Definition
Gas, in law, refers to a naturally occurring or manufactured aeriform substance treated as property, a commodity, or a regulated resource. Legal treatment varies significantly depending on whether the gas is natural (extracted from the earth as a hydrocarbon) or manufactured (produced industrially, as from coal), and whether the question at issue is property ownership, utility regulation, or environmental compliance. 1. Natural gas. A hydrocarbon substance occurring underground in gaseous form, often found in association with oil deposits. Natural gas presents distinctive property law problems because of its migratory nature: it moves through subsurface formations and does not remain fixed in place beneath any single parcel of land. Courts historically addressed this by analogizing gas to wild animals (ferae naturae), meaning ownership is not established by the gas lying beneath one's land but by actual capture and reduction to possession. Once produced and severed from the ground, gas becomes personal property subject to ordinary rules of sale, transfer, and contract. 2. Manufactured gas. Gas produced by industrial processes (historically, coal gas used for illumination and heating) and distributed through utility infrastructure. Companies supplying manufactured gas have long been treated as public utilities or quasi-public enterprises, subject to rate regulation, service obligations, and franchise requirements rather than the ordinary rules of private commerce. 3. Gas as a regulated commodity. Both natural and manufactured gas in commercial distribution are subject to extensive federal and state regulatory regimes governing pipeline safety, rates, environmental impact, and land use. For federal purposes, natural gas transported in interstate commerce falls primarily under the Natural Gas Act and the jurisdiction of the Federal Energy Regulatory Commission (FERC).
Common Language
Modern common usage (Wiktionary): A state of matter intermediate between liquid and plasma, capable of expanding to fill its container and subject to condensation into liquid under reduced temperature or increased pressure. Historical common usage (Webster's 1913): An aeriform, permanently elastic fluid, as oxygen or hydrogen, distinct from vapors that liquefy upon cooling; the term originally synonymous with "air" among early chemists. The legal meaning of "gas" is substantially narrower and more functional than the physical science definition. Law is not concerned with gas as a state of matter generally but with specific gaseous substances — primarily natural gas and historically manufactured illuminating gas — as objects of property, contract, and regulation. A lawyer asking about "gas rights" or a court construing a "gas lease" is operating in a domain entirely separate from the chemist's or physicist's use of the word.
Common Confusion
Natural gas and oil are frequently grouped together in legal instruments, statutes, and case law as "oil and gas," but they carry distinct property and regulatory consequences. The rule of capture applies to both, but unitization schemes, royalty calculations, and pipeline regulation treat them separately. Researchers should also distinguish natural gas (a mineral resource extracted from the earth) from gas utility service (a regulated delivery of manufactured or processed gas to consumers), as the applicable legal frameworks differ substantially. Early cases addressing "gas companies" almost always concern manufactured gas utilities, not natural gas producers — a distinction that matters acutely when reading nineteenth- and early twentieth-century authority.
Recognized Forms
/SUBTYPES Natural gas: Hydrocarbon gas extracted from geological formations, subject to the rule of capture, mineral leasing law, and federal pipeline regulation. Manufactured gas: Gas produced by industrial processes from coal or other feedstocks; historically the dominant form of utility gas before pipeline infrastructure made natural gas widely available. Casinghead gas (also: associated gas): Natural gas produced incidentally from an oil well, raising distinct royalty and severance questions under oil and gas leases. Coalbed methane: Natural gas extracted from coal seams; subject to ongoing disputes about whether it belongs to the coal estate or the gas estate when severed interests conflict.
Why It Matters in Research
The central research trap with "gas" is temporal. Cases and treatises before roughly the mid-twentieth century almost always address manufactured gas companies operating as local utilities. Researchers expecting natural gas doctrine and finding manufactured gas utility law — or vice versa — will reach incorrect conclusions about applicable rules. Always identify which type of gas is at issue before generalizing from historical authority. The ferae naturae analogy is foundational but contested. Bouvier notes that gas "may be classed by themselves, if the analogy be not too fanciful, as minerals ferae naturae," acknowledging even at the time that the analogy is imperfect. Modern cases and statutes have supplemented or displaced the common law rule of capture with unitization requirements, correlative rights doctrines, and regulatory production controls. Researchers relying on the rule of capture without checking the governing jurisdiction's statutory modifications will likely misstate current law. Jurisdictional variation in oil and gas law is substantial and often outcome-determinative. Texas, Oklahoma, Louisiana, Colorado, Wyoming, Pennsylvania, and West Virginia each have significant bodies of gas law that diverge on royalty calculation, implied covenants, pooling authority, and correlative rights. Federal law governs interstate pipeline transportation and rates (Natural Gas Act, FERC jurisdiction) but generally leaves subsurface ownership and leasing terms to state law, except on federal lands where the Mineral Leasing Act applies. For federal lands research, the distinction between onshore and offshore (Outer Continental Shelf) gas leasing is critical. The OCS Lands Act creates a separate federal leasing and regulatory regime for offshore gas distinct from the onshore Mineral Leasing Act framework. Researchers should also be alert to environmental law intersections. Natural gas pipeline and export terminal siting, hydraulic fracturing, methane emissions, and coalbed methane extraction each generate distinct bodies of administrative and environmental law that are not captured in traditional property or utility law sources.
