Relief well - A well drilled in a high-pressure formation to control a blowout.
Reserve - That portion of the identified resource from which a usable mineral and energy commodity can be economically and legally extracted at the time of determination.
Reserve (pool) - A porous and permeable underground formation of producible oil and/or natural gas, confined by impermeable rock or water barriers, and characterized by a single natural pressure system.
Reservoir - A porous, permeable sedimentary rock formation containing quantities of oil and/or gas enclosed or surrounded by layers of less permeable or impervious rock. Also called a "horizon."
Reservoir pressure - The pressure at the face of the producing formation when the well is shut-in. It equals the shut in pressure at the wellhead plus the weight of the column of oil in the hole.

Rotary drilling - A method of well-drilling that employs a rotating bit and drilling mud to cut through rock formations.
Roughnecks - Members of the drilling crew.

Roustabout - A semi-skilled hand who looks after producing wells and production facilities.
Royalty - A payment to a landowner or mineral rights owner by a leaseholder on each unit of resources produced.
Royalty Funds - Generally speaking, a royalty fund is when royalty interests are being bought, sold and held by the funds sponsors. In nearly all leasing situations, once a lease has been developed, it provides a revenue stream. A portion of the revenue stream is set aside for royalty which generally amounts to 12.5% and overriding royalty &/or carried working interest of 2-5%. In a royalty fund the objective of the fund is to generate it's revenue from royalties that are held from different producing fields throughout the country. The main feature to owning a percentage of a royalty fund is that with an oil royalty the royalty owner (or interest owner) pays no percentage of operating or developmental costs associated with the production of the oil or gas. Royalty programs generally offer a low risk factor along with a relatively low return. However, their main feature is that these types of programs last for many many years.

Sample log - A record of rock cuttings made as a well is being drilled. A record is then kept that shows the characteristics of the various strata drilled through.
Sandstone - Rock composed mainly of sand-sized particles or fragments of the mineral quartz.
Saturation - 1. The extent to which the pore space in a formation contains hydrocarbons or connate water. 2. The extent to which gas is dissolved in the liquid hydrocarbons in a formation.

Sedimentary rock -Rock formed by the deposition of sediment, usually in a marine environment.
Seismic exploration - A method of prospecting for oil or gas by sending shock waves into the earth. Different rocks transmit, reflect, or refract sound waves at different speeds, so when vibrations at the surface send sound waves into the earth in all directions, they reflect to the surface at a distance and angle from the sound source that indicates the depth of the interface. These reflections are recorded and analyzed to map underground formations.
Seismograph A device that records natural or manmade vibrations from the earth. Geologists read what it has recorded to evaluate the oil potential of underground formations.
Selling Expenses Expenses incurred in marketing interests in securities and commonly paid out of the investor's capital investment.
Separator A pressure vessel used to separate well fluids into gases and liquids.
Service well A well drilled in a known oil or natural gas field to inject liquids that enhance recovery or dispose of salt water.
Set casing To cement casing in the well hole, usually in preparation for producing a commercial well.
Severance The owner of all rights to a tract of land can sever the rights to his land (vertically or horizontally). In horizontal severance, for example, if he chooses to sell all or part of the mineral rights, two distinct estates are created: the surface rights to the tract of land and the mineral rights to the same tract. The two estates may change hands independently of each other.
Severance tax Tax paid to the state government by producers of oil or gas in the state.
Shale A type of rock composed of common clay or mud.
Shale oil The substance produced from the treatment of kerogen, that hydrocarbon found in some shales, which is difficult and costly to extract. About 34 gallons of shale oil can be extracted from one ton of ore.
Shale shaker A vibrating screen or sieve that strains cuttings out of the mud before the mud is pumped back down into the borehole.
Sharing arrangement An arrangement whereby a party contributes to the acquisition, or exploration and development, of an oil and gas property, and receives as compensation, a fractional interest in that property.
Shoestring sands Narrow strands of saturated formation that have retained the shape of the stream bed that formed them. In the United States, such a formation is located in Kansas.
Shoot a well A technique that stimulates production of a tight formation by setting off charges downhole that crack open the formation. The early wells were shot with nitroglycerin; then dynamite was used. The nitro man has been replaced today by acidizers and frac trucks.
Show - An indication of oil or gas observed and recorded during the drilling of a well.
Shut-down well/shut-in well - A well is shut down when initial drilling ceases for one reason or another. A well is shut in when the wellhead valves are closed, shutting off production, often while waiting for transportation or for the market to improve.

Stocktank barrel - A barrel of oil at the earth's surface.
Stratigraphic test - A hole drilled to gather information about rock strata in an area.

Swab -A hollow rubber cylinder with a flap (check valve) on the bottom surface. It is lowered below the fluid level in the well. This opens the check valve allowing fluid into the cylinder. The check valve flap closes as the swab is pulled back up, lifting oil to the surface.
Sweet crude - Crude oil with low sulfur content which is less corrosive, burns cleaner, and requires less processing to yield valuable products.
Syncline - A downfold in stratified rock that looks like an upright bowl. Unfavorable to the accumulation of oil and gas.
