Preparing and Selling Oil & Gas Production

The sales process is an important one, and a fair bit of time should be devoted to preparing for it. Once you’ve pumped, separated, and treated a load of oil, it should be made ready for testing and assessment by the purchasing gauger. If the gauger isn’t satisfied, the load can be refused. That’s frustrating for you, leaving you with a full stock tank production backing up. The gauger is unhappy because he has to make sure he has a backup load to pick up, and everyone is making less money. Properly preparing the oil may be time consuming, but it’s a necessary part of the process.

Selling Oil


Preparing And Selling Oil

There’s just a few basic requirements the oil needs to meet before it can be sold. If you’re selling by truck or otherwise selling one tank monthly, you’ll need to make sure you have a full load ready to go. In a tank ready to be sold, the total percentage of water, sediment, and other contaminants meets the purchaser’s requirements; usually that percentage is less than 1%. And the amount of bottoms, the emulsion that forms from the heavier elements of the purchased fluid, must also meet the requirements set out by the purchaser. Normally, the level of bottoms should be at least 4 inches below the sales outlet.

The most common methods for selling oil are selling through an automatic LACT Unit and selling by truck transport. Selling by truck is a more complicated process, as it requires you to have a full load of treated and separated oil ready to go by a specific date. It also requires communication with a gauger and transport driver. A LACT Unit allows you to sell oil as soon as it’s ready to go, without waiting. However, LACT Units aren’t available in every situation, and truck transport may be your only option.

There’s another requirement regarding the oil’s temperature, but which only rarely applies. The oil’s temperature can affect its volume, with higher temperature oil taking up more space. For that reason, a corrective factor will be applied to the volume the purchasing gauger measures when he picks up a load, and which is covered a bit more below. In some cases, however, the oil will have been heated to the point that a purchasing company would not accept it. This is most often the case when the oil has been heated to solve treating problems that may arise when a thicker oil with lots of paraffin is being produced from the well.

In addition to taking up a greater volume, oil heated to a higher temperature can be dangerous to handle and pump, as it’s much more likely to ignite. You may want to sell the oil right after it’s been heated, as the paraffin and heavier elements of the oil will flow more easily, and so they’ll flow out of the tank when the oil is sold. That can help keep the tank bottom clean. But many transportation companies won’t accept oil that’s over 100 degrees Fahrenheit.


Selling Using A LACT Unit

A LACT Unit (standing for Lease Automatic Custody Transfer) is an automatic method of selling oil directly into a pipeline. The unit is attached directly to the stock tank, which essentially becomes a surge tank. The LACT unit is able to gauge when the oil in the tank is ready to be sold, and also able to monitor the level of oil in the tank. As oil of sufficient quality is produced into the tank, the LACT Unit activates and sells oil into the pipeline. When the level of oil drops, the unit automatically shuts off. It will also stuff off if the quality of the oil falls below the set standards.

Selling Oil

Figure 1. An example of a LACT Unit. To left it connects to the tank, and to the right it feeds into the pipeline. You can see the control panel behind the unit.

Selling Oil

Figure 2. A second LACT Unit. You can see two lines leading to a prover loop from the front of the unit.

The unit is made up of a few different components. The liquid transfer pump maintains about 30 psi to keep gas from separating further from the oil, and so that a positive displacement meter can accurately measure the flow. A meter of this sort measures flow by using a mechanical flow meter of some sort, like a gear, and so may need more pressure to operate accurately. A backpressure valve before the pipeline helps keep that pressure up.

As meters age, they may lose accuracy, showing a higher volume than was actually sold. Meters have to be tested regularly, and a corrective factor may have to be applied to the meter readings. This factor, usually close to 1.000, corrects for the error measured in the meter. Another safeguard to prevent that sort of problem is the prover loop, which also verifies the reading from the meter.

The LACT unit keeps track of the sediment and water percentage in the oil as it sells it to the pipeline. If the oil doesn’t meet the requirements, the unit will automatically send it back through the tank battery.


