Oil Well Testing (and Oil and Gas Production Allocation Software Simplified…)

Testing wells is an essential part of any pumping operation. Whether it’s oil well testing to be eventually input into your oil and gas production allocation software or a simple well tests sheet, you’re probably going to spend a fair bit of time around the lease performing tests of different sorts.

Oil and other products of the well need to be tested before they’re sold, as well as to determine the effectiveness of things like chemical treatment. Other oil and gas well testing procedures may need to be performed on meters, valves, and other equipment around the lease.

Testing Wells

The well itself will need to be tested, both as it is brought into production and regularly throughout its life. Accurate testing and competent reading of the results can help improve efficiency and provide vital information for managing your operation. Each test is used for a specific purpose (ex: production allocation), so understanding how each works and what exactly is being tested is also important.


Prepping The Well For Testing

Before a well can be tested, it needs to be prepared. In this case, the preparation consists of putting the well in the right state to be tested. For some oil well testing, that will require at least 24 hours of normal operation before the test. Other oil and gas well testing requires the well be shut in before the test, so that it can build up some pressure.



Normalizing a well merely means that it is operating and producing in a standard way for that well, and has been doing so for at least 24 hours. When tests need this sort of preparation, you’re usually measuring, in some way, how the well is performing on a regular basis.

It seems like this should be fairly straightforward; hopefully wells are operating at ‘standard’ production rates most of the time. However, that does mean the well can’t be experiencing any reductions in production from faulty equipment, mis-set valves, and other common problems. If the production measured after normalizing isn’t close to the estimated production, it can mean that there is a problem somewhere.

Normalizing is particularly important when a well has been out of service for any amount of time. The well may have built up additional pressure, which will lead to a temporary increase in production. That increase can potentially last for several days, falling gradually over time. The first day the well is producing again, it may produce an additional quarter day’s production over the standard production. That over-production will fall, but measurements taken right after a well has been brought into service will not reflect the well’s daily production.


Shutting In

There are some cases where you do want to measure the production after the well has built up that additional pressure. For those tests, the well should be shut in for some length of time. ‘Shutting in’ is the process of isolating the well. The master valve and casing valves should both be closed, so that nothing is produced from the well. Any other lines, for example from a chemical injector, that lead to the well should also be closed at a valve. The wellhead should be quiet once the well is shut in; any noise most likely means you missed a valve or that one is leaking.

The standard shut-in time is at least 24 hours before you plan the test. However, that time period can vary, depending on the behavior of the well. The goal is for the well to reach its maximum pressure, which will most likely be learned from experience. When the well is first shut in, the pressure will rise rapidly. As time goes on, the increase will slow, eventually stopping and leveling off at the highest pressure. Wells that draw from formations with a higher porosity, for example in coarse sandstone, are likely to build pressure much more quickly. Formations with lower porosity will most likely need a longer period to reach max pressure.


Prepping The Tank Battery For Testing

Though you’re testing a well, the tank battery may need to be prepped also. Obviously, the tank battery should be able to accept a standard day’s production without a problem. Shutting the well in may require some adjustments at the tank battery. When the well is brought back into production, you should be sure the tank battery is ready to accept the over-production that is likely to follow. Test production from the well will most likely need to be routed into the test separator, and then the oil will be sent to a stock tank so it can be measured; the gas should be metered, and the water volume should also be measured.

Testing Wells

Figure 1. An example of a separator used for testing.

Many tank batteries, particularly in smaller single well operations, may simply route both the water and oil through the test separator into the main/only stock tank. While the stock tank probably already has a fair bit of oil in it, it’s possible to figure out what’s been produced during the test easily. Just measure the amount of fluid in the tank before the test, and then again afterwards. Simple subtraction gives the amount of fluid produced in the test.

Once the total volume has been determined, you’ll want to find out what the ratio of oil to water that was produced. You can find this out by thiefing the tank; in other words, using a tool called a thief to take a sample from the tank at the estimated oil-water interface. Again, you’ll want to thief the tank before the well begins testing, and again after the test has been completed. A little simple math is all that’s required to find the produced oil volume. You’ll also want to find out the percentage of sediment and water in the tank after the test. The gravity and temperature of the oil may have to be measured as well.

Testing Wells

If the well is producing natural gas, that needs to be recorded. As gas breaks out at the separator, it has to be measured as it flows through the gas line using a gas meter. You can check previous measurements in the lease records to get an estimate of which meter orifice you should use. You’ll want to make sure the meter is operating properly; a few basic things like making sure the pens on the recorder aren’t stuck can save you trouble later on. Many meters these days are computerized; the design and functions on these can vary so it’s a good idea to review how the meter you’re using works.


Common Tests and Testing Information

Wells can be tested for a variety of reasons, but there’s a few basic tests that will need to be run regularly or which are common when first bringing a well into production. The specifics of the tests may vary depending on the operation and what specifically you’re testing for.


