Identify Sand Channels within the Heterogeneous Units of Burgan Reservoir

Summary As a result of the previous mentioned study, the path of well (A) was planned to be drilled parallel to the fault simultaneously it was targeting the isolated sand channel. Post drilling well (A) found to be a very successful well where the oil found in all the four layers of Burgan reservoir including the massive sands. The sands in BGSU were well developed compared to the offset well, that’s matching with the theory we built from the inversion volume which suggested an isolated sand body exist in the area. The sands of BGSU unit were fully saturated with oil and no OWC was seen. Good net oil columns were encountered in the massive units (BGSM and BGSL2) where in the surroundings and in the remaining oil column maps these units are supposed to be drained. The presence of the sealing fault in the area was the main reason behind holding this oil from moving updip. This successful integration of data and findings clearly illustrate how by thinking outside the box and step out of our comfort zone helped us to reveal new opportunities and added more oil to KOC oil tanks
