Geothermal integration solutions as unconventional environment have workflows or methods that must be able to optimize existing data and be adapted to overcome existing challenges. The integration method consists of geology, Petrophysics and Geomechanics domains. Geological analysis to identify fractures, fracture classification, knowing the dip azimuth and the magnitude of the fracture, quantitative analysis (intensity, aperture and porosity) by using the wellbore image log. Petrophysics analysis is to distinguish open / healed fractures that analysed from sonic data. Fracture orientation analysed further for the stress calculation on fracture planes and to determine the effective fractures (most likely to flow) that has a high ratio of shear to normal stress. Geomechanical analysis in geothermal fields, among others, is to determine the dynamic permeability behaviour of fractures during the production / injection phase, determine the orientation and productive fracture interval. The integration is using FORGE well 21-31 in 8.5in section with depth interval 6,226 – 7,920 ft-MD and well 58-32 in 8.5in section with depth interval 7,390-7,527 ft-MD. Well 21-31 shows dominant fracture strike orientation to NNE-SSW, while Well 58-32 shows slightly different set strike orientation to NS with minor striking to NE-SW and NW-SE. Evaluation of critically stressed fracture intended to have knowledge on production mechanism and based on analysis, fracture/fault that has high potential of shearing is striking to NNE-SSW and dipping to Westerly.
