Bugan field gas management controls four producing zones

The Bugan field was discovered in 1993 with first oil produced through the Iron Duke facilities in 2003. The field’s sandstone reservoirs were deposited in a lower shoreface environment and are faulted into twelve blocks; five blocks have been drilled. With the Bugan-7 well, early Bugan Main block development sought to reduce uncertainties from reservoir compartmentalization, reservoir deliverability and vertical communication. Bugan-7 was completed on four stacked oil rims: M20, M30, N10 and N50. Paino et al.1 assert that the data acquired using smart well technology reduced the range of key uncertainties of the block. Continuously acquired data for downhole pressure, zonal production rates and the well’s temperature profile enabled field engineers to build a calibrated subsurface model. Based on this model, the engineers established an optimum number and location of development wells and defined a Gas Management Strategy (GMS).