Potential Test

The potential test is used to find out how much a well can produce in one day. You should shut the well in and allow it to build to it’s maximum pressure before you run this test. The standard shut in time is about 24 hours, but can vary depending on the behavior of the well.

The potential test is most often done on new wells when their production rates and capability is being discovered. It’s also used with wells that have been worked over to discover what the new production rate will be like.


Oil-to-Gas Ratio Test

The name pretty much says it all. This test determines the ratio of oil and gas being produced from the well. This can be useful information for a number of reasons, but it’s particularly important as too high a percentage of gas can lead to a drop in reservoir pressure. That can have a wide impact on the production of any wells drawing from the same reservoir.

The oil-to-gas ratio test requires the well be shut in prior to the test to build pressure downhole.


Daily Test

The daily test is fairly straightforward, and is used to determine the normal daily production of a well. The daily test is run on the same day every month, and a record is kept to track this amount over the long term. As you’re trying to determine standard production, the well should be normalized before the test.


Productivity Test

This test covers the most area, with the goal of discovering how to produce the most oil while not reducing the well’s producing life. The idea is to operate the well in with few different ‘standard’ setups, and then measure the output of each. For productivity tests, you’ll usually need to normalize the well.


Recording Test Results

Most of the tests that are run on the lease will end up collecting a lot of information, which then has to be interpreted and analyzed. The amount of oil, water, and gas will generally be recorded, as those figures will be among the most helpful to look at. There are numerous oil and gas production allocation methods. And, to properly interpret those numbers, you’ll need to place the production in the context of the well and method of production.

Some basic lease information is usually required for all tests. A lot of it is standard requirements for paperwork, such as the name of the lease, the company that is operating it, the well being tested and the field where it’s located. The date of the test is helpful, as testing records are most useful when looking at the behavior of a well over time. The type of test, the condition of the well, and the length of the test are also important.

Details can help explain variances between the recorded and estimated production volumes, so many forms will require specific information such as the casing pressure before and after the test, the tubing pressure before and after, and more. Information specific to the lift method for a pumping well is also important. The stroke length and frequency can affect production so that needs to be recorded.

Other information that may end up being useful includes the state of the tank battery, and any extraordinary circumstances that may affect production, downtime, as well as any wells that are shut-in and the like. There are a lot of moving parts and these calculations can become complicated in a hurry (you can also check out the GreaseBook, which a simple cost-effective mobile app that can serve as the perfect oil and gas production allocation software…)

Send us your Well and Pumper info 📑

Your team sits back while our Petroleum Engineers turn key your build out, setting up all production facilities to precisely mirror what you’ve got going on in the field.

Day 1

Roll out Pumpers 👨🏻‍🦰👴🏻👨🏻👨🏾‍🦱👴🏽🧔🏼‍♂️📲

We train, instruct and hand hold your pumpers every step of the way. Typical time for a pumper to learn the app? 8 minutes.

Week 1

Immediate Results 🎯

  • Your production data in On Time: Because your pumper can enter production on ANY device (Android, Apple, tablet, PC, Mac, Desktop or Laptop) AND the app works offline, you’ve eliminated ANY excuse for you NOT to have your data. PS for better or worse, NOBODY leaves their home without their phone 😉
  • Your production data is Quality Controlled: Because the app checks your pumpers’ work, all your production data should now be QC’d.

Week 6

6% Lift in your Net Profit Margins Achieved or You Don’t Pay 💯💰📈

  • Your production data is in a Centralized Place: Because you have a simple system and everyone in the field knows how to work it, no one on the team ever has to wonder what’s really going on in the field.
  • The pulse and overall health of your company’s production is now known at all times
  • The status of any asset or pumper can be reviewed from any device
    • Because of this, you have now progressed to the point where you may want to set up Alerts around your production. To get you started (and get your creative juices flowing), we’ll implement two alerts on your behalf:
      • Comments
        • Get notified anytime a pumper leaves a comment without having to dig for it.
      • 7/14/30 Day Running Average
        • Get treatment to a well as soon as it shows signs of falling off.
    • However, the number and type of Alerts you can set up around your production are endless. A few common examples we see as having the biggest impact to your operations are:
  • Reduced Downtime
        • A well never sits idle for longer than it has to due to a pumper not calling it in.
  • Account for Every Drop of Oil
        • Each transfer of crude is meticulously tracked and every drop accounted for. No more skimming vacuum truck operators or purchasers pulling that extra inch of ‘velvet’ from your oil hauls.
  • Cap Ceiling Pressures on Injection and SWD wells
      • Injection wells are rated for certain pressures and blow outs are expensive. Get notified anytime an injector creeps above its maximum allowable pressure.
    • How many days since a Pumper last checked in? 👀
      • Do we trust our pumpers? Yes! Do we also want to verify they’re doing what they’re supposed to do? Oh yes!! Anytime a pumper goes AWOL for more than X days (doesn’t show up on site, doesn’t submit data) you know about it.

