Study Notes
- Produced water may contain low levels of naturally occurring radioactive materials (NORM).
- Produced water always contains dissolved solids, suspended and dissolved organic materials, formation solids, hydrogen sulfide, carbon dioxide, and chemical additives.
- The primary source of hydrocarbon releases into the ocean is from transportation by tankers.
- Drilling wastes include formation cuttings and drilling fluids.
- Water-based drilling fluids may contain viscosity control agents, density control agents, deflocculants, caustic, corrosion inhibitors, biocides, lubricants, lost circulation materials and formation compatibility agents.
- Waste treatment may include reducing the waste's total volume, lessening its toxicity, or altering its ability to migrate away from its disposal site.
- Waste disposal method depends on the type, composition and regulatory status of the waste.
- The primary disposal methods for solid wastes are to bury them or to spread them over the land surface.
- The base fluid most commonly used in the drilling process is water, followed by oil, air, natural gas, and foam.
- The primary purpose of drilling fluid is to remove the cuttings from the hole and carry them to the surface.
- The various chemicals used during production have a widely varying potential for environmental impact, depending on the chemical and its concentration.
- The most common measure of the potential environmental impact of a material is its toxicity.
- Toxicity occurs when a material causes a deleterious effect on an organism, population, and community.
- The heavy metals encountered in drilling and production activities are related to a variety of environmental concerns, depending on the metal and its concentration.
- The largest volume waste stream in the upstream petroleum industry is produced water.
- The process of removing hydrogen sulfide and carbon dioxide from a gas mixture is called the gas sweetening process.
- Risk assessment consists of four steps: hazard identification, dose-response assessment, exposure assessment, and risk characterization.
