11Well kill — A well kill refers to the operation of placing a column of heavy fluid into a well bore in order to prevent the flow of reservoir fluids without the need for pressure control equipment at the surface. It works on the principle that the weight of… …
12Drilling rig (petroleum) — The equipment associated with a rig is to some extent dependent on the type of rig but typically includes at least some of the following items: #Mud tank #Shale shakers #Suction line (mud pump) #Mud pump #Motor or power source #Vibrating hose… …
13Well intervention — A well intervention, or well work , is any operation carried out on a oil or gas well during , or at the end of its productive life, that alters the state of the well and or well geometry, provides well diagnostics or manages the production of… …
14gas-cut mud — /ˈgæs kʌt mʌd/ (say gas kut mud) noun (in oil well drilling) mud, introduced into the hole, which has been lowered in effective density by natural gas rising from the strata traversed …
15Drilling fluid invasion — is a process that occurs in a well being drilled with higher wellbore pressure than formation pressure. The liquid component of the drilling fluid (known as the mud filtrate) continues to invade the porous and permeable formation until the solids …
16Gas hydrates — are solid crystalline compounds formed under certain thermo baric conditions from water (water solution, ice, water steams) and low molecular weight gases. Externally, they look like ice or snow. Under moderate pressure natural gas hydrates exist …
17drilling machinery — equipment used to drill holes in the ground for such activities as prospecting, well sinking (petroleum, natural gas, water, and salt), and scientific explorations. Drilling holes in rock to receive blasting charges is an operation in… …
18drilling mud — noun a mixture of clays and chemicals and water; pumped down the drill pipe to lubricate and cool the drilling bit and to flush out the cuttings and to strengthen the sides of the hole • Syn: ↑drilling fluid • Hypernyms: ↑lubricant, ↑lubricator,… …
19drilling mud — a water based or oil based suspension of clays pumped into an oil well during drilling in order to seal off porous rock layers, equalize the pressure, cool the bit, and flush out the cuttings. Also called drilling fluid. * * * ▪ excavation… …
20Oil well — The pumpjack, such as this one located south of Midland, Texas, is a common sight in West Texas. An oil well is a general term for any boring through the earth s surface that is designed to find and acquire petroleum oil hydrocarbons. Usually… …
