Operated Fields
Ratana Field
Ratana field is located approximately 100 kms. Southwest of Islamabad in northern Punjab Province in oil producing Potwar region. Discovery was made in 1992 whilst production started in July 1993. The working interest owners in D&P Lease are Orient Petroleum (Operator) 65.91%, OGDCL 25%, POL 4.545% & AOC 4.545%. Chorgali/Sakesar, Patala, Lockhart, Datta & Wargal are the five proven reservoirs with over 2500 feet of hydrocarbon column. Five wells with various sidetracks have been drilled on Ratana structure.
The new well Ratana-5A will be drilled as a replacement well of Ratana-5 in the year 2024 based on the MEM study. The drilling objectives of Ratana-5A are enhancement and sustainable production from Ratana Field.
The production facilities are installed at Ratana-2 location which includes 20 MMSCFD capacity amine sweetening plant, 30 MMSCFD capacity dehydration unit, two HP separators, condensate storage tanks and loading bay etc. The produced gas is processed at OPI Facility.
Dhurnal Field
Dhurnal oilfield located 60 Kms. southwest of Islamabad in the Potwar Plateau, Upper Indus Basin. It was discovered in 1984. The working interest owners in D&PL are Orient Petroleum (operator) 70%, OGDCL 20%, POL 5% and AOC 5%. Seven wells have been drilled on Dhurnal structure, out of which four are producers while the remaining three are water injectors. To ensure stabilized production, efficient water disposal & maximize recovery, an environmentally friendly water injection recovery project was implemented in 1987. This was the first ever secondary recovery project in Pakistan. Dhurnal was the largest oil producing field in Pakistan with peak production of 20,162 BOPD in 1988.
Field production facilities consist of 30 MMSCFD capacity gas dehydration unit, HP separators, LP separators with de-salters, coolers/heat exchangers and storage tanks. One HP gas compressor powered by gas driven engines is used for gas lift purposes.
Bhangali Field
Bhangali field is located about 60 kms. South of Islamabad in the Potwar Plateau of the Upper Indus Basin. The field was discovered & started regular oil/gas production in 1989 after successful drilling/completion of Bhangali-1 in the naturally fractured carbonate Chorgali/Sakesar reservoirs. The current working interest owners in D&P Lease are Orient Petroleum (operator) 90%, POL 7% & AOC 3%.
The Production facilities consist of one HP separator, Coolers/heat exchangers and plant storage tanks.
Zamzama Field
Zamzama gas field lies 10 Kms. west of Dadu City in the province of Sindh, Pakistan. The field was discovered in 1998 & brought on-stream in 2001. Working interest owners in D&PL are Orient Petroleum Inc. (operator) with 38.5%, GHPL with 25%, Eni with 17.75%, Alhaj (AEPL) with 9.375% and KUFPEC with 9.375%.
At present, 13 wells have been drilled on the field and state-of-the-art surface facilities with over 500 MMSCFD in capacity have been installed. A peak production of ~600 MMSCFD gas was recorded in 2009. Based on data from recent studies, Orient Petroleum Inc. is planning to drill more wells to exploit deeper potential in Lower Goru & Chiltan formations.
