n: a measure of the ability of a single fluid (such as water, gas, or oil) to flow through a rock formation when the formation is totally filled (saturated) with that fluid. The permeability measure of a rock filled with a single fluid is different from the permeability measure of the same rock filled with two or more fluids. Compare effective permeability, relative permeability.

permeability to a single phase fluid in a cleaned core.

n: The process that various drilling fluid samples react totally in the certain condition through a period.

n: The time when the samples totally react in the certain condition.

n: a glass-stem thermometer totally encased in a glass sheath, which provides air space between the thermometer and the liquid in which the unit is immersed.

n: a glass-stem thermometer in which the tail is bent at an angle to the stem so that the tail can be mounted in a horizontally disposed thermowell, leaving the scale vertical for greater ease of reading.

n: reduction in service or purchases below contracted-for levels. Curtailment of gas sales service is a method of balancing a utilitys natural gas requirements with its natural gas supply. There is usually a hierarchy of customers for the curtailment plan based on priority of usage according to established regulatory standards of priority. A customer may be required to cut back partially or totally to eliminate this take of gas, depending on the severity of the shortfall between gas sup- ply and demand and the customers position in the hierarchy. From the customers standpoint. curtailment may also mean a reduction by the customer of its takes of gas from its supplier. Curtailment of a transportation service occurs when demands for service exceed the capacity of the pipeline. Capacity curtailment is based on contract rather than end-use priority. All interruptible service must be entirely curtailed before any firm service is curtailed. Currently, interruptible transportation service is curtailed based on position in the firstcome, first-served queue. Firm transportation service is usually curtailed on a pro rata basis.

n: see deviation.

n: One of the coordinates used to plot the path of the well on the horizontal plane (alone the x axis).

the distance from the kelly bushing horizontally to the end of the well.

n: a cumulus cloud that lies horizontally and shows little vertical development, indicating good weather conditions.

n: person appointed by a court of competent jurisdiction for the purpose of managing property and rights for another person who is considered incapable of managing for himself or herself-for example, a minor child, a mentally ill person, or someone judged mentally incompetent.

v: to suspend sucker rods in a derrick or mast on rod hangers rather than to place them horizontally on a rack.
