A Novel Energy Lifting Approach Using J-Function and Flow Zone Indicator for Oil Fields

The X field is located in the southwestern part of block NX89 Kentan Basin Libya. This produced from Hailan multilayer consolidated sandstone with moderate rock property and a relatively low energy supplying. reserve subsurface sources declining years. Therefore, techniques were combined to achieve optimization increase hydrocarbon recovery. In order understand formation reservoir facilitate oil production, global hydraulic element technique was used quantify types. addition, stratigraphic modified Lorenz plot for layering. Reservoir heterogeneity identified using Dykstra-Parsons coefficient. Leverett J-function average 13 capillary pressure curves into four main represent whole based on flow zone indicator values. Capillary calculated plotted normalized water saturation; single curve defined rest curves. Water saturation multiple J-functions compared available logs. With J-functions, matching results good both high low-quality layers, whereas J-function, match poor, especially FZI layers such as H4c H6a. Four types this ranging medium quality six different obtained. heterogeneous coefficient value approximately 0.72 0.70. All approaches paper validated showed improved recovery factor.
