DE0280 : Advanced Well Testing Design & Analysis

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.Well testing is a dynamic process. At its simplest, a test discovers if a formation can flow and permits sampling of the produced fluid. Analysis can yield further information like the extent of formation damage near the borehole, reservoir permeability and heterogeneity, and initial productivity index. For this, engineers induce pressure transients by changing the rate that formation fluids enter the borehole and recording the resulting downhole pressure versus time. Transient tests can also reveal the reservoir?s areal extent and vertical layering.Designing well tests involves many of the same steps the interpreter uses. This is because once a test has been proposed, both the pressure data and the data?s interpretation can be simulated to show that the test as designed meets it?s goals ?design simulation requires estimates of formation and fluid parameters from nearby wells or the well in question. By predicting the likely shape of the log-log ?p and derivative curves, the engineer can demonstrate the feasibility of detecting and characterizing the anticipated reservoir features. For example, design simulation ensures that wellbore storage does not smother the feature being sought and guarantees a test that is long enough to view suspected reservoir boundaries. Another important feature of simulation is determining the accuracy and precision required of the pressure gauges. The design phase not only maps out the mechanics of a test, but also ensures that once underway objectives are met.This is an advanced level seminar designed for petroleum and reservoir engineers who may be required to design and/or interpret non-routine well tests. Participants will be introduced to a systematic approach to well test analysis and will apply it using modern well test analysis software. Numerous data sets with non-ideal behavior will be reviewed and analyzed to allow participants to gain experience with real world problems. Participants will be able to apply their newly acquired skills in their job assignments immediately upon seminar completion. A well test that achieves the objectives is not accomplished by accident. A well test design is a planned activity that uses the pre-test well/reservoir information to reduce the risk of wasting test money. By coupling the well test design service with the real-time operations (RTO) service that monitors and analyzes the test data in real-time, the success of a well test is greatly enhanced. The seminar provides many examples from all over the world which are used to illustrate the various techniques. Participants will take from the seminar clear and systematic methodologies to tackle the more demanding types of well test commonly encountered.
