The Oil and Natural Gas Corporation (ONGC) has found another gas reservoir of nearly 726.6 MW capacity near Palatana combined cycle gas turbine (CCGT) based power project in south Tripura last week. The ONGC authorities had not yet officially announced the success, but admitted that at least 1.5 lakh cubic metres gas would be found from the site, which would increase the business prospect of the company in this landlocked part of the country as well as help the smooth functioning of Palatana power project. ONGC officials said the exploration commenced from Tulamura under Belonia subdivision from the first week of June as the requirement of natural gas had increased because of upcoming thermal plants at Palatana in South Tripura and Monarchak in West Tripura and expansion of existing plants in Barmura and Rokhia. The exploration team found gas reservoir after drilling about 2500 metres in the area followed by discovery of reserve in Tulamura at about 3200 metres deep last month. The ONGC has as many as 70 gas wells in Tripura at present. Earlier, ONGC found a huge deposit of hydrocarbons in the exploratory well at remote Sundalbari area along Indo-Bangladesh border in West Tripura where the drill was initiated in April 2008 and gas flowed from two sand formations at 85,000 and 80,000 cubic metres per day. According to the report, Sundalbari-2 exploratory well was a nomination block of ONGC and the geological inputs and earth crust had drawn the attention of the company some three years ago but procedural bottlenecks delayed the discovery. According to UNI report, the ONGC had found gas at Kunjaban, within seven kms periphery of the capital town in May and the exploratory well had a flow rate of 2.3 lakh cubic metres through conventional testing methods. It has already established approximately 54 billion cubic metres of in-place gas reserve from seven fields (excluding Kunjaban and Sundalbari) identified in the state and the recoverable reserve was pegged at 28 billion cubic metres. ONGC has already established recoverable gas reserves in Baramura, Gozalia, Manakyanagar, Agartala Dome, Trichina and two other spots in West Tripura but the work resumed in Baramura hill range after a long break, which was stalled due to militant activities. The company has announced to go for large-scale exploration work in Tripura with the increasing investment scope in power sector and medium-scale industries in the state. Mumbai-based Allied Regence and Chemicals and Kolkata-based another group have also placed an order for natural gas to set up a methanol project in the state, which prompted ONGC to enhance the exploration plan. ‘’Taking into consideration the set of demands we have agreed to meet, we will need to supply six million cubic metres of gas and we are preparing for it by drilling new wells,’’ said a senior official of ONGC Tripura Asset, adding ONGC would dig 120 new wells in different parts of the state over the next few years and at least half of them were likely to yield gas. According to the report of Geo-chemical survey, about 52 billion cubic metres of natural gas could be found underground in the state and followed by this ONGC had prepared a special programme called Vision Mission Six million to augment natural gas production.
