n: a drilling operation in which the drilling fluid is not returned to the surface;rather. it flows into an under- ground formation. Sometimes blind-drilling techniques are resorted to when lost circulation occurs.

n: the technique associated with the improvement of drilling quality and drillig speed

n: (LWD) logging measurements obtained by measurementwhile- drilling techniques as the well is being drilled.

n: The measurement of formation properties during the excavation of the hole, or shortly thereafter, through the use of tools integrated into the bottomhole assembly. LWD, while sometimes risky and expensive, has the advantage of measuring properties of a fo

a technique using a suite of logs that are part of the drilling BHA. The formation properties are measured while drilling (although 40 to 60 feet back from the bit) and the information is pulsed to the surface.

n: a drilling technique that uses air or gas to which a foaming agent has been added.

n: A variation of air drilling in which a small amount of water trickles into the wellbore from exposed formations and is carried out of the wellbore by the compressed air used for air drilling. The onset of mist drilling often signals the impending end of p

n: a directional survey that uses measurement-while-drilling techniques to detem1ine drift angle and azimuth.

n: on the basis of scientific analysis of concluding the drilling data and material, people establishes corresponding drilling data model and according to that model draws up a set of drilling arrangement that enable the quality better , the speed rapadly an

n: the drilling technique that the drilling pipe or collar of pin screw upper and box screw underneath joined together.
