2. Soil liquefaction - Wikipedia

   en.wikipedia.org/wiki/Soil_liquefaction

   This is a soil test-based definition, usually performed via cyclic triaxial, cyclic direct simple shear, or cyclic torsional shear type apparatus. These tests are performed to determine a soil's resistance to liquefaction by observing the number of cycles of loading at a particular shear stress amplitude required to induce 'fails'.

3. Percolation test - Wikipedia

   en.wikipedia.org/wiki/Percolation_test

   Percolation test. A percolation test (colloquially called a perc test) is a test to determine the water absorption rate of soil (that is, its capacity for percolation) in preparation for the building of a septic drain field (leach field) or infiltration basin. [1] The results of a percolation test are required to design a septic system properly.

4. Separator (oil production) - Wikipedia

   en.wikipedia.org/wiki/Separator_(oil_production)

   Separator (oil production) The term separator in oilfield terminology designates a pressure vessel used for separating well fluids produced from oil and gas wells into gaseous and liquid components. A separator for petroleum production is a large vessel designed to separate production fluids into their constituent components of oil, gas and water.

5. Geotechnical investigation - Wikipedia

   en.wikipedia.org/wiki/Geotechnical_investigation

   A soil sample recovered from a test boring using a split spoon sampler. Borings come in two main varieties: large diameter and small diameter. Large-diameter borings are rarely used because of safety concerns and expense but are sometimes used to allow a geologist or an engineer to visually and manually examine the soil and rock stratigraphy in-situ.

6. Basic sediment and water - Wikipedia

   en.wikipedia.org/wiki/Basic_sediment_and_water

   Basic sediment and water. Basic sediment and water (BS&W) is both a technical specification of certain impurities in crude oil and the method for measuring it. When extracted from an oil reservoir, the crude oil will contain some amount of water and suspended solids from the reservoir formation. The particulate matter is known as sediment or mud.

7. Well test (oil and gas) - Wikipedia

   en.wikipedia.org/wiki/Well_test_(oil_and_gas)

   Well test (oil and gas) In the petroleum industry, a well test is the execution of a set of planned data acquisition activities. The acquired data is analyzed to broaden the knowledge and increase the understanding of the hydrocarbon properties therein and characteristics of the underground reservoir where the hydrocarbons are trapped.

8. Oil well - Wikipedia

   en.wikipedia.org/wiki/Oil_well

   An oil well is a drillhole boring in Earth that is designed to bring petroleum oil hydrocarbons to the surface. Usually some natural gas is released as associated petroleum gas along with the oil. A well that is designed to produce only gas may be termed a gas well. Wells are created by drilling down into an oil or gas reserve and if necessary ...

9. Tank leak detection - Wikipedia

   en.wikipedia.org/wiki/Tank_leak_detection

   Tank leak detection. Tank leak detection is implemented to alert the operator to a suspected release from any part of a storage tank system, what enables to prevent from soil contamination and loss of product. In many countries regulated UST are required to have an approved leak detection method so that leaks are discovered quickly and the ...
