DHURNAL :

The Dhurnal Oilfield was discovered in 1984 and was acclaimed to be the largest oil field in Pakistan. It is located 60 kms south west of Islamabad, in the Attock District in North Potwar region. OPII, carrying majority working interest, is successfully operating under the Dhurnal Mining Lease along with Joint Venture Partners: Oil and Gas Development Company Limited, Pakistan Oilfields Limited and Attock Oil Company since 1982. In order to ensure enhanced and stabilized production and efficient water disposal, an environment friendly water injection secondary recovery project was implemented at Dhurnal, which was the first ever-secondary recovery project in Pakistan. To date production from the field has been 50 million barrels of Oil, 129,000 MMscf of Gas and 393,000 metric tons of LPG. Joint Venture Partners lead by OPII as Operator are at advanced stage of initiating a tertiary recovery project to enhance production by introducing new technologies of an international level. OPII has 70% Working Interest in the field.

BHANGALI :

Discovered in 1989, the Bhangali Oilfield in the Soan Block is located in Gujar Khan, Rawalpindi in the prolific Potwar Oil Basin. Oil production started in October 1989 whereas the sales started in August 1990. It is being operated under the joint venture partnership of OPII, Oil and Gas Development Company Limited, Pakistan Oilfields Limited and Attock Oil Company since 1988. To date production from the field has been 3.7 million barrels of Oil, 9,000 MMscf of Gas and 1,600 metric tons of LPG. OPII has 40% Working Interest in the field.

RATANA :

Since 1991 OPII, Oil and Gas Development Company Limited, Pakistan Oilfields Limited and Attock Oil Company have been working at Ratana Oilfield located at Pindigheb/Jand, Attock. Discovery was made in the Ratana Concession in 1992 whilst production started in July 1993. The Ratana field contains a horizontal well, which is believed to be the world's deepest horizontal completion. In 2002, OPII discovered gas and condensate in a previously unexplored zone by undertaking a work over program in an existing well (Ratana-II). Gas production is being sold to Sui Northern Gas Pipelines Limited after extraction of Sulphur and LPG at Pakistan Oilfields Meyal facilities. Despite marginal production, the dedication and commitment of Orient's team has not left any stone unturned to tap the full resource potential of the previously bypassed Eocene Zone and resulted in the discovery of new production possibilities. First quarter of 2007 is marked as another remarkable achievement of OPII’s expertise with Oil and gas discovery in Ratana Deep # 1 from Datta Formation of Jurassic age by deepening Ratana # 3 to Kingriali Formation of Triassic age. To date production has been 1.4 million barrels of Condensate, 32,600 MMscf of Gas and 4,900 metric tons of LPG. OPII has 65.91% Working Interest in the field.

MIRPUR KHAS BLOCK :

The Mirpur Khas Block is located in Hyderabad and was granted to OPII in December 1999. OPII has drilled fifteen exploratory wells in this concession on behalf of Joint Venture Partners, Bow Energy Resources, Government Holdings Private Limited and Zaver Petroleum Corporation Limited. OPII's consistent efforts and expertise have led to significant discoveries of Kausar Deep-1 in August 2003 and Usman-1 of gas during initial production testing. To add to the impressive run of exploration operations in the area Umar-1, Ali-1 and Ahmed-1 were discovered. The gas/condensate and oil production from this Block was commercialized on a fast track basis by laying the necessary pipelines and installing a gas purification plant, which is processing raw gas to pipelines specifications for onward sale to Sui Southern Gas Company Limited. In July 2006, a Gas Sales and Purchase Agreement was signed with Sui Southern Gas Company Limited (SSGCL) for the gas supply for a period of fifteen years.

With one of the largest drilling programs in place at Khipro, OPII has drilled fourteen exploratory wells out of which five significant gas/condensate discoveries and one oil and gas discovery have been made. These include Naimat Basal, Siraj South, Bilal North, Bilal-1, Kamal North and Rahim. These discoveries are expected to save considerable fuel imports to the country. In addition OPII has installed a gas purification plant, which is processing raw gas to supply to Sui Southern Gas Company Limited. An LPG extraction plant has been installed at the Naimat Basal Facilities.
