n: The unalterable objective element that affect the rate of drilling and cost in optimum parameter drilling ,for example ,geologic condition,strata behavior and burial depth.

n: The general collar that have a row of blind hole at one side face,which can decrease the well deviation.

n: This kind of three-cone bit has a major jet,which can buildup well deviation at designed direction,usually be used in side track.

n: The general collar that have a row of blind hole at one side face,which can decrease the well deviation.

n: The ways that can make the cuttings and clod on the cone or tooth of bit falling off through the measure of picking up ,setting down and rotating the drill string .

n: The derrick that havent cover of keeping out of wind and cold.

n: in pipeline construction, a road crossing bored without casing. The carrier pipe itself is pushed under the roadbed by the boring machine. To reduce potential damage to the coating, slick boring is frequently used. See slick boring.

the amount of possible inaccuracy.

a reflection of the measured or perceived possible range of outcomes associated with an event or process. Uncertainty can be expressed as deterministic quantitative value, a qualitative value, or as a probability distribution that combines a range of quan

the process of combining uncertainties, as with a Monte Carlo Simulation, to generate output parameters that are represented by probability distributions. No involvement of risk is implied. Example: multiplying ranges of length and width to arrive at a ra
