Have a Texas Oil and Gas Lawyer Make Sure Your Royalties Are Correct
Part of what I do for clients as a Texas oil and gas attorney is to calculate oil and gas royalties so that they can be sure they are being paid correctly. I thought it might be useful to you to explain how an ownership percentage and royalty are calculated.
1. First, we take your percentage of mineral ownership in the land in question, and we multiply that by the number of surface acres in your entire tract. This result is that your net mineral acres. For example, if two relatives together own a one-half interest in a forty acre tract, or ½ times 40, they have twenty net mineral acres.
2. Secondly, if the land is located in a pooling unit, (sometimes also called a pro-ration unit), we multiple the total number of acres in the tract by a pro-ration fraction. The reason for this is that each royalty owner in a pooling unit is only entitled to their proportionate share of the oil or gas produced by the entire pooling unit. A pooling unit is an area around a well that is set by the Texas Railroad Commission, and is intended to approximate the area drained by a producing well. Pooling units can range in size from 80 to 640 acres or more. For example, for a forty acre tract that is located in a 320 acre pooling unit, that forty acre tract is entitled to 40/320, or 0.12500, of the minerals (whether oil or gas or both) produced by that 320 acre unit.
3. Third, we multiply that result by the royalty fraction in the oil and gas lease you signed.
4. Finally, we divide that result by the number of current owners to determine what portion of the total production from the pooling unit each owner is entitled to.
By way of example, let’s say you and a relative own 20 net mineral acres in a 40 acre tract. Let’s also say that the pooling unit is 320 acres. This fraction in our example would be 40/320. Next we multiply that result by the royalty fraction in the oil and gas lease that was signed, which in our example is 1/6. Finally, we divide that result by the number of owners, which in our example is two.
Here is the calculation for our example in numeric form:
First, I convert the fractions to decimals so they are easier to multiply:
20/40 = 0.5
40/320 = 0.12500
1/6 = 0.166666
1/2 = 0.5
Next, I multiply out the calculation:
0.5 X 0.12500 X 0.166666 X .5 = 0.005206
The result of this calculation is that for every dollar of gas sold from the well, you and your sister in our example would each get 0.005206 of that dollar. This does not seem like much, but a good gas well can produce millions of BTU's of gas, and so the royalty payments can be substantial.
Oil and gas companies can and do make mistakes in calculating a mineral owner's royalties. If you think your royalties are not being calculated correctly, give me a call.
Next, I research the status of your relative’s ownership of the real property that may be subject to an oil and gas lease or leases. Even if you already have a legal description of the property, it is essential to make sure that your relative has not, unknown to you, conveyed or transferred the property in question to a third party, or perhaps lost the property due to delinquent taxes. If we proceed without the precise legal description of each parcel of real property, or if the legal description is inaccurate or incomplete, or if your relative has sold or lost the property or the mineral interest, the time and expense involved in further work will be wasted. 
My flight instructor used to have a rule he would use when I was doing something bad while I had the plane and he wanted me to stop it immediately because I was getting ready to kill both of us. He called it "Rule 13" and it meant "Whatever you are doing, stop it!" To all of you folks out there who sign a lease without reading it, or who read a lease and don't understand it or who don't understand the legal ramifications of what you are signing, I would say: "Rule 13...Don't do that!". In most cases, I can negotiate with the oil company to make changes that will make the lease much more fair and much more favorable to you. In almost every lease I have negotiated, the oil company has accepted most, if not all, of these changes. For most leases, I charge a very modest set fee. Many of my clients find that the increase in their bonus or royalty check more than pays for my legal service. An oil and gas lease is a serious legal contract that is going to control your land, in many cases, for many years to come. So please seek legal advice before you sign that lease!
One of the frustrating and, in my opinion, inequitable, aspects of the new tax is that companies that produce tangible goods are able to deduct the cost of making those goods, under the
