n: the measured initial gel strength of a fluid is the maximum reading taken from a direct-reading viscometer after the fluid has been quiescent for 10 sec. it is reported in 1b/100 ft2

n: the measured 10-min gel strength of fluid is the maximum reading taken from a direction-reading viscometer after the fluid has been quiescent for 10 min. the reading is reported in 1b/100 ft2.

adj: see clabbered.

n: oil-field jargon usually referring to any fluid with high gel strength and/or highly viscous properities. Often a state of severe flocculation.

n: any law relating to the pressure, temperature, or volume of a gas. generalised viscosity cone n: a plot of calibration coefficient versus a modified expression of Reynolds number.

n: schlumberger wireline tool that measures concentrations of 12 elements. The processing quantifies mineral analysis to allow formation analysis in complex lithologies, clay volume and typing,porosity, permeability evaluation, sandstone classification, grai

n: brand name of patented device .it is an device to record voluntarily
penetration speed and well depth.

n: an instrument placed on the surface that .detects vibrations passing through the earths crust. It is used in conjunction with seismography. Geophones are often called jugs. See seismograph.

an instrument that detects vibrations passing through the earth’s crust.

n: the physics of the earth, including meteorology, hydrology, oceanography, seismology, volcanology, magnetism, and radioactivity.

the science of the physical properties of the earth.

n: the increase in the temperature of the earth with increasing depth. It averages about 1�F per 60 feet (1�C per 18.3 metres),but may be considerably higher or lower.

n: 1.The rate of increase in temperature per unit depth in the Earth. Although the geothermal gradient varies from place to place, it averages 25 to 30 oC/km [15 oF/1000 ft]. 2.The natural increase of temperature with depth in the earth. Temperature gradient

the gradient reflecting the amount of temperature rise as the well depth increases. Normally about 1.1 to 1.8o F per 100 ft of true vertical depth increase.

n: spoken language.it is very difficulty to drill in hard layer,the speed is slow which make a comparison to nibbling bone.
