Chhatak Gas Field () is a natural gas field located in Chhatak Upazila, Sunamganj District, Bangladesh. This company is under the control of Sylhet Gas Field Company Limited (SGFL). For the first time in Bangladesh, gas connection was provided to the industrial sector from this gas field in 1959. In 1960, it provided approximately 4 million cubic feet of gas per day to Chhatak Cement Factory as well as Sylhet Pulp and Paper Mills.
Location Chhatak gas field is located in Chhatak Upazila, Sunamganj district of Sylhet Division, about 300 km northeast of the capital Dhaka. This gas field is basically operated as two different gas fields - Chhatak (East) and Tangrtila or Chhatak (West) - which were merged into a single field after 2001.
Accidents
The field, also known as Tengratila, was the site of two major gas well blowouts in 2005, both occurring while the Canadian company Niko Resources was drilling an exploratory well under a joint-venture agreement with Bapex. The first blowout, on 7 January 2005, was attributed to a failure to case a loose sand formation before the drill string was withdrawn. A second, larger blowout occurred on 24 June 2005 while a relief well was being drilled to divert gas from the still-leaking first well, producing a fireball estimated at high.
An environmental impact assessment found extensive damage to homestead forest, wildlife and groundwater in the surrounding area, and the incident led to a foreign-bribery scandal in which Niko gave a Bangladeshi state minister a vehicle and paid for his overseas travel, resulting in a 2011 guilty plea and fine in a Canadian court. Bangladesh and Bapex sought roughly in compensation through arbitration at the International Centre for Settlement of Investment Disputes; in December 2025, the ICSID tribunal ordered Niko to pay .
