What are the main objectives of well test analysis?
The objectives of a well test usually fall into three major categories: (i) reservoir evaluation, (ii) reservoir management, and (iii) reservoir description..
What are the objectives of well test?
Well tests are performed throughout the life cycle of a reservoir to accomplish large numbers of important objectives and gather invaluable information, such as formation transmissibility and storativity, average reservoir pressure, evaluation of deliverability of gas producers, well condition including liquid holdup .
What is test analysis and design?
The Test Analysis and Design phase involves a review of the test basis and the identification of test conditions.
Let us take a closer look at both these activities.
Review of the test basis includes a review of product requirements, architecture, design specifications, and interfaces between the products..
What is the basic well test analysis?
Basically, well test analysis deals with the interpretation of the wellbore pressure response to a given change in the flow rate (from zero to a constant value for a drawdown test, or from a constant rate to zero for a buildup test)..
What is the purpose of well test analysis?
Well test analysis provides information on the reservoir and on the well.
Geological, geophysical and petrophysical information is used where possible in conjunction with the well test information to build a reservoir model for prediction of the field behavior and fluid recovery for different operating scenarios..

What is the well test method?
During well tests, reservoir fluids are produced to the separator at varying rates according to a predetermined schedule.
These tests may take less than two days to evaluate a single well or months to evaluate reservoir extent.
Test types include buildup, drawdown, falloff, injection and interference..
- One of the main challenges for horizontal well testing and analysis is to identify and characterize the different flow regimes that occur along the wellbore and in the reservoir.
Flow regimes are the patterns of fluid flow that depend on the pressure gradients, fluid properties, and well geometry. - The objectives of a well test usually fall into three major categories: (i) reservoir evaluation, (ii) reservoir management, and (iii) reservoir description.
- Well testing is one of the most valuable tools used by reservoir engineers.
It is routinely used to evaluate well and field performance, diagnose reservoir characteristics, integrate test results with other studies, plan for future development, and perform the overall management of the reservoir.
