India has important oil fields located in the states of Assam, Gujarat, and Maharashtra. India holds 4,728,790,000 barrels which are proven oil reserves as of 2016, which ranks around 24th in the world. Assam along with Gujarat, Rajasthan, and Mumbai High Field accounts for 96 percent.

An oil field is a lot of land utilized to remove oil, like gaseous petrol or raw petroleum, starting from the earliest stage. Although some challenge the specific starting points of oil, most believe petrol to be a “non-renewable energy source” made from dead natural material frequently tracked down in old seabeds a large number of meters underneath the outer layer of the earth. On-shore Oil Production. One-shore oil fields are situated in the Brahmaputra valley of northeast India, the Gujarat coast in western India, and the Cauvery on-shore bowl in Tamil Nadu. Other than Andhra Pradesh has both on-shore and seaward oil holds.

Oilfields in North-East India

The significant oilfields in northeast India are those of the Brahmaputra valley in Assam and its adjoining regions including Arunachal Pradesh, Nagaland, Meghalaya, Tripura, Manipur, and Mizoram.


Assam is the most seasoned oil-delivering state in India. The fundamental oil-bearing layers reach out for a distance of 320 km in upper Assam along the Brahmaputra valley. Following are a portion of the significant oilfields of Assam:

Digboi Field

Situated in the northeast of Tipam slopes in the Dibrugarh locale of Upper Assam, Digboi is the most established oil field in India. The oil-bearing layers cover an area of around 13 sq km where oil is accessible at 400 to 2,000 meters profundity. North 800 oil wells have been boring up until this point. Before the launch of the oil fields of west India, Digboi used to represent three-fourths of the all-out oil creation of India. The main places are Digboi, Bappapang, Hassapang, and Paintola. Most oil is shipped off the petroleum processing plant at Digboi.

Naharkatiya Field

It is situated a ways off 32 km southwest of Digboi at the left bank of the Burhi Dibing waterway. Here oil was found in 1953 and creation began in 1954. Oil is accessible at profundities shifting from 4,000 to 5,000 meters. Out of the 60 effective wells bored up to this point, 56 are delivering oil while the leftover 4 are creating gaseous petrol.

The yearly creation is 2.5 million tons of oil and 1,000,000 cubic meters of petroleum gas. Oil from this area is shipped off petroleum treatment facilities at Noonmati in Assam (443 km) and Barauni in Bihar (724 km) through the pipeline.

Moran-Hugrijan Field

It is situated around 40 km southwest of Naharkatiya. Oil at the Moran-Hugrijan field was found in 1953 and creation began in 1956. Penetrating has demonstrated an oil-bearing Barail skyline at a profundity of 3,355 meters. Moran s potential might be assessed at 1,000,000 tons for every annum. Upwards of 20 wells have been penetrated which yield oil as well as gas.

Different fields have been found at Rudrasagar, Sibsagar, Lakwa, Geleki, Badarpur, Barholla, and Anguri. The oilfields of Assam are somewhat out of reach and are indirectly situated from the super-consuming regions. Oil from Assam is, hence, refined generally in the processing plants situated at Digboi, Guwahati, Bongaigaon, Barauni, and Nomaligarh. Arunachal Pradesh has oil holds at Manabhum, Kharsang, and Charali. In Tripura, promising oilfields have been found at Mamunbhanga, Baramura-Deotamura Subhang, Manu, Ampi Bazar, and Amarpur-Dambura regions. Nagaland likewise has some oil-bearing stone layers.

On-Shore Oil Fields of Western India

The on-shore oil fields of Western India include the following:


Investigations by the Oil and Natural Gas Commission (ONGC) have yielded important discoveries of oil-bearing stone layers over an area of around 15,360 sq km around the Gulf of Khambhat. The primary oil belt stretches out from Surat to Amreli. Kachchh, Vadodara, Bharuch, Surat, Ahmedabad, Kheda, Mehsana, and so on are the principal delivering regions.

