Daleel Petroleum, a Muscat-based oil and gas exploration and production firm plans to harness the hydrocarbon potential of ultra-thin carbonate reservoirs to help boost the reserves potential of its Block 5 concession in Oman.

“Ultra-thin reservoirs, varying between one and three metres in thickness, are found scattered in some satellite fields around the Block, and not in all of the fields,” said Talal al Abdali, production geologist, was quoted as saying in an Oman Observer report.

“While conventional wells target thick reservoirs, we have succeeded in targeting these thin reservoirs through the use of lower cost logging tools. Initial production from some of the wells averaged 1,000 bpd, stabilising at 300 bpd. This is commendable overall given the low cost environment in which we are currently operating,” he added.

“Daleel Petroleum is proud to be one of very few oil companies to target ultra-thin reservoirs in the Sultanate,” said Talal. “We managed to drill a well for more than one kilometre laterally within a two-metre (target range), producing 1,000 bpd initially. This success gave us to confidence to launch a programme for the development of ultra-thin reservoirs. We also designed a special development programme for our young Omani geologists to improve their skills in geo-steering.”

“We managed to reduce the cost of drilling such wells by $200,000 per well. Several wells have now been designed and planned to be drilled in these thin reservoirs, which ultimately will add more reserves to Oman’s hydrocarbon potential.”

“We are also willing to share this expertise with other Omani operators as we are all working for the nation’s advancement,” he added.
