Abstract

Controlled Source Electro-Magnetic (CSEM) surveys have proved to be useful in de-risking the hydrocarbon prospects in the deep water environment, due to their capability to distinguish between the brine and hydrocarbon saturated reservoirs. However, the interpretation of CSEM response in marginal water depths and complex geological setups remains challenging due to the interference of airwave with electromagnetic field and the background resistivity variations. In the year 2006, PETRONAS conducted a pilot CSEM survey in one of its offshore block in Southeast Asia. The survey was aimed to understand the key risks of the two hydrocarbon prospects identified in the area and to evaluate the strengths and limitations of the CSEM technique for its future application in shallow water depths and complex geological setups.
