Seismic Interpretation: An Integrated Process
|Date||Sept 7 - 8|
|Instructor||William Dean Powell|
|Discipline||Geophysics, Geology, Training Development|
This course also available in Beijing (18-19 Oct).
An interpretation of seismic data requires the application of a good understanding of geophysical basics, the competent handling of 2D and 3D picking techniques and familiarity with quantitative as well as qualitative interpretation tools. A better interpretation will result from the additional input of sound geological reasoning. But for the interpretation to have maximum validity, and ultimately provide the least risky route to discovering oil and gas, the seismic interpreter needs to know how to fully integrate the contributions from these and other sources, as well as how to overcome obstacles that interfere with the interpretation.Rather than concentrating on the mechanics of seismic picking, this course aims to help the participant develop an open and creative mindset to the prospect evaluation that needs to be the end-product of any interpretation. Such a mindset will value contributions from outside the strictly geophysical and embrace the geological risking process as a means of injecting rigour into the interpretation process itself. In two days, this course will help participants understand and integrate the range of considerations that will help validate a seismic interpretation and de-risk a drilling prospect
The course is designed primarily for geophysicists who have been in the industry long enough to have some familiarity with the use of seismic data in exploration, but have not had much experience in integrating the many elements that add credibility to an interpretation nor in actually generating drillable prospects. The material is presented in a way that would enable geoscience students and others involved in oil and gas exploration, such as geologists and managers, to gain a helpful familiarity with the role of seismic interpretation in deciding where to drill.
Dean Powell holds a Bachelor in Applied Science from the Queensland University of Technology. He began his geophysical career with a Chevron affiliate in Western Australia, gaining extensive experience in the acquisition, processing and interpretation of seismic data. Subsequently, he worked as a Perth-based geophysical consultant for many years providing project management as well as technical services on exploration and development projects in Vietnam, New Zealand and in many of Australia’s sedimentary basins.
Prior to resuming consultancy work in 2013, Dean was employed as a Principal Geophysicist with Origin Energy. In this capacity he supervised 2D and 3D seismic acquisition and processing projects; however his main responsibility was the interpretation and mapping of seismic data. Dean provided regional and prospect-scale mapping for exploration in many onshore and offshore regions in Western Australia and other parts of Australia, as well as in New Zealand, Indonesia, Malaysia and Vietnam.
Much of Dean’s experience has been in poorer data quality areas, enabling Dean to develop particular expertise in the interpretation of poor quality 2D and 3D seismic. Over the years, drilling on the basis of Dean’s prospect mapping has resulted in a number of commercially successful oil and gas discoveries.
Participants should have knowledge of basic seismic and geological concepts related to hydrocarbon exploration.
