GNA aims at achieving a penetration rate of […] % of all households within […] months (and penetration levels are expected to be saturated approximately at this level).
Advantageously, friction between the drill string and bore hole is reduced, leading to an increase in the drilling penetration rate.
A method of increasing the penetration rate of a drill string (2) within a deviated well bore is disclosed.
The present invention provides a method and apparatus for estimation of general and localised corrosion penetration rates of metallic materials and objects.
A masonry drill bit (20) having an improved insert geometry, insert orientation, and interface clearance for providing improved drill speed and penetration rate.
A computer model may be used to evaluate the work-force and/or the sliding-wear rates that cutting elements of the bit experience as compared with the rate-of-penetration and/or durability of the bit.
A method of carbonitriding which can improve the rate of nitrogen penetration to enable a carbonitriding treatment to be conducted efficiently.
A method for predicting the rate of penetration (ROP) of a drill bit drilling a well bore through intervals of rock of a subterranean formation is provided.
The unique combination of mechanical and hydraulic cutting results in higher rates of penetration and improved productivity.
When used as lubricants and/or rate of penetration enhancers, the olefin isomers preferably are used alone or in combination with surfactants.
The device comprises an injector and an enhancer for enhancing the rate of penetration of the substance into the subject.
In response to receiving input from an external device, the device provides providing the theoretical rate of penetration and the theoretical drilling distance.
The rolling cutter may be positioned, relative to the fixed blades, to also limit rate of penetration and/or exposure of the fixed-blade cutting elements.
A rotary drill bit with cutting elements operable to control depth of cut and rate of penetration during formation of a wellbore are provided.
Suitably positioned sensors make dynamic measurements of parameters such as downhole weight on bit, bit torque, bit revolutions, rate of penetration and bit axial acceleration.
The lubricating composition is suitable for use as a lubricant and rate of penetration enhancing additive in drilling muds for oilwell drilling operations.
The present invention relates to a drilling fluid additive for improving lubricity or rate of penetration (ROP) in a drilling operation, such as an oil and gas drilling operation.
Rotary shaft seals for compressors or blowers specified in 0B001.c.3. and designed for a buffer gas in-leakage rate of less than 1000 cm3/min.
