aim is to ensure that the most effective stress measurement and interpretation techniques are applied for an optimal number of intervals to achieve a high precision results at minimum cost. We provide recommendations, planning, and supervision of field experiments. Also, we evaluate, analyze, and compile an interpretation
report and recommend new methods and technologies for characterization of in situ principal in situ stresses. This would include an integrated study of the drilling and multi-arm caliper logs as well as tectonic strain analysis. Analysis of pressure decline data before and after closure provides additional valuable data such as formation pore pressure and permeability.
