Course Description

This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops. This course is designed to provide participants with a basic and up-to-date overview of pressure transient analysis/rate transient analysis (PTA/RTA). It covers the basic theory of diffusion PTA/RTA; the basic principles and terminology governing both methods; the Darcy?s law and the equation of state leading to the diffusivity equation; the principle of superposition, infinite-acting radial flow, wellbore storage and skin and pseudo-steady state; the PTA methodology from the simple straight line horner to the current modelon-the-fly bourdet derivative; the quality control process before making an analysis; and the basic Saphir features including the interpretation path of load, edit, synchronizing, model, classical methods, derivative and the application to field examples. Further, the course will also discuss the well models comprising of vertical wells, skin, finite/infinite conductivity fractures, limited entry and horizontal wells; the reservoir models covering homogenous and heterogeneous models behavior including 2?, 2? and composite; the boundary models that include single limit, intersecting, parallel faults and closed system; and the typical errors encountered when diagnosing a boundary effect with an illustration of superposition effects and the influence of production duration on the analysis.During this interactive course, participants will learn the use of pseudopressures and multiple period analysis for rate dependant skin; the IPR AOF options in Saphir and the connection to the amethyste WPA module; the test objectives and designing a test to achieve them; the methodology from the basic empirical methods including Arps and Fetkovich to the current modern Blasingame, material balance and loglog diagnostic plots; the basic Topaze features including the interpretation path of load, edit, model, p(q), q(p), fast model and application to field examples; the principle of the linear (single phase) numerical model and how to build a model; and the well type, composite zones, faults and thickness.
