Petroleum Gas Coning Height Calculator
Audit actual independently observed gas static/producing contact shift in same downward-positive depth datum, positive convention=gas downward, negative retreat/unknown evidence retained; no coning prediction. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
Coning-height observations compare static and producing fluid-contact depths under a shared datum.
Coning-height observations compare static and producing fluid-contact depths under a shared datum.1
This gas tool keeps signed observed movement and counts unavailable assessments rather than predicting a contact position.
When to use Petroleum Gas Coning Height Calculator
Use this tool when you need to calculate the stated measurement summary or conditional model from matched observations. Prepare completed matched measurements, SI or explicitly stated oilfield units, and independent evidence for the selected branch or calibration.
How to use Petroleum Gas Coning Height Calculator and understand its results
- Prepare completed matched measurements, SI or explicitly stated oilfield units, and independent evidence for the selected branch or calibration.
- Enter observedStaticGasContactDepthM, observedProducingGasContactDepthM, knownGasContactAssessmentFlags, following the field table and calculation rules below, then run the tool.
- Read knownSignedConingHeightsM, unknownContactCount. For result objects, inspect the nested output fields below, including any missing evidence or selected indices.
- Correct any input issues and run again. Before using a successful result, review its units, signs, evidence coverage, and stated model or reference assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedStaticGasContactDepthM | Observed static gas contact depth m | list of number | Required |
| observedProducingGasContactDepthM | Observed producing gas contact depth m | list of number | Required |
| knownGasContactAssessmentFlags | Known gas contact assessment flags; binary 1 means assessed and 0 means unknown. | list of number | Required |
Require nonempty aligned nonnegative static and producing depths in metres and binary known flags. For known entries return producing minus static depth, with positive gas height meaning gas moved downward under a downward-positive depth convention. Omit unknown entries from the height list and return their count; the result list no longer has one entry per input row.
heightKnown=producingDepth−staticDepth Read these symbols with the field meanings and branch or reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| knownSignedConingHeightsM | Known signed coning heights m | list of number |
| unknownContactCount | Unknown contact count | number |

}Limitations and assumptions
Measurements, unit conventions, branch identity, and model applicability must be independently established. The result does not infer a complete reservoir or flow model, operational settings, or a reserve classification.
Missing required fields, unknown fields, wrong types, and violated calculation rules return input issues. Numeric values must be finite; nonfinite numeric outputs are rejected. Arrays must be dense, with no missing cells. Numeric lists allow at most 10000 entries, subject to smaller tool-specific bounds above.
Alternative or Complementary methods
For a related task, use Petroleum Water Coning Height Calculator: Coning-height observations compare static and producing fluid-contact depths under a shared datum. This water tool keeps signed observed movement and counts unavailable assessments rather than predicting a contact position. For a complementary step, use Petroleum Coning Critical Rate Water Calculator: Observed water-coning response can be compared with a supplied unwanted-phase criterion across completed rate trials. This tool finds criterion-rate crossings in those records rather than assigning a safe or predictive critical production rate.
