Oil and Gas Well Site Equipment Overview

Introduction

• Focus on the function of equipment in an oil and gas well site.

Rod Pump

• Positioned in the well bore.
• Brings oil, water, and gas (emulsion) to the surface through flowline tubing.

Two-Phase Vertical Separator

• First vessel for the emulsion.
• Separates gas from oil-water emulsion.
  • Gas rises to the top, flows out through an outlet.

Kimray Back Pressure Regulator

• Maintains constant pressure in the separator to move liquids.
• Gas exceeding set point is sent to the meter run.
  • Meter run measures, records, and sells gas to midstream companies.

Flare Valve

• Used during maintenance on the sales line or when pressure builds.
• Opens at a higher set point than the sales valve, sending gas to a combustor or flare.

Liquid Level Control in Separator

• Emulsion collects at the bottom of the vertical separator.
• Controlled by a liquid level controller (float ball + dump valve).
  • Opens when fluid rises, allowing oil, water, and solids to flow out.

Heater Treater

• Further processes the emulsion after the separator.
• Emulsion enters through the inlet and hits a baffle; gas begins to separate.

Gas Management

• Gas flows out to sales or flare valves.

Separation Process

• Emulsion funneled downcomer pipe to the bottom of the vessel.
• Heat from the fire tube allows oil and water to separate.
  • Oil floats on top of water.
• Oil outlet pipe leads to a kimray weight-operated dump valve.
  • Valve opens to send oil to storage tank for midstream purchase and transport.

Produced Water and Salt Water Management

• Saltwater is produced, controlled by a water siphon.
  • Flows through a siphon box and down to another weight-operated dump valve.
• Water goes to storage tank or water treatment plant.

Recirculation

• A recirculating line sends water back into the treater for further processing.

Summary

• Pipelines on location include bypass lines for various vessels.
• Goal: Transform raw products into usable and profitable resources.
