мягенькая клавиатура Kiiboom Phantom 68 Youtube Sagd is a thermal method for recovering heavy oil. the process uses twin horizontal wells drilled and extended into the base of a reservoir with the horizontal steam injector placed directly above the horizontal production well. This document discusses steam flooding techniques for extracting heavy crude oil from oil sands. it describes how steam injection is used to heat oil sands and decrease the viscosity of bitumen, allowing it to more easily flow toward production wells. specifically, it outlines steam assisted gravity drainage (sagd) which uses a pair of horizontal wells steam is injected into the upper well.

Steam assisted gravity drainage (sagd) is an outstanding example of a steam injection process devised for exploitation of heavy oil or bitumen reservoirs utilizing horizontal wells. it is widely used in alberta canada, russia, and china for recovery of heavy and extra heavy oilsands resources. There are many other engineering considerations for sagd such as recovery rate, thermal efficiency, the capability and economics of drilling horizontal well pairs, steam quality, steam injection rate, steam pressure, minimizing sand production, reservoir pressure maintenance and water intrusion; however, their importance is not key to the. In this paper, sagd with a combination of vertical and horizontal well (vh sagd) technology was adopted, and the influence of different well spacings (horizontal distance between vertical steam injection wells and horizontal production wells) on the development of steam chambers was investigated.

The basic mechanism in sagd is that heavy oil is heated up by injected steam from the injection well, and as a result the heavy oil becomes less viscous and mobile and can be produced from the production well. Sagd (butler 1981) employs a pair of parallel horizontal wells, which are drilled in a reservoir, to heat and produce bitumen. the producer is located approximately 2 meters above the base of the reservoir and the injector is about 5 to 10 meters above the producer. steam is injected into the reservoir through the injection well to create a steam chamber. with the steam continually injected. Sagd stands for steam assisted gravity drainage. for oil sands formations that are well below the surface (300m – 500m deep), the sagd process is a means by which the oil can be extracted from the formation. Abstract steam assisted gravity drainage (sagd) is a thermal recovery technology used to produce heavy oil and high viscosity bitumen from alberta oil sands. the oil sands of alberta are unconsolidated sands which require sand control within the horizontal wellbores to reduce the erosive power of the sand and plugging of sand control screens.
