a fault along which there is increasing offset or separation along the strike of the fault plane. Measured from the initial point of separation.

hydraulic multi-service valve.

n: during drilling ,because of the pressure difference of fluid column pressure in the well and formation pressure ,the cuttings hug closely to the bottom ,as a result ,the cuttings cant be flushed immediately .

n: the rope block the casing to prevent the shocking during pulling casing onto drilling paltform

n: the alternation of any point on wellbore

n: a large funnel- or cone-shaped device into which dry components (such as powdered clay or cement) can be poured to mix uniformly with water or other liquids. The liquid is injected through a nozzle at the bottom of die hopper. The resulting mixture may be drilling mud to be used as the circulating fluid in a rotary drilling operation, or it may be cement slurry to be used in bonding casing to the borehole.

n: a large funnel-shaped device into which dry material (e.g.cement or powdered clay)can be poured.the purpose of the hopper is to mixthe dry material with the liquids injected at the bottom of the hopper.

mixing chamber where dry components can be evenly mixed with liquids. The dry materials are introduced at the bottom of the hopper through a nozzle.

n: a directional well that reaches an inclination of 90 degree

for a strict definition, a 90o deviated well. Actually the well covers a range of “highly” deviated wells (80o to >90o). In the strictest terms, the deviation is measured as 90o from vertical, but tilting bedding planes may make the deviation to the beddi

n: a block of the earths crust that has been raised (relatively) between two faults. Compare graben.

a block of the formation that has been raised between two faults.

n: a method of thermal recovery in which water at the boiling point is injected into a formation to lower the viscosity of the oil and allow it to flow more freely toward producing wells. Although generally less effective than steam injection because of lower heat, hot waterflooding may be preferable under certain conditions, such as formation sensitivity to fresh water or high pressures.
