Experience with in situ combustion pilot in presence of edge water
- Institute of Reservoir Studies, Ahmedabad (India); and others
This paper deals with the three-year performance of the in situ combustion process in the presence of edge water in Balol heavy oil field. This field forms an integral part of the heavy oil belt in the northwestern part of intra-cratonic rift graben of Cambay basin. The reservoir is a homocline with a dip in the range of 5-7{degrees} and has an edge water support. The depth of formation is about 1050 m; the oil has a gravity of 15.5{degrees}API, and a viscosity of about 150 MPa-s (150 cp) at reservoir temperature of 70{degrees}C and pressure of 10.24 MPa (104.4 kg/cm{sub 2}). The in situ combustion process was initiated at pilot scale in this field in March 1990 and is presently under operation. It is an inverted five-spot pattern of 2.2 ha in size. The process has resulted into significant increase in oil production and reduction in water cut from pilot as well as offset wells.
