Rock Physics - Integrating Petrophysical, Geomechanical, and Seismic Measurements
Average client rating (based on 117 attendee reviews)
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.

Bandung is the capital of West Java province in Indonesia. Located 768 m (2,520 ft) above sea level, Bandung has relatively year-around cooler temperature than most other Indonesian cities
Bandung is renowned for its large stock of Dutch colonial architecture; most notably the tropical Art Deco architectural style. The modern and native architectural blending was followed by several Dutch architects that have shaped the city landmarks. In the 1930s, Bandung was known also as the city of architecture laboratory because of many Dutch architects made some experiments with new architectural designs.
Bandung has served for popular weekend-break destination for people living in Jakarta for many reasons. The cooler climate of highland plantation area, the varieties of food, the cheaper fashion shops located in factory outlets and distros, golf courses, and the friendliness of local people have become the main attraction of the city.
Bandung Husein Sastranegara International Airport serves direct flights to Batam, Surabaya, Yogyakarta, Denpasar, Palembang and Padang and also international services from Kuala Lumpur and Singapore Changi Airport. The airport is located nearby the Dirgantara aerospace complex and Dirgantara Fairground.
