With the growing demand for natural gas and oil production, it has become an economic necessity for making constant improvements in operational techniques with oil production. If the wells stimulation, installation of large equipment for oil production, and initial pressure maintenance are made wrong, the project’s expense can increase unnecessarily. The operator can make the wrong decision without having enough individual well data to analyze them.
Thus, production testing for a well is conducted to reduce the lack of ability or intelligence in engineering or management during fluid production. The major reasons for production well testing are regulatory requirements, economic stats, reservoir management, production management, etc. Let’s get to know about its application and how the testing is conducted.
What is the application of production well test data?
Production well test data is applied for calculating production well test volumes and rates and other significant measurements and back allocation. The production testing for the well also extracts data which can be helpful during validation and update of the well-flow models and virtual flow metering. Once the well-drilling is done, the reservoir is equipped with surface and sub-surface facilities to start production well testing.
It helps in producing the flow rate of the well. The testing can also be applied on old oil wells which are still in production to identify whether the wells are still efficient enough to produce fluid. There might be many factors that arise, which should be seen in the short-term or long-term so the well can successfully produce fluid for a while.
The production well testing is one of the most crucial applications in petroleum engineering, which determines the causes of problems that might or must have occurred in the wellbore, in the case of both oil reservoirs and gas reservoirs. Once the production testing is carried out properly, the operator can analyze the result accordingly and obtain much valuable information such as fluid permeability, fluid formation damage, repairing around the wellbore, which might have caused during drilling or fluid production, reservoir pressure, reservoir boundaries, and the well’s drainage radius, etc.
How is the well-test production conducted?
Before conducting production testing for the well, the operator needs to prepare the well for testing. For some tests, the well has to put under normal operation for at least 24 hours before the test, and in some cases, the well needs to shut in prior to the production testing to build up pressure. After the testing initiation, all the measurements were done in order to validate the data and rate calculation for the separator, multiphase flow meter, and production well test systems.
Production well testing plays a vital role in a reservoir and petroleum engineering. With the combination of well testing and production logging, you can extend the well’s production life.