Transporting By Truck

Selling using a LACT Unit is great, but it’s often not a method that’s available to everyone. When you’re not able to sell directly to a pipeline, selling by truck may be your only option. This is generally a more complicated process that may require some more work on your part. A gauger representing the purchaser will come to assess and test the oil. Based on his assessment, the purchase price may go up or down a bit, or he may refuse a load of oil altogether. A sales system for pumping oil into the transport truck also has to be built and maintained.

Selling Oil

Figure 3. A tanker truck for transporting oil.

Selling Oil

Figure 4. A note jar on an oil lease.

Different areas and gaugers will have a different process for getting in touch and scheduling a pickup. Most often, you’ll communicate with the gauger by cellphone or radio. There are some places where there is some sort of visual signal to the gauger, who drives around on a regular route. There should be some way of leaving paperwork on the lease, either a mailbox or a note jar.

The purchasing company will usually require you to have a full load of 210 barrels, or close to it. There’s two primary reasons for that. The first is cost. The expense of driving and pumping a full load is almost the same as that for a half load, so they make a bigger profit with a full load. Perhaps more importantly, driving a full load is actually safer. Oil is lighter than water, but even half a tanker load is still quite heavy. If the oil begins to move around the tank, it can make the truck difficult to control or even tip it over. With a full tank, there’s less room for the oil to move and so less risk. There are baffles that divide the tank up so that the risk is lessened, but a full load is still the safest option.

With that said, if there’s a problem with a tank or other emergency, the purchaser will often make an exception and accept less than a full load.

It may be required that you are present when the gauger tests a tank of oil. Even if it’s not required, it’s usually a good idea. Gaugers tend to be more careful, and it helps the process run a little smoother. Gauging the tank yourself before the gauger arrives is always wise, though the gauging volume will vary depending on the temperature. Consistent readings from day to day are unlikely.

There will be occasions when a tank is rejected by the gauger. That’s not ideal, and should be a fairly rare event. When the gauger does reject a tank, a notice is left for the pumper, and a copy most likely sent to the purchasing company. The notice will list some useful information, such as the date, the name of the pumping company, the lease where the tank was located, and the specific tank that was rejected. It will also list why the tank was rejected, which is probably the most useful piece of information.

The purchasing company will number the tanks in the battery, normally starting with lower numbers to the left, and counting up sequentially to higher numbers on the right. Out of sequence tank numbers usually indicates the tank has been replaced or restrapped.

Selling Oil

Figure 5. An example of a run ticket.

A run ticket is a proof of sale, and is usually filled out for each run by the truck driver. In Figure 5 you can see an example. It lists a variety of information, such as the capacity of the tank, the depth measured before and after pumping, and the level of bottoms. It also gives the gravity and temperature read for the tank load, which will be used to correct the sales price. Other information is more relevant to the purchasing company, such as how long the driver took to make the trip, when he left, when he returned, and so forth. A carefully read run ticket can reveal a lot of information about the well. For example, on this ticket there is a wide difference between the old and new seal numbers. That implies the well rarely has a full load, and therefore likely only produces marginal amounts.

You’ll receive a check for the sold oil the following month. The purchasing company will usually take care of the split between operator and mineral rights holder.


Seals And Sealing Lines

When selling by truck, sales lines are usually sealed between pickups. The seals have numbers that are recorded, and are usually only removed and replaced by the gauger. If you do have to remove a seal placed by the purchasing company, you should keep it and record the seal number. You’ll most likely be required to supply the seal as well as an explanation for why it was removed.

Selling Oil

Figure 6. Examples of the two types of seals.

There are two general types of seals in use. The first is a flat metal strap that locks down to itself. This style has to be pushed through a dart to work correctly. The other type of seal is a ware and lead ball. The wire is used to seal the valve, and then the lead ball is crimped shut onto the wire. In both cases, the seal has to be removed for the valve to be opened. The seal will be removed by the truck driver and then replaced once the oil is loaded.

Seals will have some information on them, like an identifying number and the name of the purchasing company. For selling by truck, the driver usually handles removing and replacing seals. When selling by pipeline, you may need to have a representative from the purchasing company present.

How CAN we guarantee you a 6% lift in profit margin in 6 weeks*?

*PLEASE NOTE: 6% is the AVERAGE result of producers who implement the app into their operations..... which means a full HALF of our clients do better 🤑


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.
