Definitions

  • the present invention generally relates to methods and compositions for corrosion inhibition for use in the oil and gas exploration, recovery, and processing industries. More specifically, the invention relates to methods of producing corrosion inhibitor compositions by applying urine to a water source and methods of inhibiting corrosion by contacting a corrosion inhibitor comprising urine to metal containment.
  • Aqueous liquids are injected into the earth and/or recovered from the earth during subterranean hydrocarbon recovery processes such as hydraulic fracturing (tracking) and tertiary oil recovery.
  • an aqueous liquid called an "injectate” is injected into a subterranean formation. Injectates include water and entrained solids and/or solvents therein.
  • a water source called "produced water” is recovered, i.e. flows back from the subterranean formation and is collected.
  • Produced water includes one or more of injectate, connate (native water present in the subterranean formation along with the hydrocarbon), sea water, and minor ( ⁇ 5 wt.%) amounts of hydrocarbon products, which are hydrocarbon liquids or solids entrained (dispersed, emulsified, or dissolved) in the produced water.
  • one or more of the injectate and the produced water includes "corrodents” such as salts and/or other dissolved solids, liquids, or gasses that cause, accelerate, or promote corrosion of metal containments such as metal pipelines used to transport the water sources toward, into, out of, or away from a subterranean formation, metal tanks used to hold the water sources for a period of time, and/or other metal equipment that contacts the water sources before, during, or after injection or production.
  • corrodents are hydrogen sulfide, carbon dioxide, oxygen, sodium chloride, calcium chloride, and/or sulfur dioxide.
  • a blend of two or more corrosion inhibitors is deployed, for example as components of a mixture designed for a particular hydrocarbon recovery process.
  • the one or more corrosion inhibitors are added to an injectate and/or produced water along with additives such as polymers, surfactants, scale inhibitors, paraffin inhibitors, metal complexing agents, and the like.
  • Such corrosion inhibitors are beneficial in that they permit the use of carbon steel components rather than the much more expensive high nickel, cobalt, and chromium alloys or other materials either more expensive than carbon steel and/or which inherently entail other disadvantages in suitability for the purpose of liquid containment.
  • Corrosion inhibitors are added to the liquids and dissolved gasses which come into contact with metal surfaces and such inhibitors prevent, retard, delay, reverse, and/or otherwise inhibit the corrosion of metal surfaces such as carbon-steel metal surfaces. While highly desirable for this purpose, their use entails additional cost for the operator.
  • produced water is reused as injectate. If such injectate contains corrosion inhibitor, some of the corrosion inhibitor remains in the ground, some is returned as part of the produced water, or both.
  • Some synthetic chemicals used as corrosion inhibitors have further disadvantages such as toxicity or deleterious environmental effects. If such corrosion inhibitors are injected and can remain in the ground, it is advantageous to minimize pollution by using a corrosion inhibitor with low toxicity to humans and or other fauna or flora. It is a further advantage if the corrosion inhibitor is biodegradable. It is a further advantage if corrosion inhibitor compositions comprising a corrosion inhibitor can be discharged into an existing sewer system without special means being employed at the sewer to remove or treat the corrosion inhibitor. Therefore there is a need for a relatively low-cost, biodegradable corrosion inhibitor of low toxicity which can readily be obtained in large amounts inexpensively and can be discharged into the sewerage system where it can be processed with normal available means.
