  "term": "Diagenesis",
  "field": "Oil and gas",
  "definition": "The collective physical, chemical, and biological changes that occur in sedimentary rocks after deposition and before metamorphism. These processes include compaction, cementation, dissolution, and recrystallization, altering the original sediment into a lithified rock. Diagenesis influences reservoir quality by modifying porosity and permeability, which affects fluid flow and hydrocarbon accumulation.",
