The Beanibazar-1(BB-1) is located about 15 kilometers east of the Kailashtila Field on a seismically defined structure of Late Tertiary (Pliocene/Pleistocene) age. This well was drilled under Multi Well Drilling Project (MWDP) in the eastern part of Surma sub-basin, Bengal Basin, Bangladesh. The Beanibazar structure is a symmetrical anticline having a north-south extension of about 12 kilometers and east-west extension of 7 kilometers. The well was spudded-in on 20th November 1980 and the drilling was completed on 12th May 1981. The total depth (TD) reached at 13,480 feet (4108.70m).

Beanibazar-2 (BB-2) well was drilled under the Second Gas Development Project (SGDP). The well was spudded-in on 21st March 1988 and the drilling was completed on 16th July 1988 at a total depth (TD) of 12048 feet (3672.23m).

The trial production started on 13th May 1999 and the field went into commercial production from 31st July 1999.

A 60 MMSCFD Solid Desiccant Silicagel type process plant has been relocated from Feni Gas Field and installed at the location of BB-1 in this field.
