This is the story of the drilling of a costly ($60 million) Lahee A-1 well in the Colombian foothills, which presented significant deviations from the prognosticated stratigraphy halfway to the objective – and became an operational nuisance. Nonetheless, it is mainly a story of successful management and prompt response to the geological uncertainty.

In last month’s Geophysical Corner `we described the different poststack impedance inversion methods that are available in our seismic industry. In poststack seismic inversion – where there is no mode conversion at normal incidence – it is purely acoustic. P-wave impedance is the only information that can be estimated from poststack inversion of P-wave data.

Seismic inversion for acoustic impedance is widely used in our industry today, mainly due to the ease and accuracy of interpretation of impedance data, but also because it allows an integrated approach to geological interpretation. This month’s column refers to “inversion” as the transformation of seismic amplitude data into acoustic impedance data.

The Anadarko Basin granite wash play has been considered difficult to interpret both geologically and geophysically. Consequently, the application of seismic attribute analysis to mid-continent washes has not been widely published.

BOEM’s regulatory role of G&G Permitting on the OCS provides an oversight mechanism which allows industry to collect G&G data (needed to explore and produce Outer Continental Shelf (OCS) mineral resources) in an orderly manner and ensures the data collection is done in an environmentally sound way to preserve and protect other OCS resources. The talk is focused on G&G permitting in the Atlantic. It lists (with illustrations) the various types of G&G permitted activities. In explaining the steps in the Atlantic permitting process, it highlights the coordination needed between BOEM and other agencies and typical mitigations that may be required related to marine mammals, protected species and archaeological resources.

Accurate interpretation of geophysical data, in particular reflection seismic data, is one of the most important elements of a successful oil and gas exploration program. Despite technological advances in data acquisition and processing and regular use of powerful computers and sophisticated software applications, you still face a tremendous challenge each time you begin to reconstruct the geologic story contained in a grid or volume of seismic data -- that is, to interpret the data. On occasion this interpretive tale can be clearly told, but most of the time each page of each chapter is slowly turned, and rarely is the full meaning of the story completely understood. Interpretation of Reflection Seismic Data from the Gulf of Mexico illustrates these concepts using real seismic data and actual exploration problems.
