“Frac sand,” commonly a particular kind of crystalline silica sand used to hold open fractures created in reservoir rock that allow easier capture of oil and gas, presents an opportunity for clarification of the difference between the two estates recognized by Texas law: mineral and surface estates. Mineral reservations in Texas are often accomplished by specifying the mineral estate as consisting of “oil, gas and other minerals.” The pertinent question is thus whether sand used in fracking falls into the category of “other minerals.”
In Texas, minerals include “all substances within the ordinary and natural meaning of that word, whether [or not] their presence or value is known at the time of severance,” with the exception of “certain substances” that “belong to the surface estate as a matter of law.” Sand is one such substance that the Texas Supreme Court has identified to be part of the surface estate as a matter of law.
But the reasoning behind this definition of minerals provides potential for certain kinds of sand to be exceptional to the rule. The Texas Supreme Court noted that the definition of mineral should focus on the general intent of the parties, and that this general intent is “presumed” to include an intent to “convey all valuable substances,” regardless of whether the parties had pre-existing knowledge of the presence of the substances in the grant.
In part because frac sand is so important to the fracking process, the estimated value of industrial sand has significantly increased; experts estimated prices to have doubled on average between the second half of 2016 and the first part of 2017. As a result of increased demand, some countries have banned or restricted the export or mining of many kinds of sand, resulting in the development of some black markets and money-making opportunities for organized crime. While it is possible to crush rocks into artificial sand to meet demand, the quality of this sand is not as high and processing costs make artificial sand more expensive. In Texas, sand mining has recently “exploded,” including mining operations in the Permian Basin and at locations near San Antonio and between Austin and Dallas.
The contemporary rise in the value of and demand for industrial sand may warrant a revisiting of which substances are as a matter of law part of the mineral estate. If judicial focus is trained on the intent of the parties at the time of the grant, it indeed makes little sense to interpret a grant of minerals to include the “top soil, which, under conditions arising subsequently to the grant, should become commercially valuable.” On the other hand, a grant of minerals for lands “valuable solely or chiefly” because of the presence of a certain kind of substance may fairly be construed to include such substance in the definition of mineral.
Within these two extremes, the test might be whether the substance “at the time of the grant” was sufficiently “exceptional in use or value.” Exceptional use or value logically plays a critical part in the whether the parties considered such substance as ordinarily and naturally part of the valuable mineral estate at the time of the grant. While one might argue that the frac sand cannot be exceptional in use or value because its demand is solely derivative from demand for other minerals, such a requirement is unworkable where the intent of the parties, or market forces more generally, require otherwise, particularly where such sand is also used in other end-user products.
The increased value of crystalline silica and other industrial sands may thus warrant an exception from general Texas precedent. But Texas law imbues some “magic” in the word mineral that allow drafters to rely on its “talismanic power to create certainty in their instruments.” The Court may thus be justifiably “loathe” to change the definition of mineral as relied upon by the contracting parties. Ironically, such reluctance may have unnaturally frozen the ordinary and natural meaning of minerals in time.
