    Baghjan Blowout: Well Killing Fluid Ready, Waiting for Core Team nod

    The final operation to kill and capping of the well got disrupted when three foreign experts sustained burn injuries while working on controlling the blaze

    Guwahati: The final operation to kill the Baghjan blowout well in Tinsukia has reached a significant stage as the well killing fluid has been readied to be transferred to site subject on Monday.

    It was waiting for receiving signal from Core Technical Team at site, said the OIL authority.

    A well kill is the operation of placing a column of heavy fluid into a well bore in order to prevent the flow of reservoir fluids without the need for pressure control equipment at the surface. It works on the principle that the hydrostatic head of the “kill fluid” or “kill mud” will be enough to suppress the pressure of the formation fluids.

    Last week the final operation to kill and capping of the well got disrupted on Wednesday when three foreign experts sustained burn injuries while working on controlling the blaze.

    Though there were reports of an explosion at the site, OIL later denied of it.

    On Monday, the OIL authority informed, “The final preparation for capping operation has been active. New studs have been transferred to the site for replacing the deformed and damaged studs of the lowermost casing head housing flange.”

    Already the seismological recording in the vicinity of the blowout well by the Council of Scientific and Industrial Research -North East Institute of Science & Technology (CSIR-NEIST) has been completed.

     Assam government had asked CSIR-NEIST experts to conduct a study of the repeated tremors felt in the vicinity of Baghjan area where a natural gas well caught fire after a blowout.

    The gas well located at Baghjan had witnessed a blowout – an uncontrolled release of gas or oil – on May 27 and caught fire on June 9, when two firefighters were killed and destroyed several adjoining villages.
