Surface Infrastructure

Commissioned in 2006



• Divided in to 3 sectors.

• Historically on tank production

Slide 5 of 43 20 /37



Gamij Stage Gate

• OIIP increased from 15MMt to 51MMt

• Oil production increased from 200 to 360tpd during last 3 years and

efforts to enhance it to 1000tpd

• Air injection pilot is to be implemented in Gamij Central and

envisaged recovery of 47%• Carried out fast track development drilling, HF jobs and well

interventions

• Strategies formulated for full fledged water / gas injection

• Surface facilities created by construction of EPS-III & EPS-II

Infill drilling for optimum exploitation for Kalol sands

Review of water injection for pressure maintenance for Kalol sands

by infill drilling and conversion of poor oil producers to water

injectors Development strategy for Chhatral sand including assessing the

requirement of water injection scheme

Chhatral Pay- Development Strategy

Chahatral OIIP – 35 MMt

Chhatral sand developed throughout of the field

Sand thickness is vary from 20m to 200m

Permeability in the range of less than 1 md to 10 md

Sand is on depletion drive

Well productivity only 2-3 m3/d

Cumulative oil production 0.113 MMm3 (as on 1.1.2014)

Recovery is around 0.33%

Sensitivity of well spacing and different water injection pattern

done

Development strategy needs cautious approach
