The field of this study is located offshore Abu Dhabi (UAE). The primary target reservoir is the Pre-Khuff Fm., a deep tight gas sandstone that can be found at depths exciding 16,000 ft with temperatures above 350º F. The objective of this presentation is to describe the analysis, design and implementation of hydraulic fracturing technologies that improved the well performance by more than 800% in the first successful hydraulic fracture treatment pumped offshore Abu Dhabi.

Introduces geoscientists and engineers to the discipline of petroleum geomechanics. It will be demonstrated that geomechanics adds value in all phases of exploration, development and production. Provides a conceptual framework for petroleum geomechanics which emphasizes fundamental concepts, properties, Earth stresses and data inputs that contribute to Mechanical Earth Models (MEM).

Upon completing this Learning Module assignment, the participant should be able to apply rock mechanics fundamentals to describe well, reservoir and production behavior and define the following rock mechanical properties under various conditions of confining pressure, describe how these properties influence wellbore stability, directional drilling considerations, well completion design and other aspects of reservoir development, and know how they are measured in the laboratory: Brinell hardness, tensile strength, normal/shear stress relationships and failure mechanisms (Mohr circles), Young's modulus, Poisson's ratio, compressive strength, and shear strength.

In this SPE Tech Talk with SLB, we discuss the InSitu Geomechanical Profiling workflow for oil & gas, CCS projects, and more. Join these experts as they dive deep into the key to mitigating risks across various applications, from well construction to production and even CO2 injection and storage.

Reducing the amount of CO2 in our atmosphere is a critical goal that we all recognize as essential. Addressing the issue requires careful consideration of different reservoirs that can be utilized for sequestration purposes, including coal seams, enhanced oil recovery, depleted hydrocarbon reservoirs, and deep saline aquifers. Currently, there is a growing interest in deep saline aquifers due to their vast storage potential and the absence of previous penetrations that may lead to CO2 leakage. Nevertheless, the long-term consequences of CO2 injection on the seal and reservoir rocks remain uncertain, specifically with respect to water pH levels. Research suggests that significant CO2 equilibration with lowsalinity waters could result in the pH of brine reaching 3.5 pH, exhibiting a deleterious effect on calcite, potassium feldspars and high surface area clay minerals. Furthermore, multiple minerals could be adversely impacted by prolonged exposure to CO2. Fortunately, software packages such as PHREEQC and OLI permit static and dynamic geochemical models, while established core analysis methods can assess variations in strength, texture, and visual appearance of both seal and injection reservoir rocks. As such, we will delve into these conventional core analysis methods to evaluate potential changes in rocks with very low permeability and porosity, as well as high-quality target injection reservoirs.

Achieving global net-zero emissions goals will be impossible without CCUS. To be successful, CCUS project teams must meet time and cost constraints while addressing three major engineering stages: 1) CO2 Capture, 2) Transportation 3) Geological Storage. In this webinar, we will focus on Geological Storage modeling & simulation capabilities. In general, Geological formations for CO2 storage must have sufficient capacity and injectivity as well as the ability to confine the lateral or vertical migration of CO2 to the surface. By attending this webinar, you will learn how multiphysics and multiscale simulation, including geomechanics simulation with SIMULIA Abaqus and pore-scale simulation with SIMULIA DigitalROCK, a virtual rock lab, are used to avoid costly mistakes and project delays by assessing CO2 storage capacity, injectivity and containment.

In this webinar, the speaker presents a next generation vision for a state-of-the-art dashboard (QDashRT) driven by machine learning that provides drillers and operations geoscientists with real-time guidance for several mission-critical parameters and measurements. These include a sub-seismic resolution earth model, parameterized with pore pressure and geomechanical properties that are updated in real-time with new LWD data and enables ahead-of-the-bit and away-from-the bit visual awareness of potential drilling hazards; also included is a drilling parameter advisory system driven by an ROP simulator that considers transitions in rock properties; a synthetic logging and seismic-to-well tie product that, in the first instance, simulates DTC, DTS and RHOB for use in real-time pore pressure and geomechanical analysis, and in the second instance, facilitates the most accurate location of the well relative to geologic structure available in real-time. Finally, a novel implementation of a recurrent neural network is used to detect, in advance, the onset of a potentially hazardous formation, such as highly fractured carbonates or depleted sands. The individual components of the workflow will be described, along with the underlying data science framework and the Midland Basin geology targeted by the real-time earth model.

Geomechanics is a critical component for the development of deep geothermal resources. This talk will highlight the difference between hydro-thermal and petrothermal systems in terms of characteristics, required technologies, risks and costs and then review some geomechanical aspects related to drilling, and hydraulic stimulation of these reservoirs.

The next several decades pose enormous challenges, and opportunities, for the global oil and gas industry. While oil and gas will continue to be used for decades to come, it is now recognized that enormous quantities of CO2 have to be stored in subsurface geologic formations to reach global decarbonization goals. In this talk, the presenter will focus on a number of geomechanical issues that have to be considered to ensure long-term storage efficacy.

Faults at many scales impact fluid flow in producing hydrocarbon fields, and focus deformation due to fluid pressure changes, potentially causing overburden leakage and induced seismicity in the reservoir, overburden, or underlying basement. This seminar firstly reviews how the petrophysical and mechanical properties of fault zones control their response to reservoir pressure changes during production (depletion, injection), and consequently their geomechanical behaviour in terms of fault stability.
