a dimensionless measure of time often used in analyzing pressure behavior during the hydraulic fracturing process.

a log-log plot that is very useful in predicting when the fracture is in tip-screen-out mode and whether the fracture is being widened or height growth is occurring.

an approximation of a filter’s ability to remove particles of a certain size or larger. Often does not perform at this level until a filter bed of particles builds up on the upstream side of the filter.

n: nominal height of racking paltform refers to the vertical height from the back plane of derrick leg base plate to the back plane of money board.

nj: any drilling fluid, usually oil-base or invertemulsion muds, whose continuous phase dose not co9nduct electricity, e.g.oil. The spontaneous potenial and normal resistivity can not be logged, although such other logs as the induction, acoustic velocity etc

n: a provision in a joint operating agreement that allows parties who consent to later operations to penalize parties who do not consent. The penalty can be arranged in various ways but, to be effective, it assumes the productiveness of the proposed operation.

n: the fluid that is compitable with the product layer and made of solide grains. Which for the purpose of protecting the oil layer when using the overbalance drilling method or complection.

n: in pipeline construction, testing designed to evaluate the quality of both production and field welds without altering their basic properties or affecting their future usefulness. The most common nondestructive testing is radiographic, or X-ray, testing. Compare destructive testing.

n: a person who owns a severed portion of a royalty interest but who does not execute leases, participate in bonuses or rentals, or have rights of exploration and production.

n: a dip-slip fault along which the hanging wall has subsided relative to the footwall.
