The Density Of Rich Natural Gas Mixtures
Author(s): James T. R., Jeffrey L.Savidge
Abstract/Introduction:
A major programme of work is being undertaken at NEL to establish reference-quality measurements of density for ten natural gas mixtures typical of those recovered from North Sea condensate fields. The measurements are being made using the UKs primary standard densitometer for gases over a range of pressures and temperatures commensurate with typical metering conditions. A description of the modified apparatus is presented together with preliminary findings for the first three mixtures.

Fluidic Pressure Pulse Transmitting Flowmeters For Remote Oil Flow Measurement
Author(s): H Wang, G H Priestman, S B m Beck, R F Boucher
Abstract/Introduction:
Details are given of the development of no-moving-part fluidic devices for the measurement of oil flow deep in the production string where the flow is single-phase. Two devices have been investigated which generate pressure pulses at a frequency proportional to the flowrate.

Paper Withdrawn
Author(s): C. J. Freitas
Abstract/Introduction:
This report describes the final work undertaken to achieve the equation which is being balloted in ISO/TC 30/SC 2 for inclusion in ISO 5167-1. It is described as the Agreed Equation since it has the support of the ISO/TC 28 delegation. It includes a description of the work done to check that a change in the expansibility equation would not have a significant effect on discharge coefficient equations fitted to the database.

Verification Of Meter Performance And Well Allocation By Data Analysis.
Author(s): Frank Kemp
Abstract/Introduction:
The Statfjord field is now past peak production. Sub-sea tie-in of satellite fields to the Statfjord C platform requires the use of well allocation by test seperator for ownership allocation between fields.

Computation Of Flow Through Bends
Author(s): J A Sattary, m J Reader-Harris, L A Johnstone
Abstract/Introduction:
Computations have been performed for flow through a single 90 swept bend and through two 90 swept bends, both in the same plane (S-configuration) and in perpendicular planes. Further computations were carried out in which the two bends were separated by a distance of 9D.

Comparison Test And Calibration Of Coriolis Meters
Author(s): John m. Eide, Stephen C. Gwaspari
Abstract/Introduction:
Coriolis Mass Meters are just as accurate and linear as many Turbine Meters. They should be calibrated under the same conditions as they are to be operated at otherwise metering errors of up to 3% can be experienced. The meters zero stability are good and not influenced by increasing pressures or temperatures. They also show a small viscosity dependent effect on readings.

Crude Oil And Condensate Expansion Co-Efficients
Author(s): R Third, N Colyer
Abstract/Introduction:
A Venturi flowmeter is expected to produce a discharge coefficient of less than unity. Laboratory work at NEL, for Shell Expro, on a series of 150 mm (6 inch) diameter Venturi flowmeters, has resulted in discharge coefficients of several percentage points higher than predicted, according to ISO 5167-1 1991.

Sampling 3-PHASE Fluids Gas(, Hydrocarbon Liquid, And Water) For Quality Determination
Author(s): Thomas F Welker
Abstract/Introduction:
The proper sampling of a 3-phase stream, like measurement, is decidedly more difficult than most engineers and operations people think. In order for this important step in the measurement process to be accomplished properly, the rules of sampling must be followed to the letter.

Historic Use Of Downer Equation
Abstract/Introduction:
Use of the API 11.2.1 M tables (or equation) is comparatively new in the UK. A similar (not identical) function was previously performed by use of the Downer equation. This calculated a compressibility value for the crude, but took no account of the vapour pressure of the liquid.

Abstract/Introduction:
Matching of multiphase meter (MPM) capabilities with field conditions has allowed exceptional performance in applications in Indonesia. Texacos Starcut microwave sensor is unique in its ability to provide very accurate and stable WaterCut determination (0.3% rms. error) at very high watercuts (90%) even when some gas is present in the fluids and salinity is varying.