Historical Dictionary Support
Bouvier's treatment of gas is notably bifurcated. The entry addresses gas companies as quasi-public enterprises operating under obligations distinct from ordinary businesses, reflecting the nineteenth-century context in which gas law developed around manufactured gas utilities holding municipal franchises. Bouvier then pivots to natural gas and introduces the ferae naturae analogy directly, acknowledging that natural gas requires "more careful consideration of the principles involved than of the mere decisions" — a candid signal that the law was unsettled and that mechanical application of prior mineral law decisions was insufficient. Bouvier's framing of gas companies as operating in a business that is "not an ordinary one" anticipates the public utility regulatory model that would later be codified. This passage remains useful for understanding why gas suppliers — unlike most property owners — have historically been subject to mandatory service obligations, rate oversight, and franchise controls. What Bouvier does not address is the modern natural gas industry at scale: interstate pipelines, federal rate regulation, liquefied natural gas (LNG), or the environmental dimensions of gas extraction and distribution. For these areas, Bouvier is useful only as background on the foundational property concepts; modern statutory and regulatory sources must carry the primary research load.
Jurisdictional Note
Gas law is among the most jurisdiction-specific fields in American property and energy law. The rule of capture remains the default common law rule but has been modified by correlative rights statutes and mandatory unitization laws in most major producing states. Federal jurisdiction over interstate gas pipelines is near-comprehensive under the Natural Gas Act, but subsurface ownership remains a matter of state law unless federal lands are involved.

In detinue, the defendant cannot have a scl. fa. to garnish a third person unless he confess the possession of the chattel or thing demanded; Brooke, Abr. And when the garnishee comes in, he cannot vary or depart from the allegation of the defendant in his prayer of garnishment. The plaint- iff does not declare de novo against the gar- nishee; but the garnishee, if he appears in due time, may have oyer of the original dec- laration to which he pleads. Where plaintiff in execution paid to the sheriff $1,000 as the value of the debtor's homestead interest, and the land was sold under execution, the money in the sheriff's hands was subject to garnishment at the instance of the other judgment creditors; 60 Ill. App. 65; money taken from a person without his consent by a sheriff acting as trespasser in so doing, and delivered by him to a third person claiming title thereto, is not subject of garnishment in the hands of the sheriff or to the third parties as the property of the person from whom it was taken; 40 Pac. Rep. (Wash.) 228. See Brooke, Abr.; Drake; Wade; Shinn, Attachment; ATTACHMENT.

An aeriform fluid, used for illu- minating purposes and for fuel. From a legal point of view it is to be con- sidered with respect to the companies by which it is usually furnished, their status and obligations as affected by the nature of the business; and also whether the gas furnished by them is manufactured or nat- ural. Nature of the business. The business is not an ordinary one in which any person may engage as of common right, but a franchise of a public nature which, in the absence of constitutional restriction, may be granted by the legislature; 115 U. S. 650; id. 683; 33 Fed. Rep. 659; 84 Ky. 166. A grant of the right to lay pipes is valid, but it is a franchise to be strictly construed, and is void if the conditions are not com- plied with, pursuant to the legislative dec- laration in the grant; id. 46. Such a com- pany cannot sell, lease, or assign its corpoо- rate privileges without consent of the legis- lature; 85 Me. 532. They are not, however, always treated as strictly public corporations, but in some cases such a company is said to be simply "a private manufacturing corporation which furnishes gas to individuals as agreed. This of itself does not make it a public corporation;" 63 N. Y. 326. A com- pany furnishing gas to a municipality un- der contract is not performing such public service as to exempt it from ordinary taxa- tion; 20 S. W. Rep. (Ky.) 434. A gas company having power to manu- facture and sell gas has an implied power to make all contracts necessary to that end; 86 Mo. 495. For example, in the practice of Pennsyl- vania, when a writ of attachment issues against a debtor, in order to secure to the plaintiff a claim due by a third person to such debtor, it is served on such third per- son, which notice or service is a garnish-acter, such gas has been termed "a min- Natural Gas.

