Title: Wellsite Geochemical Analysis in Frontier Exploration--Logistics, Benefits, and Examples: ABSTRACT

Author(s): Alun Whittaker, Rafael Gurvis

Article Type: Meeting abstract

Abstract:

In the past 10 years, organic geochemistry has become an increasingly significant factor in petroleum exploration. In frontier exploration areas, the need for geochemical data during drilling operations, rather than months after a well is finished, is now well appreciated. Real-time geochemical data have proven to be an important additional parameter in exploration and well completion decisions.

Wellsite geochemistry mandates unique operational, technical, and data interpretation requirements. However, the timely nature of data availability during drilling operations as well as the ability for field geochemists to work closely with other well-site personnel greatly enhances exploration efficiency. Sample procurement, preparation, and selection can be much more accurately realized by personnel familiar with local geology and a specific drilling operation. Furthermore, sample contamination by drilling fluid additives is more easily prevented, detected, and isolated from fresh samples at the wellsite.
