Due to the extensive and rapid processing of the Petrel program, we have relied on it to construct a three-dimensional geological model of the petrophysical properties of porosity, permeability, amount of saturation of hydrocarbons, GRV (Gross Rock Volume), N/G, Bo, In addition to determining the oil – water contact levels For the studied area (Sabban field, - Ruttba and Malussa Formations) in order to calculate the oil reserve in a specific way and compare it with previous studies in order to deepen the oil understanding of the region and identify potential drilling opportunities.
