5 Signs Your Well Needs a Production Logging Survey

When production declines or well performance behaves unexpectedly, operators often scramble for quick fixes — adjusting chokes, tweaking chemical programs, or shutting in the well entirely. But without clear data, these moves are just educated guesses. That’s where Production Logging Surveys (PLS) come in. With the right downhole tools, you can accurately diagnose flow profiles, identify issues, and make informed decisions that optimize output and reduce costs.

Here are five common signs that your well may need a production logging survey:

1. Sudden Drop in Production Without Explanation

If your well’s oil, gas, or water rates change sharply — and there’s no obvious mechanical failure or operational change — a production logging run can help pinpoint the issue. Whether it’s a collapsed zone, an unexpected water entry, or a plugged perforation, downhole data tells the real story.

2. Rising Water Cut or GOR

An increase in water cut or gas-oil ratio could signal unwanted fluid migration, crossflow, or coning. Logging tools can confirm where fluids are entering the wellbore, so you can plan targeted shutoff or recompletion strategies.

3. Suspected Channeling or Crossflow Behind Casing

If you suspect that fluids are moving behind pipe — perhaps due to poor cement integrity or a failed plug — production logging tools can detect behind-casing flow and help validate whether remedial cementing or a squeeze job is necessary.

4. Need to Optimize Zonal Contribution in Multi-Zone Completions

In multi-zone or horizontal wells, PLS can help evaluate which zones are producing and how much. With this insight, you can make data-driven decisions about zone isolation, stimulation, or re-perforation to improve overall recovery.

5. Planning an Artificial Lift Upgrade or Reconfiguration

Before changing lift systems or reconfiguring a completion, a production log can give you a baseline of inflow performance. This ensures your upgrade is built on real production behavior — not assumptions.
