DownHole SAT allows you to visualizes the scale
potential and corrosivity of a water as environmental parameters and
water chemistry change. View the "DownHole
SAT Walk About" tour PDF.
DownHole SAT models brines in three
ways:
Surface
Calculate the indicators of
scale potential and corrosivity versus pH/pCO2, temperature, or both for your
surface water.
Display this chemistry with an array of presentation quality descriptive
tables, 2D and 3D graphs.
Waterflood
Find the properties of your mixed injection and
formation water.
Display this chemistry with an array of presentation
quality descriptive tables, 2D and 3d graphs
Mixture
Enter up to ten (10) different waters, and their relative flows or percentages, and project
the properties of the final mixture.

Scale Formation
DownHole SAT calculates dozens of scale forming species using
French Creek's powerful Ion Association Model - with a range up
to 300°C; 300,000 TDS; and 12,000
PSI - it is used effectively on even harsh North Sea Brines.

Product Input/Formulation
Premium Editions (Formulator and Laboratory Editions) of DownHole
SAT are used extensively by water treatment companies, by Corporate Chemists who wish to evaluate and compare the treatment programs proposed for wells, and by consultants for performing in-depth technical and economic analyses of aqueous systems.
French
Creek's inhibitor models have been developed over
decades of working closely with chemical companies,
derived from lab, field data and extensive experience.
DownHole SAT's users input and formulate products to
be used for dosage modeling and treatment optimization.
Chemists can input up to seven inhibitors at varying
ratios. DownHole SAT allows you to password
protect your proprietary formulas if distributing
product files to a sales force or staff using DownHole
SAT for treatment.
Laboratory Editions offer the ability to create
custom inhibitor models from field and lab data.

Dosage Optimization
Once
you have created product files with your custom formulations, view
the performance of your treatments.
All premium editions of DownHole SAT calculate dosage
profiles of inhibitors; allowing users to test and choose the
most appropriate treatment and each treatment's limits.
DownHole SAT calculates the necessary minimum
affective dosage over your range (pH, mixture,
temperature, pressure etc).
Visual Aids
One of the most powerful and useful features of
DownHole SAT are the 2D and 3D graphs.
Even with little chemistry background, just recognize
blue good, red bad to see where a treatment reaches it's
limits.

Editions
DownHole Rx Engineer's Edition
The Engineer's Edition performs all of the functions and has all of the features of the basic DownHole SAT program. It adds the ability to select a water treatment product and obtain dosage recommendations.
Each table has an additional line for Dosage or Predicted Corrosion Rate in the Rx series, of which the Salesman Edition is the first. An additional graph selection appears for all two (2D) and three (3D) dimensional graphs - the Dosage Profile.
The Engineer's edition can load a Product File (.PRD) for use in determining treatment rates and developing dosage profiles. But, alas, the Engineer's Edition lacks the ability to edit or create Product Files, or even look at the ingredients. They must be created (and edited) using a higher member of the DownHole Rx Series. Both the Formulator and Laboratory Editions can create and edit Product Files.
DownHole Rx Formulator Edition
The Formulator Edition adds the ability to create and edit product files.
Creating a Product File is as simple as filling in a computerized formula (batch) sheet. Product Files can be password protected to maintain confidentiality.
Files so created can be used by the Formulator Edition or copied to the \DHSAT\INHIB sub-directory on other computers with DownHole Rx programs.
Formulator Editions are used extensively by water treatment companies who wish to use the inhibitor models supplied by French Creek, by Corporate Chemists who wish to evaluate and compare the treatment programs proposed for wells, and by consultants for performing in-depth technical and economic analyses of aqueous systems.
DownHole Rx Laboratory Edition
The Laboratory Edition adds the ability to develop scale inhibitor, corrosion inhibitor, and corrosion rate predictive models from laboratory data, field data, or a combination of both.
Dosages (or Rates) can be modeled as a function of any parameters input into the program in their raw form, calculated indices, and other parameters calculated by the program.
Transforms are available and can be applied independently to each variable.
For example, a CaCO3 inhibitor might be modeled:
log(DOSAGE) = f( log(Calcite Saturation - 1), 1./RT, log(time))
This is, in fact, a common model for phosphonate inhibitors.
A simple corrosion rate model might be correlated as follows:
log(Rate) = f( log(Ca), 1./RT, log(Cl), log(SO4 ), pH)
Inhibitor models developed by the Laboratory Edition are output to the .INH files used to develop Product Files. Raw data is stored in .COR files. Statistics are, of course, provided on each variable as you develop a model.
Laboratory Editions are used extensively by scale inhibitor synthesizers, and by major water treatment companies and industrial laboratories doing inhibitor and/or corrosion research.
The Laboratory Edition is used by major inhibitor suppliers, and by top industry consultants.

graph displays the ranges and ratios where corrosion
will occur, and the rate.
