PSI/Readingโ๏ธ Pressure Regime Classification
๐ Ratio-Based Pressure Regime Model
โ ๏ธ Important: This is a Pressure Regime, Not True Phase Detection
True phase identification (Oil/Gas/Water) requires PVT analysis, fluid sampling, or compositional/density logs โ it cannot be done from pressure and temperature alone.
What this tool does is classify each reading into three pressure regimes, labelled Gas / Oil / Water for convenience. These labels correspond to likely depth zones in a typical well, not measured fluid composition.
๐ The Formula
ratio = pressure (PSI) / (temperature (ยฐC) + 273)
Adding 273 converts temperature to Kelvin so the ratio is dimensionless and physically scaled.
๐ฏ Adaptive Thresholds (NEW)
Fixed thresholds (e.g. 0.15 / 0.35) don't work across wells with different pressure ranges. This tool now computes thresholds automatically from your own dataset โ using the 33rd and 66th percentiles of the ratio distribution.
Result: each regime always gets a meaningful share of readings, regardless of whether your gauge sees 10 PSI or 10,000 PSI.
You can also override with manual thresholds below if you have a specific calibration in mind.
โฝ Low-Regime ("Gas")
Meaning: Lowest ratio band โ typically corresponds to surface / near-atmospheric conditions or actual gas zones.
Threshold: ratio < low cutoff
๐ข๏ธ Mid-Regime ("Oil")
Meaning: Middle ratio band โ typically the tubing/oil column zone in a flowing well.
Threshold: low โค ratio < high cutoff
๐ง High-Regime ("Water")
Meaning: Highest ratio band โ typically bottom-hole / reservoir conditions or water leg.
Threshold: ratio โฅ high cutoff
๐ก Tunable & Transparent
The exported CSV/JSON includes the raw ratio for every reading so you can re-classify later with any cutoffs you want, or feed the data into a proper PVT/compositional model.

๐ Data Dictionary - Understanding Your Numbers
๐ด Pressure Metrics Explained
Definition: The lowest pressure value recorded in the entire dataset.
Formula: MIN(all pressure readings)
Unit: PSI (Pounds per Square Inch) or BAR (metric)
Why it matters: Indicates minimum well pressure conditions and system integrity.
Example: If Min = 1.18 PSI, the well reached its lowest pressure at 1.18 PSI during the monitoring period.
Definition: The highest pressure value recorded in the entire dataset.
Formula: MAX(all pressure readings)
Unit: PSI (Pounds per Square Inch) or BAR (metric)
Why it matters: Shows peak pressure conditions and maximum system load.
Example: If Max = 2557 PSI, the well reached 2557 PSI at peak conditions.
Definition: The mean (arithmetic average) of all pressure readings.
Formula: SUM(all readings) / COUNT(all readings)
Unit: PSI or BAR
Why it matters: Represents typical operating pressure and overall system behavior.
Example: If Avg = 1670 PSI, the well operated at an average of 1670 PSI.
Definition: Measures how much pressure values vary from the average. Higher = more variation.
Formula: โ(ฮฃ(value - average)ยฒ / n)
Interpretation:
- Low Std Dev = stable, consistent pressure
- High Std Dev = fluctuating pressure conditions
Example: If Std Dev = 456 PSI, readings typically vary ยฑ456 PSI from the average.
๐ต Temperature Metrics Explained
Definition: The lowest temperature value recorded.
Formula: MIN(all temperature readings)
Unit: ยฐC (Celsius) or ยฐF (Fahrenheit)
Why it matters: Shows coolest well conditions and temperature range.
Example: If Min = 22.0ยฐC, the well cooled down to 22ยฐC minimum.
Definition: The highest temperature value recorded.
Formula: MAX(all temperature readings)
Unit: ยฐC or ยฐF
Why it matters: Shows hottest well conditions and thermal stress.
Example: If Max = 27.4ยฐC, the well heated up to 27.4ยฐC at peak.
Definition: Mean temperature across all readings.
Formula: SUM(all readings) / COUNT(all readings)
Unit: ยฐC or ยฐF
Why it matters: Typical operating temperature for the well.
Example: If Avg = 27.1ยฐC, the well typically operates at 27.1ยฐC.
Definition: Temperature variation from the average.
Formula: โ(ฮฃ(value - average)ยฒ / n)
Interpretation:
- Low Std Dev = stable temperature control
- High Std Dev = significant temperature fluctuations
Example: If Std Dev = 2.3ยฐC, temperatures vary ยฑ2.3ยฐC from average.
๐ Pressure Gradient Metrics Explained
Definition: Average pressure change from first to last reading, divided by number of readings.
Formula: (Final Pressure - Initial Pressure) / (Number of Readings - 1)
Interpretation:
- Positive value = pressure increasing over time
- Negative value = pressure decreasing over time
- Value close to 0 = stable pressure
Example: If Per Reading = 0.5 PSI/Reading, pressure increases by 0.5 PSI per measurement.
Definition: Rate of pressure change per hour of operation.
Formula: (Final Pressure - Initial Pressure) / Duration (in hours)
Unit: PSI/Hour or BAR/Hour
Why it matters: Shows how quickly pressure is changing (buildup or drawdown rate).
Example: If Per Hour = 5.2 PSI/Hour, pressure increases by 5.2 PSI every hour.
Definition: Average absolute change between consecutive readings (ignores direction).
Formula: SUM(|ฮP between readings|) / Number of Readings
Interpretation: Shows how much pressure fluctuates regardless of direction.
Why it matters: High values indicate unstable/volatile pressure conditions.
Example: If Avg Change = 2.1 PSI, readings typically jump ยฑ2.1 PSI from one to the next.
Definition: Net pressure change from the very first to the very last reading.
Formula: Final Pressure - Initial Pressure
Interpretation:
- Positive = overall pressure buildup
- Negative = overall pressure decline
Example: If Total = 50 PSI, the well's pressure increased by 50 PSI overall.
โ๏ธ Phase Statistics Explained
Definition: How many readings were detected as this phase.
Example: If Oil Count = 1200, there were 1200 readings classified as oil phase.
Definition: Percentage of total readings that belong to this phase.
Formula: (Phase Count / Total Readings) ร 100%
Why it matters: Shows which phase dominates the well production.
Example: If Oil = 45%, then 45% of all readings were oil phase.
Definition: Pressure statistics for only the readings in this phase.
Why it matters: Shows typical pressure range when this phase is dominant.
Example: If Oil Min = 100 PSI, the lowest oil-phase reading was 100 PSI.
Definition: Temperature statistics for only the readings in this phase.
Why it matters: Shows typical temperature conditions when this phase is dominant.
Example: If Water Avg Temp = 45ยฐC, water phase readings averaged 45ยฐC.
