The oil and gas business is critical to today's economy since petroleum and natural gas continues to be the central supply of energy for people and buildings, as well as the primary source of materials for many interconnected industries. Considering this fact, the most constructive way to find crucial information is to run frequent & various kinds of tests in the oil and gas industry. For a variety of reasons, testing on oil and gas wells can be done at different stages of the drilling, completion, and production process. Production well testing in oil and gas is carried out to determine how productive a well is and to analyze its flow capacity under certain reservoir and flowing pressure conditions.
Kinds of Production Well Testing
Initially, wells were tested using the "absolute open flow" technique, which was widely despised in the industry due to environmental and safety concerns. To mitigate these hazards, the oil and gas sector began testing with controlled flow rates, using the "conventional back pressure test" method. Few well testing methods are discussed below:
1) Drill stem tests (DSTs) are used to obtain:
- fluid samples from the reservoir,
- static bottom hole pressure measurements,
- an indication of good productivity,
- shorter flow and pressure buildup experiments that can be used to determine permeability and the level of damage or stimulation
2) Single-point Test:
These well tests are typically basic productivity tests that entail measuring (or estimating) initial or average reservoir pressure, flow rate, and flowing bottom hole pressure (which can be calculated from flowing surface pressure) at stabilized production occurrences.
3) Multi-point Test:
These tests calculate gas well deliverability and absolute open flow potential. Gas well deliverability tests, backpressure tests, and flow-after-flow tests are all terms used to describe this production flow test.
4) Swab Tests:
It is described as the removal of a full-diameter tool from the wellbore; this pulling motion is comparable to that of a syringe plunger, and it commences fluid flow into the wellbore.
Improper Testing's Financial Consequences
It’s always advised by professionals to appropriately check the financials against the tests for oil well testing and production allocation. In terms of regulatory compliance and enforcement, corporate reputation, and potential financial loss, business processes and field level procedures frequently pose significant business risks. Improper testing can have the following costly consequences:
- Suspension of the facility as a result of enforcement action,
- For low-gas-producing wells, test frequency exceeds regulatory requirements.
- Overpayment of carbon taxes is a possibility,
- Due to the over-reporting of gas production volume, royalties will increase.
- Over-sizing of gas gathering equipment (compressors, pipelines, etc.)
