Cost Analysis

GAMMA RAY (API) Gamma Ray measures natural radioactivity in formations. Higher values typically indicate shales, while lower values indicate clean sandstones or carbonates.

SONIC (μs/ft) Sonic logs measure the time it takes for sound waves to travel through formations. Higher values indicate slower velocities, typically in less dense or more porous rocks.

TENSION (lbs) Cable tension is critical for tool safety. Higher values when pulling up, lower when going down. Sudden changes may indicate tool sticking or other issues.

TEMPERATURE (°F) Downhole temperature increases with depth. Important for tool calibration and identifying thermal anomalies in the wellbore.

Formation Analysis

Interpretation

Based on log responses, the following formations have been identified:

  • 0-30 ft: Sandstone (Low GR, Medium Sonic)
  • 30-60 ft: Shale (High GR, High Sonic)
  • 60-90 ft: Limestone (Low GR, Low Sonic)
  • 90-120 ft: Coal (Very Low GR, High Sonic)
  • 120-150 ft: Dolomite (Medium GR, Medium Sonic)

Cost Breakdown

? Sandstone: Typically porous, permeable reservoir rock. Low gamma ray, medium sonic response.
? Shale: Fine-grained, clay-rich rock. High gamma ray due to radioactive elements, high sonic (slow velocity).
? Limestone: Carbonate rock, can be reservoir or seal. Low gamma ray, low sonic (fast velocity).
? Coal: Organic-rich rock. Very low gamma ray, very high sonic (very slow velocity).
? Dolomite: Magnesium-rich carbonate. Medium gamma ray, medium sonic velocity.
