PETROLEUM HISTORY
PETROLEUM & GAS EXPLORATION
Petroleum History Oil used since ancient times, both for
lighting and medicine and by the Greeks even for warfare.
In 1859 at Oil Creek near Titusville in West Pennsylvania an oil well was drilled about 25 m deep which produced 8-10 bbl./days
PETROLEUM HISTORY in PAKISTAN Onshore
First exploratory well drilled by the Punjab Government near an oil seapage at Kundal (khisor Range, KPK in 1866, just seven years after the world’s pioneer well in Pennsylvania (USA) drilled by Col. Drake.
Similarly in 1885 – 1892, thirteen wells were drilled near Khattan oil seepage (south east of Quetta) produced about 25000 bbl of oil.
Rules and Regulations
First government PPR was issued in 1949. Thereafter BOC & AOC established PPL & POL In 1952 first maiden discovery on the Sui
Structure (Indus Basin) was done by PPL in Sui Main Limestone of Early Eocene age. Gas reserves estimated were 8.6 TCF= 1 Billion bbl of oil.
Rules and Regulations Petroleum Concession Agreements in 1954-
59 with following contries Standard-Vacum Oil company Hunt International Oil Company Shell Oil Company Sun oil Company Tide Water( All from USA)
Further Exploration During 1956-59, thirty five exploratory wells
were drilled and this could be described as a period of extensive exploration in Pakistan.
In 1960’s Shard decline was noticed. Why? In 1965 OGDC first successful discovery was
made (Sari Singh, Sindh followed by TOOT (Potowar, Punjab), Rodho ( Punjab 1972), Kothar ( Sindh, 1973), Dodhak (Punjab, 1977)….
Further Exploration First Natural Gas discovery in Punjab was
done by OGDC ( Nandpur 1984) ( Punjpir 1985) in Jurassic/ Cretaceous reservoirs.
LASMO made a gas discovery in Lower Goru Sandstone ( Cretaceous) at Kadanwari, south of Khairpur, Jacababad, PPL’s Kandhkot Gas Field (1959)
Further Exploration OGDC’s Bobi Oil Field (1988) Upto 1993 > 92 Oil and Gas fields
33 Gas 39 Oil 20 Oil/Gas
PETROLEUM HISTORY Offshore
Exploration in the Indus offshore started in 1961 ( Sun Oil Company) three nearshore wells
Wintershall conducted 9400 km’s of 24 fold seismic survey (1969) drilled three wells
Philips petroleum Husky (USA) one well, Karachi south A-1
(1978)
PETROLEUM HISTORY 7 offshore wells, till 1978 In movable HCS
Unfortunate in offshore drillingDue to various reasons
Abnormal Pressure Irregular Temperature Immaturities
Summary Total wells 301 (Exploratory) since 1866 till
1992 290 Onshore 11 OffshorePakistan, one of less explored basins
Five wells / 10000 km2 (Pakistan) Twelve wells / 10000 km2 ( World Average)
Pakistan resulted in discovery of about 500 Mbbls of oil
31 Tcf of gas Untill 1993 In 1989, government of Pakistan
introduced the block/bidding system, 43 blocks were offered internationally
