The hole drilled for the purpose of producing oil and gas, or to inject water or other fluids. The wellbore includes the openhole or uncased portion of the well

Dew point is defined as the temperature at which vapor begins to condense.

Dewpointing removes the liquid vapors from the gas to prevent the formation of slug in the pipeline

Water dew-point is to prevent the condensation and accumulation of water at low points in the pipelines. The water dew-point specification is usually achieved by removing water vapour from the process gas stream using different dehydration or other technologies.

A WPS is a document that describes how welding is to be carried out in production.  They are recommended for all welding operations and many application codes and standards make them mandatory. They should include sufficient details to enable any competent person to apply the information and produce a weld of acceptable quality

A reduction in the permeability of a formation caused by the invasion of water into the pores

The equipment installed at the surface of the wellbore.  A wellhead includes such equipment as the casinghead and tubing head. The point at which the crude (and/or natural gas) exits the ground. Following historical precedent, the volume and price for crude oil production are labeled as “wellhead,” even though the cost and volume are now generally measured at the lease boundary. In the context of domestic crude price data, the term “wellhead” is the generic term used to reference the production site or lease property

A well drilled to (1) obtain a water supply to support drilling or plant operations, or (2) to obtain a water supply to be used in connection with an improved recovery program

A measure of the resistance of a fluid to flow.  Resistance is brought about by the internal friction resulting from the combined effects of cohesion and adhesion.  The viscosity of petroleum products is commonly expressed in terms of the time required for a specific volume of the liquid to flow through a capillary tube of a specific size at a given temperature.
