Handil Deep Zone (HDZ) is the backbone of gas contributor in Handil field, characterized by multi layered, highly compartmented and low permeability reservoir. Limited well data, risk of sand occurrence, depletion, and productivity are the main challenges for HDZ development. Hence, it is important to develop a robust geomodeling methods to minimize these uncertainties. Sedimentological concept is essential for predicting sand distribution orientation due to the absence of reliable seismic data. Dynamic data then used extensively to validate sand distribution, hydrocarbon accumulation, and reservoir compartmentalization. Furthermore, understanding behavior of depletion in low-permeability HDZ is crucial. Introducing a method to estimate pressure distribution as a function of distance active producer is one of the key elements in HDZ reservoir pressure prediction. Burial and compaction may lead to the productivity issue in HDZ. Perforation result statistic is used along with the kriging method to create map to highlight the area based on reservoir flow probability. Such flow prone map can be used as guidance on locating the best location for drilling new wells. Using all these approaches integrated in the latest geomodel enable us to locate the good pressure, good productivity and high probability of sand occurrence area so-called “sweet spot” for the future wells location.
