Borehole Seismic Technology

Borehole Seismic data provides the critical depth and velocity parameters needed to link seismic data with downhole log and well data.

Borehole seismic tools have evolved from single-component sensors to modern seismic arrays. These moden tools, when combined with the latest technology in seismic source quality, navigational positioning, and computational abilities, can deliver in real time high-resolution borehole seismic images that extend beyond the wellbore or into the interwell volume to reduce risk in drilling and development decisions

This course provides a review of the latest tools, technologies, and applications of borehole seismic technology. A discussion of survery design and modeling is also included. This will provide an understanding of the applications of Borehole Seismic Data to Exploration, Reservoir Description, and Production.

    Bandung

    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 Sky Line

    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.
