What is reservoir drive mechanism?
A reservoir drive mechanism is that mechanism in which oil is derived by water or gas or both water and gas drive the oil from the well. Is called reservoir drive mechanism.
At the top of an oil reservoir is a layer of?
oil, gas, rock, water
What is oil leg reservoir?
Thin oil zone below a gas cap
What is mechanical drive?
A reservoir drive mechanism is that mechanism in which oil is derived by water or gas or both water and gas drive the oil from the well. Is called reservoir drive mechanism.
Which substance is generally encountered first when an oil and gas reservoir is drilled?
natural gas
What is the definition of oil rim?
In petroleum engineering, an oil rim field is an oil field with a relatively thin oil zone below a gas cap. At the edges of the reservoir there will ususally be an area where the top of the reservoir is below the gas/oil contact, thus forming a "rim" containing only oil, with no overlying gas.
9- If a homogeneous reservoir contains a gas cap at initial condition the fluid at the gas-oil contact should be?
Oil
Do you mix oil into the gas for a 1979 Yamaha qt50 50cc moped?
In most cases you should not mix oil into the gas of your 1979 Yamaha 50 cc moped. This type of moped had its own oil reservoir. If it is not marked on the gas You do not need to oil with the gas.
What is a infill well?
An infill well is a type of oil or gas well drilled in between existing wells within the same reservoir to maximize production from the area. By extracting oil or gas from areas that were not reached by the original wells, infill wells can help increase overall recovery rates from a reservoir.
What is oil reservoir drive mechanisme?
The process in which reservoir fluids are caused to flow out of the reservoir rock and into a wellbore by natural energy gas drives depend on the fact that, as the reservoir is produced, pressure is reduced, allowing the gas to expand and provide the driving energy. Water-drive reservoirs depend on water pressure to force the hydrocarbons out of the reservoir and into the wellbore.The primary reservoir drive mechanisms are:· Gas drive which includes both solution gas drive as well as gas cap drive· Water drive· Gravity drainage· Combination driveProducing oil and gas needs energy. Usually some of this required energy is supplied by nature. The hydrocarbon fluids are under pressure because of their depth. The gas and water in petroleum reservoirs under pressure are the two main sources that help move the oil to the well bore and sometimes up to the surface. Depending on the original characteristics of hydrocarbon reservoirs, the type of driving energy is different.Solution Gas Drive Reservoirs When a newly discovered reservoir is below the bubble point pressure; there will be free gas as bubbles within the oil phase in reservoir. The reservoir pressure decreases as production goes on and this causes emerging and expansion of gas bubbles creating extra energy in the reservoir. These kinds of reservoirs are called as solution gas drive reservoirs. Crude oil under high pressure may contain large amounts of dissolved gas. When the reservoir pressure is reduced as fluids are withdrawn, gas comes out of the solution and displaces oil from the reservoir to the producing wells. The efficiency of solution gas drive depends on the amount of gas in solution, the rock and fluid properties and the geological structure of the reservoir.Water Drive Reservoirs Most oil or gas reservoirs have water aquifers. When this water aquifer is an active one, continuously fed by incoming water, then this bottom water will expand as pressure of the oil/gas zone is reduced because of production causing an extra driving energy. This kind of reservoir is called water drive reservoirs. The expanding water also moves and displaces oil or gas in an upward direction from lower parts of the reservoir, so the pore spaces vacated by oil or gas produced are filled by water. The oil and gas are progressively pushed towards the well bore.Gravity drainage may be a primary producing mechanism in thick reservoirs that have a good vertical communication or in steeply dipping reservoirs. Gravity drainage is a slow process because gas must migrate up structure or to the top of the formation to fill the space formerly occupied by oil. Gas migration is fast relative to oil drainage so those oil rates are controlled by the rate of oil drainage.
How do you know if an engine is a 2 cycle?
the easiest way to determine a 2 stroke from a 4 is if it has an oil reservoir in the engine for motor oil it is a 4 stroke, if it requires oil in the gas then it is a 2. also some 2 strokes will have an auto mix with a reservoir for the 2 cycle oil and another for the gas and it will mix the 2 on its own
Do you have to mix the gas and oil in 1981 115 hp evinrude 4 stroke?
No. Four stroke engines get lubrication from a separate oil reservoir.