In 2002-03, Gujarat created north of 60 lakh lots of raw petroleum which represented more than 18% of the complete oil creation of India. Ankleshwar, Lunej, Kalol, Nawgam, Kosamba, Kathana, Barkol, Mehsana, and Sanand are the significant oilfields of these locales.


The principal significant oil find came in 1958 with the disclosure of the Ankleshwar field situated around 80 km south of Vadodara and almost 160 km south of Khambhat. Ankleshwar anticline is around 20 km long and 4 km wide. Oil is accessible at profundities changing from 1,000 to 1,200 meters. It has a limit of 2.8 million tons for every annum.

It is such a productive oilfield that Pt. Jawahar Lal Nehru called it the wellspring of thriving. Upwards of 170 oil wells have been exhausted up to this point. It is assessed that 25 lakh tons each extended time of oil can be gotten from this field. Oil from this field is shipped off treatment facilities at Trombay and Koyali.

Khambhat or Lunej Field

The Oil and Natural Gas Commission penetrated test wells in 1958 at Lunej close to Ahmadabad and affirmed the event of a financially exploitable oil field. Oil was gotten on the fourth Sept. 1959. Till 1969, a sum of 62 wells was penetrated out of which 19 yielded gas while 3 yielded oil. The yearly creation is 15 lakh lots of oil and 8-10 lakh cubic meters of gas. The all-out saves are assessed at 3 crore tons.

Ahmedabad and Kalol Field

It lies around 25 km northwest of Ahmedabad. This field and a piece of Khambhat bowl contain ‘pools’ of weighty rough caught in lumps of coal. Nawgam, Kosamba, Mehsana, Sanand, Kathana, and so forth are significant makers. Oil has likewise been struck in Olkad, Dholka, Kadi, Asjol, Sandkhurd, Siswas, Nandesan, Bandrat, Sobhasan, and Vadesar regions.


One of the biggest inland oil revelations was made in the Banner region of Rajasthan in 2004. The oil block covers an area of around 5,000 sq km. Best-in-class innovation with the imaginative land demonstration was utilized in finding this oil field. Beginning assessments of the oil instead of this disclosure range from 63 to 153 million tons.

Western Coast Off-Shore Oilfields

Broad overviews have been directed by ONGC in the seaward areas of Kutch, Khambhat, Konkan, Malabar, and Coromandel coasts, Krishna-Godavari delta, and Sundarbans. Accomplishment on a business scale has been accomplished at Mumbai High, Bassein, and Aliabet.

Mumbai High

The best achievement accomplished by the ONGC for seaward overviews for oil was that of Mumbai High in 1974. It is situated on the mainland rack off the shore of Maharashtra around 176 km northwest of Mumbai.

Here the stone layers of the Miocene age cover an area of 2,500 sq km with assessed stores of around 330 million tons of oil and 37,000 million cubic meters of petroleum gas. Creation on a business scale started in 1976. Oil is taken from a profundity of more than 1,400 meters with the assistance of an exceptionally planned stage known as Sagar Samrat.


Situated toward the south of Mumbai High, this is a new disclosure blessed with saves that might end up being higher than those of Mumbai High. Colossal stores have been found at a profundity of 1,900 meters. Creation has begun and is supposed to get quick.


It is situated at Aliabet Island in the Gulf of Khambhat around 45 km off Bhavnagar. Immense stores have been tracked down in this field. An amount of Rs. 400 crores has previously been spent on this field. Business creation is supposed to begin soon.

East Coast

The bowl and delta locales of the Godavari, the Krishna, and the Cauvery streams hold incredible potential for oil and gas creation. As such these are both on-shore and seaward regions where broad investigation has been led during the most recent couple of years. The Ravva field in Krishna-Godavari seaward bowl is supposed to every year create 1 to 3 million tons of raw petroleum.

Andhra Pradesh creates short of one percent of the absolute unrefined petroleum of India. Oilfields have as of late been found in the Krishna-Godavari bowl. The oilfield close to Amolpur is supposed to yield 3,600 barrels of raw petroleum each day.
