Oil India Limited (OIL) is the second largest hydrocarbon exploration & production (E&P) Indian public sector company and operational headquarters in Duliajan, Assam, India under the administrative control of the Ministry of Petroleum and Natural Gas of the Government of India. However, Company's Corporate office located in Noida in New-Delhi-NCR region. OIL is engaged in the business of exploration, development and production of crude oil and natural gas, transportation of crude oil and production of liquid petroleum gas. The story of Oil India Limited (OIL) traces and symbolises the development and growth of the Indian petroleum industry. From the discovery of crude oil in the far east of India at Digboi, Assam in 1889 to its present status as a fully integrated upstream petroleum company, OIL has come far, crossing many milestones. The Company presently produces over 3.6-3.8 MMTPA (million tonnes per annum) of crude oil, over 7 MMSCMD of Natural Gas and over 50,000 Tonnes of LPG annually. Most of this emanates from its traditionally rich oil and gas fields concentrated in the Northeastern part of India and contribute around 80% of total Oil&Gas produced in the region. The search for newer avenues has seen OIL spreading out its operations in onshore / offshore Orissa and Andaman, Cauvery offshore, Tamil Nadu, Arabian Sea, deserts of Rajasthan, onshore Andhra Pradesh, riverbeds of Brahmaputra and logistically difficult hilly terrains of the Indian state Mizoram and Arunachal Pradesh. In Rajasthan, OIL discovered gas in 1988, heavy oil / bitumen in 1991 and started production of gas in 1996. The company has accumulated over a hundred years of experience in the field of oil and gas production, since the discovery of Digboi oilfield in 1889. It is possibly the only company to do so. From well completion to wellbore servicing, installation, operation and maintenance of modern surface handling facilities, the company has the skill and expertise to manage the entire range of operations required for onshore oil and gas production.
The company has over 100,000 square kilometres of license areas for oil and gas exploration. It has emerged as a consistently profitable International company and present in Libya, Gabon, Nigeria, Sudan, Venezuela, Mozambique, Yemen, Iran, Bangladesh and USA. OIL has recently emerged in the offshore giant gas-field project of Mozambique and also made discovery of oil & gas in Gabon as an Operator and Libya as non-operator. OIL acquired Shale oil asset in USA during 2012.
In recent years, OIL has stepped up E & P activities significantly in the North-East India. OIL has set up the NEF (North East Frontier) project to intensify its exploration activities in the frontier areas in North East, which are logistically very difficult and geologically complex. Presently, exploration activities are in progress along the Trust Belt areas of Arunachal, Assam including Mizoram. The Company operates a crude oil pipeline in the North East for transportation of crude oil produced by both OIL and ONGCL in the region to feed Numaligarh, Guwahati, Bongaigaon and Barauni refineries and a branch line to feed Digboi refinery.
Oil India History
A 1157 kilometres long fully automated telemetric pipeline with 212 kilometres of looping having a total capacity to transport over 6.0 MMTPA remains the lifeline of the Company. Commissioned in 1962, the double skinned crude oil pipeline traverses 78 river crossings including the mighty Brahmaputra River meandering through paddy fields, forests and swamps. There are 11 pumping stations, 18 Repeater stations and two terminal at Numaligarh and Rongapani. The engines that drive the giant pumps along the pipeline have crossed over two hundred thousand hours of service and established a world record of machine run - hours.
The Company is currently in the process of constructing a 660 km long Product Pipeline from Numaligarh to Siliguri. The Pipeline is expected to be completed by mid-2007. OIL also sells its produced gas to different customers in Assam viz. BVFCL, ASEB, NEEPCO, IOC (AOD), and APL and to RSEB in Rajasthan. The company also produces Liquefied Gas (LPG) in its plant at Duliajan, Assam.
