ISLAMABAD - Pakistan made two key oil and gas discoveries in the third quarter and another three discoveries in the fourth quarter of 2017. These discoveries may have prompted the US-based Exxon-Mobil to join offshore drilling efforts in Pakistan. American energy giant’s entry in Pakistan brings advanced deep sea drilling technology, its long experience in offshore exploration and production and its deep pockets to the country. US Energy Information Administration (EIA) estimates that Pakistan has technically recoverable deposits of 105 trillion cubic feet (TCF) of gas and 9.1 billion barrels of oil. Exxon-Mobil is expected to accelerate exploration and lead to more discoveries and increased domestic oil and gas production.
Top Countries Discovering Oil and Gas
Russia led with 10 discoveries, followed by Australia with seven discoveries and Colombia with four discoveries. Pakistan and the UK each had three discoveries in the fourth quarter of 2017, according to Global Oil and Gas Discoveries Review. (Oil and Gas Discoveries 2H/17. Source: Offshore Technology)
In fourth quarter of 2017, the Former Soviet Union leads with 12 discoveries, followed by Asia with eight discoveries, and Oceania with seven discoveries. Europe and South America had five discoveries each, followed by North America with two discoveries, while the Middle East and Africa had one discovery each in the quarter, according to Offshore Technology website.
Exxon-Mobil’s Entry in Pakistan
American energy giant Exxon-Mobil has joined the offshore oil and gas exploration efforts started by Oil and Gas Development Corporation (OGDC), Pakistan Petroleum Limited (PPL) and Italian energy giant ENI, according to media reports.
Each company will have 25 percent stake in the joint venture under an agreement signed at the Prime Minister’s Secretariat in May between ExxonMobil, Government Holdings Private Limited (GHPL), PPL, ENI and OGDC.
Pakistan Oil Basins
A Pakistan Basin Study conducted in 2009 found that the country has six onshore and two offshore basins; offshore basins being the Indus basin and the Makran basin in the Arabian Sea.
The Indus offshore basin is a rift basin that geologists say developed after the separation of the Indian Plate from Africa in the late Jurassic period. It is believed to be the second largest submarine fan system in the world after the Bay of Bengal with high probability of hydrocarbon discoveries.
The Makran Offshore basin is separated from the Indus offshore basin by Murray ridge, according to Syed Mustafa Amjad’s report in *Dawn*. It is an oceanic and continental crust subduction zone with deepwater trenches and volcanic activity. The basin consists of oceanic crust and periodic emergence of temporary mud islands along the coast suggesting strong evidence of large hydrocarbon deposits.
Pakistan Hydrocarbon Potential
The United States Energy Information Administration (EIA) estimates that Pakistan has 586 TCF (trillion cubic feet) of gas in Pakistan of which 105 TCF is technically recoverable.
In addition to gas deposits, US EIA estimates there are 227 billion barrels of oil in Pakistan with 9.1 billion barrels being technically recoverable.
Pakistan also has 185 billion tons of coal deposits in Thar desert which are just beginning to be extracted by Sindh Engro Coal Mining Corporation.
Oil and Gas exploration and production companies are currently planning to drill 90 wells in different parts of the country. Under the plan, as many as 50 exploratory and 40 development wells would be drilled in a bid to make the country self-sufficient in the energy sector, according to media reports.
During the last five years, the sources said the exploration and production companies drilled 445 new wells, out of which 221 were exploratory, adding that the increased exploration activities resulted in 116 new oil and gas discoveries.
