Main Categories of Oilfield Equipment
Tanks
- Bullet Tanks: Designed for the storage of liquids and gases under pressure. Essential for handling volatile substances safely.
- Oilfield & Production Storage Tanks: Standard tanks used for storing crude oil and other fluids. Critical for managing inventory and ensuring a steady supply chain.
- Methanol Spheres: Specialized tanks for storing methanol, which is used to prevent hydrate formation in pipelines.
- Fracturing (Frac) Tanks: Temporary tanks used during hydraulic fracturing to store water, chemicals, or other fluids. They’re often mobile and are used only during the fracking process.
Compressors
- Gas Compressors: Used to compress natural gas for transportation through pipelines or for processing.
- Reciprocating Compressors: Utilize pistons to compress gas. Ideal for high-pressure applications and varying flow rates.
- Screw Compressors: Employ rotary screws to compress gas. Suitable for continuous operation with steady flow demands.
Heaters
- Direct Fired Heaters: Heat fluids directly through combustion. Used for processes requiring immediate and intense heating.
- Indirect Fired Heaters: Transfer heat to fluids without direct flame contact, offering controlled temperature increases and safety in handling flammable materials.
- Line Heaters: Designed to heat fluids in pipelines, line heaters are especially useful for natural gas, helping to prevent freezing or hydrate blockages in colder climates. They work by circulating heated fluids around the pipeline.
Pumps
- Oil Transfer Pumps: Facilitate the movement of oil between storage tanks, processing facilities, and transportation units.
- Pump Jacks: Mechanical devices used to extract oil from wells, especially when reservoir pressure is low.
- Centrifugal Pumps: Widely used in oilfield operations for their ability to handle high volumes of fluid. Centrifugal pumps are efficient for transporting fluids with minimal maintenance and are common in various stages of oil processing.
- Submersible Pumps: Electric submersible pumps (ESPs) are placed directly downhole and are efficient for lifting large volumes of oil, especially from deep wells.
- Progressing Cavity Pumps (PCPs): Known for their versatility, PCPs handle high-viscosity fluids and are often used in heavy oil fields. They work well in applications where there is a mix of oil, gas, and water.
- Reciprocating Pumps: Often used in high-pressure applications, reciprocating pumps are suited for moving viscous fluids and are valuable in injection processes, such as water or chemical injection to enhance oil recovery.
- Diaphragm Pumps: Known for their ability to handle abrasive and corrosive materials, diaphragm pumps are often used in transferring chemical fluids and handling slurry in oilfield operations.
Separators
- Oil/Water Separators: Equipment that separates oil from water in production streams, ensuring compliance with environmental regulations and improving product quality.
- Horizontal Separators: These can be either two-phase or three-phase and are suitable for operations with a high gas-to-oil ratio (GOR). Their horizontal design is advantageous in areas with space constraints and for larger volumes.
- Vertical Separators: Also available in two-phase or three-phase configurations, vertical separators are useful in operations with limited floor space. They are better suited for well streams with lower GOR and are often used in offshore facilities.
Additional Equipment
- Gas Dehydrators: Remove moisture from natural gas to prevent pipeline corrosion and hydrate formation.
- Flare Knockout Drums & Flare Stacks: Safely manage the disposal of excess gases by burning them off.
- Oil Recovery Systems: Enhance the extraction of oil from reservoirs, improving overall yield.
- Drilling Rigs: Essential for drilling new wells to access oil and gas reserves.
Importance of Each Equipment Group
Tanks
- Storage and Safety: Tanks are vital for the safe storage of liquids and gases, managing supply levels, and ensuring smooth operational flow.
- Process Efficiency: Proper storage solutions help in maintaining product quality and operational efficiency.
Compressors
- Pressure Management: Compressors maintain necessary pressure levels for transporting gas through pipelines and for processing needs.
- Operational Continuity: Enable consistent gas flow, which is essential for continuous production operations.
Heaters
- Temperature Control: Ensure fluids are at optimal temperatures for processing, preventing issues like viscosity problems or flow disruptions.
- Safety and Compliance: Proper heating can prevent the formation of hydrates and other safety hazards.
Pumps
- Fluid Movement: Essential for moving oil and other fluids between different stages of production, storage, and transportation.
- Production Enhancement: Pumping units increase extraction efficiency, especially in mature wells.
Separators
- Environmental Protection: Prevent environmental contamination by effectively separating oil from water.
- Product Quality: Ensure that the extracted oil meets quality standards by removing unwanted substances.
