The development or increase in the size of this organ stops at the age of 25 or 26. When the kidney stops to increase in size, the average length usually reaches 12 centimeters while the breadth is approximately 6 centimeters.
Artificial lift is needed in wells when there is insufficient pressure in the reservoir to lift the produced fluids to the surface, but often used in naturally flowing wells (which do not technically need it) to increase the flow rate above what would flow naturally.
Power sources: The availability of electricity or natural gas governs the type of artificial lift selected. Diesel, propane or other sources may also be considered. Field location: In offshore fields, the availability of platform space and placement of directional wells are primary considerations. In onshore fields, such factors as noise limits, safety, environmental, pollution concerns, surface access and well spacing must be considered.
