GUWAHATIl: According to a report,Oil India Limited (OIL) has launched Airborne Gravity Gradiometry& Gravity Magnetics (AGG & GM) data for unapprised portions of Nagaland, Manipur, Mizoram, Dima Hasao, Arunachal Pradesh, Cauvery, Bastar, Satpura, Spiti-Zanskar, and Karewa districts.

GM and AGG survey acquisition reportedly began on May 27 from Jorhat Air Base.

The Ministry of Petroleum and Natural Gas' Directorate General of Hydrocarbons (DGH) charged OIL with collecting, processing, and interpreting (API) 40,000 flight LKM of AGG and GM data in these unapprised areas.

According to a source, the logistically challenging terrain, hostile environment, protected areas, and lack of in-principle permission for carrying out seismic survey operations under the National Seismic Programme (NSP) were some of the issues that prevented the seismic campaign from covering these areas.

Taking on twitter, Oil India Limited informed that, “#OilIndiaLimited entrusted by

@DghIndia @PetroleumMin the responsibility of Acquisition Processing & Interpretation (API) of 40,000 flight LKM of Airborne Gravity Gradiometry & Gravity Magnetics (AGG & GM) data in unapprised areas of Nagaland, Manipur …”

It also stated,” southern parts of Mizoram, North Cachar Hills, parts of Arunachal Pradesh, Cauvery, Bastar, Satpura, Spiti-Zanskar & Karewa areas. The acquisition of the AGG & GM survey began from #Jorhat Air Base on May 27, 2023, and the second aircraft is scheduled to start acquisition from Dibrugarh airport to cover the #northeastern part of #India.”

In order to reach the North East, the second aircraft is expected to begin acquisition from the airport in Dibrugarh.

The oil blocks awarded to Oil India Limited in Nagaland will also be included in the study. Up until the operations were halted in 1994, 75 oil wells in the Changpang and Tssori areas had been drilled and oil recovered on a trial basis. The anticipated reserves for the remaining oil the belt covers in Mokokchung are enormous. The other blocks include the districts of Dimapur, Peren, and Mon, where exploration has not yet been done.

Oil India Ltd. has received an oil exploration block from the Centre in Nagaland.

The AGG survey calculates the gravitational acceleration's spatial rate of change. The survey aircraft's sensors produce high quality images of the various components of the density contrast and measure five (5) separate components of the gravity field. The variation in the strength of the earth's magnetic field brought on by subsurface geology is measured by magnetics.
