n: a paste that is applied to an ullage rule or dip tape and weight to indicate precisely the level at which the liquid meniscus cuts the graduated portion.

n: It have good fluidity,low filter loss,high intensity and low permeability,which be used in the cementing at low-pressure and cracky layer or high temperature well.

n: (ULCC) a supertanker whose capacity is 500,000 dead- weight tons or more. Compare very large crude carrier.

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

n: The drill fluid that dont contain the heavy weight additive.

n: The load obtained from the total load substracting itself weight .

n: The rock be breaked into big blocks,when bit weight per unit area equal to or exceed the hardness of rock.

abbr: weighted average cost of gas.

a method of controlling kicks in which the weight of the kill weight mud is calculated by the difference between the difference of casing and tubing pressure and the volume of fluid increase;followed by injection of the kill weight mud to displace the li

n: a well-killing method in which the well is shut in and the mud weight is raised the amount required to kill the well. The heavy mud is then circulated into the well while the kick fluids are circulated out. So called because one shuts the well in and waits for the mud to be weighted before circulation begins.
