George King is a technology provider in the oil and gas industry specializing in new technology and problem oil well solutions.
A sharp, sometimes very high force and pressure load that is created when a valve is closed too rapidly in a flowing stream. The major force occurs behind the valve. Most common in a production well when sudden closure (slam closure) of a subsurface safety valve can create a load of over 50,000 lbs force in the tubing tensile/compressive loading. In an injector, the water hammer effects of a rapid shut-in are lower, but some effects may be seen on the formation.
Industry:Oil & gas
A short lived state. Generally used describing reservoirs during production as pressure is progressively drawn down near the wellbore and slowly permeates the rock outward.
Industry:Oil & gas
A short piece of casing run one to two joints above the end of casing. The collar contains a backpressure or check valve which stops cement from reentering the well after displacement into the annulus. It is useful to prevent channels in the cement until the cement is set.
Industry:Oil & gas
A short piece of pipe, usually with a profile shape in the ID. Nipple profiles are used in tubular strings to provide places to set plugs.
Industry:Oil & gas
A short section of a tool or pipe that is formed at an angle or is modified downhole by a motor to assist in entering deviated wellbores or drilling off the path of the wellbore.
Industry:Oil & gas
A short section of casing or tubing used as a depth identifier to a collar locator log or used at the top of the well when spacing out a string prior to hanging the string.
Industry:Oil & gas
A short section of casing with a rounded nose of a drillable material and a port through the center to allow circulation.
Industry:Oil & gas
A short section of pipe with the proper threads cut into each end to join two pieces of pipe or equipment that do not have matching connections.
