The client wanted to delineate production zones within a gas reservoir in order to drill new wells. The project area was 400,000 Km2 . MT and Gravity measurements were made over 380 and 400 sites respectively. The PST network consisted of 80 stations operated for a period of 8 months.
By using as selection criteria the value ranges observed around a known productive horizon:
Vp : 5.1 to 5.3km/s || Vp/Vs : 1.78 to 1.80 || Density : 2.63 to 2.68g/cm3 || Log(rho) : 2.7 to 3.9 and Depths below 2km the following drilling sites were proposed
