Downhole Motors - Turbines- Turbine ObservationsTurbine Observations• There is minimal surface indication of a turbine stalling.• Turbines do not readily allow the pumping of LCM.• Sand content of the drilling fluid should be kept to a minimum.• Due to minimal rubber compo…Read More
Downhole Motors - Turbines- Directional TurbineDirectional TurbineThis is a short tool which has a set number of stages and its bearing sectionentirely within one housing. That is, it is not a sectional tool and will betypically less than 30 feet long. It is designed for …Read More
Downhole Motors - Turbines- Bearing SectionBearing SectionUsually, thrust bearings are made up of rubber discs (Figure 5-24) whichare non-rotating (being fixed to the outer housing of the tool) and rotatingsteel discs attached to the central rotating shaft. Long beari…Read More
Downhole Motors - Turbines- Turbine CharacteristicsTurbine Characteristics• Torque and RPM are inversely proportional (i.e. as RPM increases,torque decreases and vice versa).• RPM is directly proportional to flow rate (at a constant torque).• Torque is a function of flow rate…Read More
Enhanced oil recoveryEnhanced oil recovery (abbreviated EOR) is the implementation of various techniques for increasing the amount of crude oil that can be extracted from an oil field. Enhanced oil recovery is also called improved oil recovery or…Read More
