Oilsuch

Oilsuch is a term used in some German-language sources to describe the activity of searching for crude oil deposits. It encompasses the exploration process from regional geological assessment to the application of geophysical and geochemical methods, and the evaluation of prospective reservoirs, plays, and traps. In practice, oilsuch combines geological mapping, analysis of source rocks and maturation, and the use of seismic surveys to image subsurface structures and stratigraphy.

During the exploration phase, prospects are ranked according to geological risk, potential volume, and economic viability. Geophysical methods such as 2D and 3D seismic imaging, gravity and magnetic surveys, and surface geochemical techniques help identify likely hydrocarbon traps. If results are favorable, appraisal activities follow, including additional drilling, well testing, and reservoir characterization to determine deliverability and reserve estimates.

Modern oilsuch relies on technological advances such as high-resolution 3D seismic, real-time drilling data, and integrated data interpretation. Economic considerations, including oil prices, capital expenditure, operating costs, and regulatory requirements, influence the level of activity and site selection. Environmental and social governance factors, permits, and environmental impact assessments also shape exploration plans.

While the term is more common in German-speaking contexts, in English-language industry literature the activity is typically referred to as oil exploration or oil prospecting, and the underlying practices align with petroleum geology and exploration geology.