eral with peculiar attributes which require the application of precedents arising out of ordinary mineral rights, with more careful consideration of the principles involved than of the mere decisions. Water and oil, and still more strongly, gas, may be classed by themselves, if the analogy be not too fanciful, as minerals feræ naturæ. In common with animals, and unlike other minerals, they have the power and the tendency to escape without the volition of the owner. Their fugitive and wander- ing existence within the limits of a particu- lar tract is uncertain;' (per Agnew, C. J. in 80 Pa. 147). They belong to the owner of the land, and are part of it, so long as they are on or in it, and are subject to his control; but when they escape, and go into other land, or come under another's control, the title of the former owner is gone. Possession of the land, therefore, is not necessarily possession of the gas. If an adjoining, or even a distant, owner, drills his own land, and taps your gas, so that it comes into his well and under his control, it is no longer yours, but his." Per Mitchell, J., in 130 Pa. 235. Under a lease of land for the sole purpose of drilling and operating for oil and gas, the lessee's right in the surface of the land is in the nature of an easement of entry and ex- amination, with a right of possession where the particular place of operation is selected, and the easement of ingress and egress, transportation and storage; id. Whether the words "other valuable volatile substance" in a lease when they were used with petroleum, rock, or carbon oil, will include gas is a question for a jury, as the words have no settled meaning; 11 Pa. 31. The words oil and gas in a lease have been held not synonymous; 6 Atl. Rep. (Pa.) 74; it is a fuel; 114 Ind. 338; but it has been held that a company incor- porated for supplying heat cannot also fur- nish natural gas; 108 Pa. 126. Natural gas is as much an article of com- merce as any other product of the earth; 120 Ind. 575; and a state statute making it unlawful for any person to conduct nat- ural gas out of the state violates the pro- visions of the federal constitution vesting in congress the regulation of interstate com- merce; id.; 118 Pa. 468. The business of transporting and fur- nishing natural gas is a public use, and the right of eminent domain may be constitu- tionally granted to companies engaged in it; 5 Cent. Rep. (Pa.) 564; the business is transportation of freight; 118 Pa. 408. Because of the public nature of the busi- ness taxation may be authorized for sup- plying it to municipal corporations; 39 Fed. Rep. 51; and any unreasonable restraint upor the business is against public policy; 130 111. 268. It was held that under the Pennsylvania general incorporation act of 1874, under which companies for the manu- facture and supply of gas were formed, natural gas companies could not be incor- porated; 108 Pa. 111; 111 id. 35. Conse- quently a general law was passed providing for such companies under which, when lawfully incorporated, may they exercise the right of eminent domain and the grant of the power is constitutional: 120 Ind. 581; 63 Barb. 437; 115 Pa. 4; 160 id. 367; and the use of city streets for that purpose imposes no additional servitude; id. In Pennsylvania, the courts of common pleas may hear and determine controversies be- tween natural gas companies and munici- palities as to the manner of laying their pipes; 115 Pa. 4. A right to take natural gas from land under the Pennsylvania act of Apr. 7, 1870, P. L. 58, is not land held in fee, subject to be sold under a special fi. fa, against an in- solvent corporation; 162 Pa. 78. The lessee for oil and gas, having drilled a well and tapped the gas-bearing strata (the only one in the land), has both the possession of the gas and the right to it, and the owner will be enjoined from drilling; 130 Pa. 235. A lessee for oil only who took from the well both oil and gas was held not accountable to the lessee for the gas, which is, like air and water, the subject only of qualified property by occupancy; 28 W. Va. 210. From the nature of the gas, a lease of well- rights is necessarily exclusive so far as con- cerns the leased premises themselves; id.; 130 Pa. 235. A person who has a natural gas well on his premises has the right to explode nitro-glycerine therein for the purpose of increasing the flow, although such explo- sion may have the effect to draw gas from the land of another; '181 Ind. 599. See also as to natural gas, 30 Cent. L. J. 497; 29 Am. L. Reg. 93, 102; 34 Am. & Eng. Corp. Cas. 46-8. The rights and liabilities of gas com- panies are, in the main, the same, whether they are engaged in the business of supply- ing artificial or natural gas. Municipal lighting. The business is usually carried on by companies acting either under a legislative or municipal fran- chise or contract, or directly by the munic- ipality under express legislative authority or implied power.

An aëriform fluid; -- a term used at first by chemists as synonymous with air, but since restricted to fluids supposed to be permanently elastic, as oxygen, hydrogen, etc., in distinction from vapors, as steam, which become liquid on a reduction of temperature. In present usage, since all of the supposed permanent gases have been liquified by cold and pressure, the term has resumed nearly its original signification, and is applied to any substance in the elastic or aëriform state. A complex mixture of gases, of which the most important constituents are marsh gas, olefiant gas, and hydrogen, artificially produced by the destructive distillation of gas coal, or sometimes of peat, wood, oil, resin, etc. It gives a brilliant light when burned, and is the common gas used for illuminating purposes. Laughing gas. Any irrespirable aëriform fluid.
