Oil & Gas Positive Displacement Pumps Reliability
Positive Displacement Pump Reliability & Maintenance maintenance and reliability for Reliability Consulting for Oil & Gas Operations facilities.
Why it matters
Key Benefits
Accurate Chemical Injection Rates
Flow verification on chemical injection pumps confirms that corrosion inhibitor, scale inhibitor, and demulsifier dosing rates match the treatment program requirements that protect downstream process equipment.
Maintained Pipeline Pumping Capacity
Performance monitoring on pipeline reciprocating and triplex pumps ensures pumping capacity keeps pace with production rates without the pressure fluctuations that stress pipeline integrity.
Extended Packing and Valve Life
Valve and packing condition tracking on high-pressure pumps predicts component replacement intervals based on actual wear rates in the specific crude, produced water, or multiphase fluid being handled.
Context
Challenge & Approach
The Reliability Challenge
Oil and gas PD pumps endure high-pressure service with abrasive produced water solids that erode plunger packing, valve seats, and fluid ends. Pulsation from multiplex pumps causes fatigue failures in high-pressure piping and instrument connections. Chemical injection pumps face diaphragm rupture from corrosive treatment chemicals and wellbore pressure spikes. Pipeline custody transfer metering pumps require volumetric accuracy for fiscal measurement compliance. Fluid end cracking on high-pressure injection pumps creates sudden pressure loss and potential hydrocarbon release. API 674 and API 675 standards govern design requirements for these pumps.
Our Approach
We perform fluid end inspection for cracking, erosion, and corrosion at crossbore intersections on high-pressure pumps. Valve condition assessment through pressure rise time analysis and visual inspection identifies erosion and seating defects. Pulsation analysis using dynamic pressure transducers verifies dampener effectiveness and identifies piping resonance. Packing leak rate quantification supports environmental compliance and maintenance scheduling. Our deliverable includes a fluid end inspection schedule per API 674, valve and packing replacement intervals, pulsation management plan, and metering accuracy verification for custody transfer applications.

Learn More →Reciprocating plunger and piston pumps handle high-pressure pipeline boosting, water injection, and well stimulation. Diaphragm pumps provide chemical injection for corrosion inhibitors, scale inhibitors, and methanol hydrate prevention. Progressive cavity pumps transfer viscous crude and high-solids produced water. Gear pumps serve lubrication and fuel transfer applications. Each type requires different monitoring approaches based on its specific failure modes.
Remote wellsite chemical injection pumps require calibration verification against measured chemical consumption rates, stroke counter monitoring to confirm consistent operation between site visits, and diaphragm or check valve condition assessment based on injection pressure trending available through SCADA systems. Establishing expected chemical consumption rates per barrel of production enables remote performance verification from operations centers.
Packing failures on high-pressure reciprocating pumps result from abrasive particles in the pumped fluid scoring the plunger surface, chemical attack on packing materials from H2S, CO2, or treatment chemicals, thermal degradation from friction heat at high stroking rates, and inadequate packing lubrication. Fluid filtration upstream of the pump, proper packing material selection for the fluid chemistry, and plunger surface condition monitoring through leak rate trending are the primary mitigation strategies.
