Production Measurement - Invert Orifice Measurement, Contaminant Problems And High Pressure Metering Problems
Author(s): Richard L. Rex
Abstract/Introduction:
Production measurement problems in the area of most of our field production is due to the weather. We have six months cold and snow, two months of rain and the remainder of the year is hot and dry. Most of our well locations are in high altitudes or remote locations. Due to snow and rain the roads to most well locations are in bad condition several months of the year, making tending these wells very difficult. We have solved the chart changing and well tending problems in some areas by using he1icopters.

Fundamentals Of Diaphragm Type Positive Displacement Meters
Author(s): G. O. Christensen Ken Bordner
Abstract/Introduction:
The displacement gas meter is frequently referred to as a positive displacement meter, not because it is any more definite or accurate than measuring with any other type of meter, but because the measurement it affords is a Positive Volumetric quantity in cubic feet at flowing conditions regardless of or pressure the temperature, gravity of the flowing gas.

Flow Computers And Transducerscalibration And Trouble Shooting
Author(s): Lawrence Lanidert
Abstract/Introduction:
In d 1( 1974 Mountain Fuel took a long hard look at the feasibility of more accurate measurement of its interruptible customers gas usage. At that time, consideration was given to the benefits that could be derived from a monitoring system capable of communicating this measured gas usage to our gas control people. These people could then better anticipate gas acquisitionand distribution. With the advent of an imposition of penalties for gas consumed during curtailment periods, Mountain Fuel had to keep a finger on the pulse of its interruptible customers.

Teton Dam Disaster
Author(s): O. R. Burch
Abstract/Introduction:
June 5, 12:30 pm, II was returning from Blackfoot when I overheard a partial radio conversation between Del Russe11 and Marv Pitman. I asked Marv to update me on what was going on and he informed me the Teton Dam had broken and a wall of water was approaching Rexburg and Sugar City. He also informed me which of our people had been made aware of the crisis. Harry Peterlin and Del Russell were on the south side..of the Snake River at the Annis Valve. This valve was selected because of its location to secure shutdown of the 8 lateral going north to Rexburg, Sugar City and St. Anthony.

Th Gas Dispatcher The Field Technician
Author(s): James L. Hamlin
Abstract/Introduction:
Over the past generation, cooperation between the dispatchers and field technicians has become increasingly important. All of a sudden, natural gas, which was once considered nuisance to oil men, is a highly regarded, much in demand, expensive commodity. When a commodity is in demand, its value increases. This is evident by our gas bills today

High Pressure Regulation
Author(s): Rrayrosh-Ny
Abstract/Introduction:
lht is High Pressure Regulation? Generally speaking it is the. closing and opening of a valve to maintain a desired pressure at the downstream side of the valve. Actually, the original regulator was just that - A man opening and closing a valve. A high pressure regulator is just a regulator built to withstand thousands or hundreds of pounds of pressure on the inlet side of it.

Lubricated Plug Valve Maintenance & Repair
Author(s): G. Keith George
Abstract/Introduction:
As. e ol( a type of valve, the plug valve is the oldest style of valve on which we have been able to trace a history. Plug valves have been around for about 3200 years. The original plug valve was a piece of wood that had a hole bored in it. This was inserted in a pieceofpipe, which was then hollowed out bamboo, and when you turned that plug so that the hole in it was in line with the hollow portion of the bamboo (the run of the pipe) you got flow. When you rotated the plug 90 degrees, so that the solid portion was in 1ine with the run, the flow stopped.

Fundamentals Of Pressure Regulation
Author(s): Harold F. Kruzan
Abstract/Introduction:
A pressure regulator is designed to reduce and control pressure. This is done primarily .to provide an adequate safety factor, increase the accuracy of measurement and efficiency of the utilization of the gas, and to increase the economy of the transmission and distribution of gas. A gas pressure regulator must be capable of reducing either a constant or variable pressure to a constant discharge pressure of a lower value.

Metrication Is Here
Author(s): Don J. Hunter
Abstract/Introduction:
It has been said that the history of measurement is the history of mans struggle to understand what his neighbor meant when he was talking of quantity, and then to agree with that neighbor on a description that would have the same meaning for a third party. Before reviewing the status of the metric system (SI), that both our countries are implementing on a voluntary basis, I believe it is important to review a little of that history of measurement that has led to this decision to change from the Imperial or British system to the metric system. Initially to barter, man had to invent systems of measurement to help him in what he was buying and selling.

Turbine Meters: Fundamentals, Installation And Maintenance
Author(s): Jim Can Brad Lawrence
Abstract/Introduction:
Basically the turbine type meter is a vane rotor installed in a stream of flowing gas. The velocity of the gas flow puts a force on the vanes of the rotor and turns it at a speed proportional to the velocity of the gas flow. The turning of the rotor shaft is put through a gear train and transferred up to an index or a correcting device, usually through a magnetic coupling system. (This is used to avoid the use of a packing assembly which has a tendency to leak around the shaft.)

Basic Fundamentals Of Orifice Meter Measurement
Author(s): Ken Kendall
Abstract/Introduction:
Fluid meters are divided into two functional groups - One measures primarily guantity (Positive Displacement) the other measures primarily rate of flow (Inferential.) All fluid meters, however, consist of two distinct parts, each of which has different functions to perform. The first is the primary element, which is in contact with the fluid, resulting in some form of interaction.

Volume Correcting Devices Application And Maintenance
Author(s): Jim Axelton Mike Neeley
Abstract/Introduction:
All gas meters are tested to register the volume of gas in cubic feet at the existing line pressure. With the advent of pipe lines for the transmission and distribution of gas at high pressure, the problem of measurerrent arose with the question: How can gas be measured at high pressure and the volume be expressed as the number of cubic feet which would be measured by a meter at a pressure as low as that at which a cubic foot of gas is assumed to be standard?
