Integrated open-hole data interpretation technique in tight/deep invaded reservoirs
Abstract
Modular Formation Dynamics Tester (MDT) and Reservoir Characterisation Instrument (RCI) are commonly used in appraisal/exploratory wells. The results of the MDT/RCI method help clarify the hydrocarbon pay zone, determine reservoir pressures, oil/gas-water contact (OWC/GWC), as well as intervals for drill stem test (DST), and examine the properties of reservoir fluids. However, it is sometimes quite difficult to get acceptable results with reasonable measure time, especially in tight reservoirs with low fluid mobility or deeply invaded zones. The paper describes a methodology which allows the efficiency of obtained information to be improved by integrating different kinds of well data.
