Jens Danielsen and Stein Fanavoll from EMGS have, together with co-authors from Rocksource, published the scientific paper in The Leading Edge, an American journal owned by the SEG (Society of Exploration Geophysicists).
Reduces risk
The article evaluates results from wells drilled on prospects or fields covered by CSEM (Controlled Source Electromagnetic) data. The key finding is that the average success rate for exploration wells drilled on prospects with a significant CSEM anomaly is 70%, whereas it drops to 35% for wells drilled on prospects without a significant CSEM anomaly.
"This study clearly shows that CSEM technology can significantly reduce risk in the exploration process and improve exploration drilling success rates in CSEM suitable areas," says Jens Danielsen, EMGS's Vice President of G&G Solutions.
"The technology serves as an important risk reduction tool in a portfolio setting, where each prospect is analyzed as extensively as possible using an integrated approach where all available data are utilized."
Largest database to date
Of 86 wells with associated CSEM data, 50 are exploration wells drilled after the acquisition of CSEM data and 36 are calibration surveys (surveys acquired over an existing discovery or dry well to test the technology). This represents the largest database available to date.
