Nido Petroleum noted that Gaffney Cline and Associates (GCA) have completed their independent review of the Galoc oil field, updating the reserves certification with the information obtained during the development drilling and well testing.
Joanne Williams, Nido’s Deputy Managing Director said, "The data acquired during the drilling of the pilot well and the two horizontal production wells were very encouraging and we are now very pleased that GCA has confirmed our expectations of the Galoc oil field's productive potential. Not only has the low side moved significantly closer to the previous 2P best estimate of the potential in the Galoc 3 and Galoc 4 areas, but the increase in the 3P reserves (which is included in the Phase 2 development) has highlighted the upside potential
The petroleum fiscal regime in the Philippines is one of the best in Asia offering a favorable contractor take and numerous other fiscal incentives. These include a generous cost recovery mechanism allowing the contractor to recoup past costs prior to Government allocations. Given that the Galoc oil field development has a large cost recovery pool the resulting production will realise very high profitability metrics per barrel of oil produced, which
In mid-2006, Nido commissioned GCA to undertake an independent reserves certification of the Galoc oil field to support Nido’s investment decision. There was significant uncertainty in the reserves at that time as the field was not fully appraised. Since the 2006 update, there has been considerable new information gathered from the field, most importantly from the pilot hole and the two development wells.
The pilot hole was drilled in the south of the field through to the oil-water contact. The pilot hole was fully wireline logged (and pressure tested) and enabled recovery of reservoir rock cores and reservoir fluid samples to surface for detailed testing and analysis.
Galoc-3 and Galoc-4 were both drilled as long, horizontal production wells (1,300 and 1,600m long, respectively) through the middle of the oil column and targeting the best reservoir. Logging while drilling (LWD) was conducted and the wells were both flowed to surface to clean out the drilling fluid, gather oil assay samples and generate indications of flow potential.
Phase 2 Development Decision
Forthcoming Galoc production is critical to calibrate and confirm the modelling completed recently by GCA. After sufficient production history has been gathered from the Galoc 3 and 4 wells, these models and reserves will be updated once again. Nido’s final investment decision on a Phase 2 development of Galoc will be dependent upon this modelling exercise.
