What should you know about well testing before hiring a well testing service?

There are many types of well-tests available, which helps in giving out information regarding properties with reservoir characterization. Well-testing can be performed on horizontal wells, hydraulically fractured wells, or naturally fractured wells in reservoirs. This testing produces a large scale of information that is achieved from well-test data. In the case of wells in a reservoir, a single well might require much testing while other wells require monitoring of pressure, changing rates. All these tests help the well-operator to understand the field more as the project develops.

What is well testing and why it’s done?

Well-testing analysis helps in extracting information regarding the well from pressure and rate data while producing a well. Well-test analysis is essential to obtain information on both wells and reservoirs. In the case of wells, the well testing measures the permeability rate and well damage or stimulation, otherwise known as the skin effect. However, in a reservoir, the testing informs about fluid presence, average reservoir pressure, reservoir heterogeneities, reservoir hydraulic connectivity, distances to boundaries, etc.

How is the well-testing analysis done?

To perform well testing analysis, the analyst first selects a period at a constant rate of fluid build-up. Then they plot some function of pressure against time to identify the flow regimes, e.g., radial, linear, spherical, etc. The flow regime is then included in an interpretation model. This helps in reproducing the pressure given the flow rate, which can work the other way around too. The well-testing analyst makes sure that the interpretation model is accurate and consistent with all the other aspects of the information, such as geological, seismic, or cores studies, etc.

What is the benefit of doing a well-testing analysis?

The common advantages of well testing are that the study allows you to properly assess the well’s condition and estimate reservoir parameters. With the implementation of new well-testing analysis techniques, the testing can achieve more accurate and better results. Thus, it makes a potential contribution to gain better reservoir knowledge and reservoir hydraulic connectivity.

Other than that, with proper well testing, you can ensure proper well water maintenance to not let the fluid dry up and have an adequate water flow consistency. If you experience drought, occasionally performing annual well testing is vital. Whether it’s water or any other fluid, it’s crucial to know their quality if they are consumable or not and prevent contamination.

Now that you know how well testing can help you, hire professional service providers to help you learn about the well’s condition to save you more time and money on making incorrect diagnoses and repairing. Get in contact with Wesco to get professional help for gas and oil well production testing.
