What is steamflood in oil and gas?

What is steamflood in oil and gas?

1. n. [Heavy Oil, Enhanced Oil Recovery, Well Completions] A method of thermal recovery in which steam generated at surface is injected into the reservoir through specially distributed injection wells. When steam enters the reservoir, it heats up the crude oil and reduces its viscosity.

What is the depth limit for steam flooding?

Heat losses are high through injection lines, wellbores and oil well formation. Steam flooding requires large supply of high quality fresh water. Steam injection is limited to depths shallower than 5000 ft because of high reservoir pressure and temperature losses.

How does steam flooding work?

Steamflooding is a process used by Chevron to increase recovery from heavy oil reservoirs. In steamflooding, steam is injected near the base of a heavy oil reservoir through an injection well. The injected steam vapor rises toward the top of the reservoir due to buoyancy.

Why do steam injections recover oil?

The injection of steam lets heat the crude oil in the formation thus lowering its viscosity and vaporizing some of the oil to increase its mobility. [4] The decreased viscosity helps reduce the surface tension, increase the permeability of oil and improve the reservoir seepage conditions.

What is direct steam injection?

Direct Steam Injection works by directly injecting steam into a process fluid to obtain more rapid heat transfer, resulting in more efficient energy usage than indirect heat exchangers.

Where are the two largest reserves of oil sands?

Oil sands are found in various countries throughout the world, but in vast quantities in Alberta and Venezuela. Alberta’s oil sand reserves are estimated at 1.7 to 2.5 trillion barrels of oil trapped in the complex oil sand mixture, and this represents the largest single reserve of oil in the world.

What is a Hydroheater?

What is a Jetcooker? The Hydroheater® is the original and most advanced Jetcooker™ because it fully adjusts shear mechanically and utilizes the eductive energy of steam creating a shockwave in the condensation (heat transfer) process.

What is SAGD operation?

Steam-assisted gravity drainage (SAGD) is a drilling technique used to extract heavy crude oil which is buried too deep or otherwise burdensome to access.

What is Hydroair?

A hydro air system is a combination of a hot water and a hot air system. A hot water boiler, either oil or gas fired, generates heat. The water is then pumped through small diameter tubing to an air handler unit. This unit contains a hot water coil, an air conditioning coil, and a fan (blower) unit.

Are Hydro air systems efficient?

Hydro-air systems are as efficient or more efficient than conventional forced-air furnaces. If your home uses an older forced-air furnace and water heater, upgrading to a hydro-air system will let you replace both appliances with a single, high-efficiency system.

Who invented SAGD?

Considered the father of steam assisted gravity drainage (SAGD), Butler-while employed with Imperial Oil in the 1970s-first developed the concept of using horizontal pairs of wells and injected steam to develop certain deposits of bitumen considered too deep for mining.
