Publisher Summary This chapter discusses the Regulatory Compendium, including the collection and organization of the pertinent information, and the findings and trends relative to the regulations and practices governing slurry injection in the United States. The Regulatory Compendium provides a comprehensive compilation of the regulatory approaches to injection processes used to dispose of drilling wastes, particularly slurry injection. The regulation of slurry injection and other injection technologies varies greatly by state. Independent of regulatory considerations, slurry injection may not be the preferred option of most practicing independent oil and gas operators, because of the costs involved in reconstituting the drill cuttings into a true slurry texture. Other, less expensive injection technologies, including one-time-event subfracture injection and annular injection of drilling pit fluids, seem more favored. Moreover, these practices appear more appealing to the regulatory agencies. Proper design and management of annular injection are critical to ensure that the fluids are contained in the receiving zone. |
