Making major operational decisions based on incomplete or inaccurate well data is a significant risk. In an industry where optimizing a single well can contribute to savings of up to $37,000 and improved field-wide testing can impact costs by tens of millions, the quality of information gathered during a well test is critical. Yet many standard testing procedures only scratch the surface, leaving valuable reservoir insights behind.

The challenge for operators is moving beyond routine data collection to a more strategic approach. This involves designing and executing tests that capture the subtle behaviours of the reservoir, providing a clear and reliable basis for production planning and investment. It requires a partner focused on meticulous field execution and high quality data acquisition. At Bakker Flow Services, we help operators achieve this by combining robust methodologies with practical, hands-on expertise in surface well testing.

Moving beyond standard tests to advanced methodologies

An “advanced” well test is not necessarily about using unproven technology; it is about applying a more sophisticated approach to test design, execution, and data acquisition. The goal is to isolate and understand specific reservoir characteristics that standard tests might overlook. By carefully planning the test sequence and using precise measurement techniques, we can gather data that tells a much richer story.

Here are a few methodologies that provide deeper insights:

Pressure derivative analysis

This is a powerful interpretation technique that helps identify different flow regimes, such as linear or radial flow, and diagnose near-wellbore conditions like skin damage or stimulation effects. While the final analysis is done by reservoir engineers, the validity of the derivative plot depends entirely on the quality of the raw pressure data captured in the field. A properly executed test minimises noise and provides the clean signal needed for this detailed analysis.

Multirate and injection tests

Instead of testing at a single flow rate, a multirate test involves a series of planned rate changes. Observing the well’s pressure response to these different rates provides a more dynamic dataset, helping to distinguish between reservoir boundaries and other flow barriers. Similarly, injection tests are crucial for evaluating the performance of water or gas injection wells, and the data they provide supports better field development strategies.

losed loop testing

For environmentally sensitive projects or specific operational constraints, closed loop testing provides a safe and contained method for flowing a well. This approach routes all produced fluids back into the flowline or production system, eliminating the need for flaring. It is an effective strategy for well clean-outs and performance testing while minimising environmental impact.

The foundation of reliable data is quality control in the field

The most advanced analytical models are only as good as the data they are fed. True expertise in well testing is demonstrated not just in the planning but in the meticulous execution on site. Minor errors in measurement or procedure can lead to misinterpreted results and flawed decisions. This is why focusing on the fundamentals of data acquisition is non-negotiable.

Several critical factors in the field directly impact data quality:

Managing wellbore storage effects

At the beginning of a test, much of the flow comes from the expansion of fluids already in the wellbore, not from the reservoir itself. This “wellbore storage” effect can mask the true reservoir response for a significant period. An experienced team can design the test and manage the flow to minimise this period, allowing for a quicker acquisition of usable reservoir data.

Ensuring accurate rate and pressure measurement

Consistent, high resolution data is essential. This requires using calibrated, reliable gauges and flow meters that are correctly installed and monitored throughout the test. Our real time data acquisition systems allow our field specialists to track test parameters continuously, making it possible to identify and address potential issues as they happen, rather than discovering them after the test is complete.

Strategic equipment configuration

The surface equipment spread must be tailored to the specific well conditions and test objectives. This includes selecting the right size and type of separator, choke manifold, and sand management equipment. For example, using a cyclone desander or sand filter protects downstream equipment and ensures that sand production does not compromise flow measurements. Our flexible approach allows us to provide the right rental equipment to build a safe and effective test setup for any scenario.

Turning field data into confident operational decisions

The ultimate purpose of any well test is to provide clear, actionable information. By focusing on advanced methodologies and rigorous quality control, we deliver data that empowers reservoir engineers and production teams to make better informed choices. Accurate measurements of permeability, skin, and reservoir pressure contribute directly to more reliable production forecasts and optimised field development plans.

This commitment to quality was recognised when Bakker Flow Services received the Best Supplier award in the Well Testing Category for EBN’s SCAN Drilling Campaign. It reflects our core focus on providing reliable field services that generate data our clients can trust. By handling the complexities of surface well testing, we enable our clients to concentrate on their core business of reservoir analysis and management.

Partner with an experienced team for your next well test

Successfully executing an advanced well test requires more than just equipment. It demands a partner with the field experience to manage complex operational challenges and a deep understanding of what constitutes high quality data. The right approach ensures that the data gathered is not just a set of numbers, but a reliable foundation for critical decisions that shape the future of your asset.
