Study Notes
Surface Gathering System
- The text outlines the steps of petroleum production, starting with the wellhead - drilling and completion
- Explains the importance of the wellhead in controlling well pressure and preventing blowouts
- High-pressure formations need wellheads that can withstand up to 20,000 psi
- The wellhead comprises three main parts: casing head, tubing head and the Christmas tree
- Once hydrocarbons are brought to the surface, the main goal is to transport them from the wellhead to the refinery
- The transport system mainly involves Flow lines, which are typically made of carbon steel (for resistance and long laying lengths) or duplex Stainless Steel (for corrosion resistance in harsh environments)
- Flow line fittings include elbows, tee connections, reducers, gaskets, expansion joints and valves.
Oil and Gas Separation
- Separators are crucial for separating liquid (oil, water) and gas components at specific temperatures and pressures, forming the initial processing step in any facility.
- Separators are classified as two-phase (gas separated from liquid) and three-phase (liquid separated into oil and water).
- Separator design considerations depend on factors like gas and liquid flow rates, operating pressures, temperature, and the potential for surging, slugging, density, compressibility, impurities, foam, and corrosion.
Introduction to Sand Production and Detection
- Sand production is a major challenge in oil and gas production, impacting flow rates and well integrity
- Sand particles can bridge, plugging pore spaces and causing a decline in productivity
- Screens are used to prevent sand production by acting as flow filters
- Screen types include wire-wrapped, prepacked, excluder, expandable, and slotted tubular
- Gravel packing, involving the use of specially-sized gravel, is another technique to achieve sand control, creating a more efficient filter than screens alone.
- Internal gravel packs are placed inside the casing, with gravel being pumped into the space between the screen and formation (this also helps with drilling accuracy and efficiency).
- The gravel pack prevents sand movement and ensures effective sand control, reducing the risk of production decline.
