#### **What normal pressure trends can miss**

See how evoleap identified a developing wax restriction in an offshore flowline while measured pressure drop and production rate remained within their normal historical variation, and how the team checked the response to a chemical adjustment.

 

#### **When the measurements look familiar, the system may still be changing**

Changing production rates and operating conditions can make a developing flowline restriction difficult to distinguish from normal variation.

 

This five-page case study explains how evoleap compared field measurements with calibrated multiphase-model expectations to investigate a discrepancy that raw trends had not made obvious.

 

For the operator, the question was practical: was the line genuinely changing, and could an in-service response still work?

 

#### **Inside the case study**

- **The signal behind the raw trends:** How the Performance Index revealed a mismatch while measured pressure drop and production rate remained within their historical scatter.
- **The investigation and response:** The team’s sequence of testing credible alternatives, increasing wax-dispersant injection, and checking what happened afterward.
- **Why configuration matters:** How limited remediation options and a third-party host affect the choices available when a restriction develops.
- **The consequences of escalation:** An illustrative response ladder showing how intervention methods, planning costs, and production disruption can differ.

#### **What the team observed**

The case reports that wax-dispersant injection was doubled, the Performance Index returned to its normal range, and wax arrived at the production platform. Together, those observations supported the team’s diagnosis and assessment of the response.
