in radioactive logging, the length of time that the system requires to recover after counting an event.

n: the sheave on the crown block over which the deadline is reeved.

n: a device that uses a solvent to reflux, or flow back over, a sample to clean it. Such a device extracts oil or salt-laden water efficiently without harming the core samples.

n: the act of ending federal government control of the wellhead price of new natural gas sold in interstate commerce. Also called deregulation.

v: to increase the depth of a well. Deepening is generally a workover operation carried out to produce from a deeper formation or to control excessive gas found in the upper levels of a reservoir.

n: Increasing depth of wellbore. Usually it is a workover operation.

n: a device made up in the drill string that causes the bit to drill at an angle to the existing hole. It is often called a kickoff tool. because it is used at the kick-off point to start building angle.

n: See kickover tool.

n: the dispersion of solids that have stuck together in drilling fluid, usually by means of chemical thinners. See flocculation.

n: (1) The process of thinning the drilling fluid by bonding with (neutralizing or covering) the positive electrical charges of drilling fluid additives to prevent one particle of drilling fluid from being attracted to another particle. (2) Breakup of flocs

dispersing a clump or a gathering or “flocculated” of particles. Usually accomplished by dispersants or solvent thinners.

n: a well drilled in an existing field to determine, or delineate, the extent of the reservoir.

a secondary well, after a field discovery well, drilled to help determine field extent, volume or potential rate.

n: (DC) the total daily rate that seller maintains and can deliver on demand over an extended period to buyer. delivery gas n: natural gas delivered to a distribution point, such as a gas plant or a city gate. Compare redelivery gas.

n: A method of examining overflowing or leakage in the wellbore. Acquiring difference of circulating rate by computing the difference of delivery capacity and return flow of pump with electro magnetic current meter.
