- Company Profile:
Crude oil containing low levels of sulfur compounds, especially hydrogen sulfide (H<sub>2</sub>S). The facilities and equipment to handle sweet crude are significantly simpler than those required for other potentially corrosive types of crude oil.
Industry:Oil & gas
Crude oil direct from the wellbore, before it is treated in a gas separation plant. It usually contains nonhydrocarbon contaminants.
Industry:Oil & gas
Corrosion associated with the presence of hydrogen sulfide (H<sub>2</sub>S). Sour corrosion occurs in several forms of hydrogen embrittlement that cause materials to fail at stress levels below their normal yield strength. This can be problematic in applications where higher strength steels are used. Selection of materials resistant to the effects of H<sub>2</sub>S is the primary means of controlling sour corrosion.
Industry:Oil & gas
Corrosion (oxidization) resulting from exposure of susceptible materials to oxygen and moisture. Atmospheric corrosion is generally associated with surface storage conditions, or with upper wellbore annuli that may not be fluid-filled.
Industry:Oil & gas
Contaminated with sulfur or sulfur compounds, especially hydrogen sulfide. Crude oil and gas that are sour typically have an odor of rotten eggs if the concentration of sulfur is low. At high concentrations, sulfur is odorless and deadly.
Industry:Oil & gas
Contaminants such as hydrogen sulfide (H<sub>2</sub>S), carbon dioxide (CO<sub>2</sub>), nitrogen (N<sub>2</sub>), and water, which are commonly associated with oil and gas production.
Industry:Oil & gas
Consideration paid to the lessor by a lessee to extend the terms of an oil and gas lease in the absence of operations and/or production that is contractually required to hold the lease. This consideration is usually required to be paid on or before the anniversary date of the oil and gas lease during its primary term, and typically extends the lease for an additional year. Nonpayment of the delay rental in the absence of production or commencement of operations will result in abandonment of the lease after its primary term has expired.
Industry:Oil & gas
Components of natural gas that are liquid at surface in field facilities or in gas-processing plants. Natural gas liquids can be classified according to their vapor pressures as low (condensate), intermediate (natural gasoline) and high (liquefied petroleum gas) vapor pressure. <br><br>Natural gas liquids include propane, butane, pentane, hexane and heptane, but not methane and ethane, since these hydrocarbons need refrigeration to be liquefied. The term is commonly abbreviated as NGL.
Industry:Oil & gas
Completion of or flow from less than the entire producing interval. This situation causes a near-well flow constriction that results in a positive skin effect in a well-test analysis.
Industry:Oil & gas
Colloquial expression for a target location or area within a play or a reservoir that represents the best production or potential production. Geoscientists and engineers attempt to map sweet spots enable wellbores to be placed in the most productive areas of the reservoir. Sweet spots in shale reservoirs may be defined by source-rock richness or thickness, by natural fractures, or by other factors, using geological data such as core analysis, well log data, or seismic data. <br>
