BAKER HUGHES - Drilling Fluids Reference Manual

TABLE OF CONTENTS
ADVANTAGE SM
ADVANTAGE SM is Baker Hughes Drilling Fluids’ integrated platform for all well planning,
reporting and analysis services. This is a modular platform which allows for customized features
depending on services being provided. Drilling Fluids Services include the comprehensive Daily
Fluids Reporting system as well as the Engineering Software System. Engineering Software consists
of Hydraulics and Swab and Surge Analysis
All services above share data within a common integrated multi-well relational database. Data
entered in Reporting Applications can be readily loaded into the Engineering Applications for
rapid analysis. The Engineering Applications themselves are integrated. Analyses can be run for
Hydraulics, Hole Cleaning, HTHP, and Swab & Surge predictive results at one time with the
common dataset either for pre-well planning purposes, or daily operational data.
Standard output reports from all Engineering Applications include Input Data and Calculated
Results. In addition, ancillary reports (such as drill string and survey listings) are available. Also,
all Engineering modules have interactive on screen graphic presentations of results. These results
can be cut and pasted into standard MS Office applications (as graphics or data) for supplemental
output.
More specific information on ADVANTAGE SM Modules is provided below.
ADVANTAGE SM Engineering Hydraulics
Advantage Hydraulics provides sophisticated mathematical hydraulics and hole cleaning models.
It is designed to give the best available estimate of the flow rate required to maintain effective hole
cleaning. The program has been developed by a combination of theoretical modeling and field
verification.
Hydraulics calculates the following:
• Total system pressure loss
• Maximum and minimum allowable flow rates for the given hole and drillstring configurations
• Annular velocities
• Hydraulic horsepower at the bit
• Equivalent circulating density (ECD)
• Can be set to run several standard rheology models including: Bingham Plastic, Power Law,
Newtonian, Hershel-Bulkley and Robertson-Stiff.
ADVANTAGE SM HTHP Analysis
When ADVANTAGE SM is run in the HTHP analysis mode, it considers the influence of pressure
and temperature on the mud density and viscosity. The temperature profile can either be calculated
or defined. The calculation of downhole density based on pressure and temperature requires the
knowledge of the mud density profile. This can be provided by mud density measurements or by
calculating the density based on the mud components. The results are displayed graphically in the
Hydraulics Results Window. The calculation of mud rheological properties requires Fann70
readings. These data must cover the range of pressures and temperatures expected in the well. The
calculation performed is similar to a System Mud Hydraulics calculation. Additional results are
created. There is an effective mud weight and a temperature profile report. Both are available
