Well testing has been in place for over 50 years. The benefits of using this technology have been published in numerous technical articles. A popular method for pressure data interpretation has been published back in year 1950 by Horner and still today can be applied. Presently most of pressure transient analysis is carried out by commercial software which can handle quiet complex pressure data interpretation using analytical or numerical linear or non-linear solutions as well as considering permeability and porosity dependency on pressure for non-conventional reservoirs.
However, and in spite of testing technology and software development advances, pressure data interpretation and test design are not an automated technique, it requires of professional human intervention to be successful. Course main objective is to learn how to carry out a well test analysis and to know how derived results are used to identify in quite a fast way compared to other methods, the reservoir model associated to the drainage area of the well and to determine the parameters related to the reservoir flow capacity as well as the evaluation of present well productivity which are results derived from Pressure Transient Analysis (PTA)
- To provide participants with a sound understanding of both practical and advanced methods currently in use for pressure transient analysis
- Understand why, when and how to test a well and in the right way
- Understand the principles of fluid flow through porous media and Nodal analysis.
- Learn how to interpret pressure transient data acquired in both conventional or non-conventional oil or gas reservoirs
- Learn about pressure data quality control and well test design for exploratory and development wells
- Understand the application of well test analysis to evaluate reservoir and well parameters that are directly responsible of both reservoir and well performance
- Understand that results derived from pressure transient analysis are an added value in defining in quite a short time the Reservoir Model associated to the well’s drainage area
- Learn about current reservoir testing models that are used for pressure transient analysis and the expected pressure and derivative response
- Understand when to use either a linear or nonlinear analytical or a numerical solution for pressure data interpretation
