SOLUTIONS · DOWNHOLE WELLS
AvailableDownhole and produced water chemistry.
Injection, production, and disposal chemistry at real reservoir conditions — from the formation and injection analyses you already collect on the account. High-TDS brines, mixing incompatibility, and pressure and temperature gradients down the wellbore. Modeled properly, not screened with an index built for cooling water.
WHAT GOES WRONG
What goes wrong in these systems
Extreme brines are exactly where a dilute-solution index calculator fails — and where incompatible mixing drops scale where you cannot mechanically reach it.
Incompatible water mixing
Seawater or aquifer injection water meets formation brine and drops sulfate scale where you cannot reach it — the failure the program is hired to prevent.
Scale in the near-wellbore, tubing, and topside
Calcite from CO₂ pressure drop, barite and celestite from sulfate mixing, halite from evaporative and temperature effects, iron sulfide and iron carbonate.
Sweet and sour corrosion
CO₂ and H₂S driven attack, under-deposit corrosion, and material selection for sour service.
Reservoir souring
Sulfate-reducing bacteria after seawater injection turn a waterflood into a souring problem the account will hold the program to.
Inhibitor squeezes that come back early
Squeeze treatments return too soon because the design assumed the wrong scaling envelope.
Produced water handling
Reuse and disposal compatibility decisions made without a defensible mixing and precipitation case you can take to the account.
WHAT AQUAADVISOR MODELS
What AquaAdvisor models
Full speciation in high-ionic-strength brines — specific-interaction activity models, not a dilute-solution approximation.
- Full speciation in high-ionic-strength brines using specific-interaction activity models
- Saturation and precipitation potential for calcite, barite, celestite, anhydrite and gypsum, halite, siderite, iron sulfides, and silica across the temperature and pressure profile
- Mixing and compatibility for any ratio of injection to formation water — precipitation mass and location along the flow path
- Pressure- and temperature-dependent chemistry down the wellbore and through topside separation, including CO₂ partitioning and degassing
- Sweet and sour corrosion regime prediction and material screening
- Scale inhibitor demand, minimum effective concentration, and squeeze design and squeeze-life estimation
- Souring risk from sulfate availability and microbiological conditions
- Produced water reuse and disposal compatibility, including blending scenarios
DATA BY FIDELITY
Required data inputs by tier
Start with the formation and injection analyses you already collect on the account. Sharpen as residual monitoring and wellhead instrumentation land.
Baseline
- Formation and injection water analyses
- Wellhead temperature and pressure
- Production and injection rates
Instrumented
- Routine sampling cadence
- Residual inhibitor monitoring
- Corrosion monitoring
Hourly speciation
- Continuous wellhead instrumentation
- Hourly chemistry state estimation
OUTPUTS
Outputs and decisions enabled
Every chemistry result carries residual, database, activity model, and solver tier.
- Injection water source and blend selection with precipitation mass and location
- Inhibitor selection and squeeze scheduling with squeeze-life estimation
- Material and metallurgy screening for sweet and sour service
- Workover planning inputs from predicted near-wellbore and tubing scale
- Produced water reuse and disposal compatibility cases
- Defensible basis-of-design record for waterflood and EOR programs
Decisions enabled
What you can decide
- Which injection blend avoids barite or celestite drop-out along the flow path
- When to re-squeeze based on modeled life rather than calendar habit
- Whether metallurgy on the account matches the predicted sweet/sour regime
- Whether produced water on the account can be reused or must be disposed as blended