The bad news is you still have to work. The good news is you now have the power to put full oversight of both your pumpers and your production on automatic enabling you to focus on the activities in your company that will move the needle such as acquiring more wells, drilling and re-completions, or simply taking more time off 🏝️

Ask us anything


Not really. Simply share with us your Excel reports, paper gauge sheets, or the login to your existing legacy production software and we’ll take care of the rest. Our petroleum engineers turn-key your entire setup, we’ll reach out once we’re done. Bada bing.

You’re right. And, because no one leaves their house without their phone (and because our app works offline), we eliminate any excuse for your pumpers NOT to send you their data. See, we told you this would be easy.

In addition to both Android and Apple smartphones, the Greasebook also works on any tablet, laptop, or desktop.

While Greasebook has been implemented in many of the country’s largest publicly traded production companies operating thousands of wells, Greasebook is focused on serving the small and mid-sized independent US-based oil & gas operators.

Anywhere, anytime, on any device (phone, tablet, desktop or laptop).

The beauty of the app is once your pumpers start submitting their production via the Greasebook – anyone on your team can access production reports, graphs and well files from any device at any time.

It’s sorta like a centralized place from which everyone on your team can work, without all the calls, text messages and emails that would go on otherwise.

Absolutely. As your pumpers continue to add tickets, comments, pressures, well tests and any other relevant information, your investors will have guest access to as much (or as little) information as you’d like.

Of course, they’ll only see production info for the wells in which they participate.

Oil & gas companies who run Legacy oil and gas software systems expose themselves to major risks (and minor annoyances…)

The complexity of traditional oil & gas production systems is twofold:

  1. Software Problem: Legacy software systems are expensive, outdated, clunky and have extremely complex interfaces. In fact, because of all the support and manual interventions required, continuing to use outdated software can often be more costly than simply upgrading.
  2. People Problem: Legacy software systems take an enormous amount of time to familiarize oneself with. And, anytime an employee quits, retires, or is let go the amount of training required for new employees can be significantly higher than for newer, more user-friendly software.


This is a lose/lose. What’s more, given all the set-up fees, training fees, support fees and the like the projected ‘savings’ never materialize and now your forced to contend with fluctuating hydrocarbon prices AND a bloated monthly OPEX.

Talk about getting stuck in the muck!

With Greasebook, office users are 99% proficient with the platform in about 20 minutes.

Within 2 seconds – FROM YOUR SMARTPHONE – you’ll have your answer to any question regarding production, allocations, performance, well history files, commentary, run ticket reconciliation, Custom Reports, State reports, and more – all sliced and diced and customized at the Company, Operator, Battery, Well, State, County, Section, Township, Range, Acquisition, or even Supervisor level…

We’ve been at this for awhile. Greasebook was established in 2012 and now supports more than 400+ oil and gas operators (small ma & pops and publicly traded companies alike) across 20 States.

Today, Greasebook is now the fastest growing production software in the patch.👏

The Greasebook corporate outpost is proudly located in Oklahoma City, Oklahoma 🤠📍

The Greasebook helpdesk is staffed by Petroleum Engineers, Geologists, and Completions Experts Monday through Friday, 8AM to 5PM CST. 

We have a real-time chat through which most questions are answered in 2 minutes or less.

Naturally, some questions are more complex and you’ll want to speak to someone over the phone. In this case, we aim to complete all callbacks within two hours of scheduling.👌

Of course, your Dashboard and Reports are available to you 24/7.

We don’t blame them.

Pumpers have been burned by Legacy Production Systems in the past. 😵

However, given how much upside you stand to gain in the form of time savings and profit, DON’T let the tail wag the dog, folks!! 💸

Real talk: the average pumper takes about 8 minutes to learn Greasebook (and that goes for guys in their 80s still tending wells…)

Give us two days and we’ll make believers out of your entire pumping crew….

Still not convinced? Check out Greasebook’s “Pumper Wall of Love” by clicking here and let the pumpers tell you themselves 😘

Let us help you help yourself. Simply send us your existing production info, and we’ll assign one of our Petroleum Engineers to turn-key your entire setup for you.

We’ll build your wells, your tank straps, your users and anything else you require.

Finally, once everything has been reviewed by your team, we’ll roll out your pumpers and either train them for you or with you – whichever you prefer.

That’s not a question, but actually no.

The average pumper demands anywhere from $125 to $400 per month.

And depending on what you require, Greasebook is priced anywhere from $5-15 well/mo.

So, given how much more you’ll get out of your pumpers, how much we’ll streamline your operations, and how quickly we’ll get this all done for you, we’re actually kind of a bargain.

Our guarantee is two-pronged…

First, run the app for full 6 weeks in your operations. If you’re not completely satisfied YOU DON’T PAY.

Second, if for any reason you’d like your money back in first 30 days after paying simply let us know and it’s yours. 🤝

However, if you’re anything like our other 400+ operators you’ll be wondering why you didn’t do this 6 months ago…

We’re ready when you are. Take the quiz and schedule a call here – depending how many operators we have in front of you, there’s a chance we can get you up and running by the end of next week.
