Petroleum & Natural Gas Secretary reviews progress at Baghjan oilwell
GUWAHATI: Tarun Kapoor, Secretary, Petroleum & Natural Gas reviewed the progress of work at the Baghjan oilwell, which blew out on May 27 and later into an inferno on June 9. Efforts are on to repair the damage.
Kapoor visited the site, along with the CMD and Functional Directors of OIL, to take stock.
He reviewed the progress and expressed his satisfaction on the execution. He held a detailed discussion with the District Administration and briefed them on the next course of action.
Kapoor talked with experts from M/s Alert Disaster Control, as well as V P Mahawar, Ex-Director (Onshore), ONGC and teams from OIL and ONGC to understand the plan of capping the well.
OIL said TERI has reported the mass production of biomaterial as having started. A truck load of microbes will be dispatched from their facility and expected to reach site by July 5.
“A broadband seismic network of five stations has been installed surrounding the blowout location to monitor seismic activity, if any. An accelerograph has been installed at Baghjan EPS to monitor ground tremors, if any and also to estimate the effects on the nearby area. Simultaneously, geophysical survey is being carried out with instruments, resistivity meter, proton precision magnetometer and VLF (Very Low Frequency) meters to understand subsurface activity. InSAR studies are being carried out to observe subsidence, if any. Analysis of data will be carried out in Jorhat and Hyderabad,” they said.
The company added that laying of 12 delivery line with the header of the pump has been completed. Connection of the delivery lines and other accessories is in progress.
“Fabrication of additional three number heat shields has been completed. Fabrication of heat shields for bulldozer and excavator is in progress. A team from Alert is inspecting the equipment at OIL CMT Yard with ONGC-CMT and an OIL Technical team before transferring to the site. Retesting of the choke manifold is in progress,” the company added.
OIL claims that a lot of important equipment/material is in transit. Consignments have been delayed due to a ban on the day-time movement of heavy vehicles. Due to a Bandh in Tinsukia, movement of men and material has been affected. The blockade on producing oil & gas wells has been lifted in a few areas on June 23. Blockades still continue at few other locations, affecting production. Blockades at a drilling location and one workover location have been lifted on June 23, while blockades still continue at another drilling location and three workover locations.
Due to stoppages/blockades, there was production loss of 103 MT of crude oil and 0.14 MMSCM of natural gas as reported on June 23. Operations have been disrupted in 15 oil wells and one gas well. Cumulative production loss since May 27 due to bandhs and blockades stands at 8394 MT crude oil and 0.7 MMSCM of natural gas, as reported by OIL.
