Non-seismic methods as an insight to promote hydrocarbon exploration

Often systems are described in a play for a region and stated as a conceptual model for a specific hydrocarbon accumulation style and implemented in order to develop geological targets. The recognition of each systemelement involves the deployment of geological and geophysical studies and evaluation techniques to identify delineate and locate subsurface prospects. Each geological model is identified through its geophysical signature pattern. The latter becomes particularly important as exploration moves to detect smaller, more complex, and more remote targets. Although targets are getting smaller, exploration and appraisal wells can be sited more accurately allowing greater chance of success through the use of multi-source information. One of the successful tools of choice to assist with this endeavour has been the usage of Gravity data. This paper reports the results using gravity data for hydrocarbon exploration in central Tunisia. Gravity was used to define structural elements which constitute important aspects in the identification and definition of hydrocarbon plays.
