Integrated Petrophysics For Reservoir Characterization Course
Introduction:
Rock Physics is a key component in oil and gas exploration, development, and production. It combines concepts and principles from geology, geophysics, petrophysics, applied mathematics, and other disciplines. Rock physics provides the empirical relationships, understanding and theory to connect petrophysical, geomechanical and seismic data to the intrinsic properties of rocks, such as mineralogy, porosity, pore shapes, pore fluids, pore pressures, stresses and overall architecture, such as laminations and fractures. Rock physics is needed to optimize all imaging and reservoir characterization solutions based on geophysical data, and to such data to build mechanical earth models for solving geomechanical problems. Attendees will obtain an understanding of the sensitivity of elastic waves in the earth to mineralogy, porosity, pore shapes, pore fluids, pore pressures, stresses, and the anisotropy of the rock fabric resulting from the depositional and stress history of the rock, and how to use this understanding in quantitative interpretation of seismic data and in the construction of mechanical earth models. A variety of applications and real data examples is presented. Faced with increased demands and growing competition, many utilities and industries are seeking to maximize the value of their existing assets by leveraging new technologies to optimize Operations and Maintenance activities. One of the most successful maintenance strategies is a conditioned-based approach which utilizes data collected from periodic inspections, testing and predictive maintenance technologies to determine the optimum maintenance requirements.
Course Objectives:
After attending this program, you will be able to:
- Introduce different competency measurement tools for a number of human resource development systems relating to organizational and individual growth in terms of competence standards, corporate transformation, implementation strategies, role models, and sustainable business performance.
- To get familiar with the relationship between competency on one side and self-development, human capital assessment, job-shift theory, and the design techniques of competency models on the other.
- To examine competency system usages, applications, documentation methodologies, ownership and practices contributing to the achievement of organizational business goals.
