Salt Water Disposal
Each disposal well facility has a unique set of challenges based on its specific combination of surface equipment design, well design, geology, and fluid compatibility issues as a result of the variable types and quantities of wastewater that are brought into the facility.
However, all disposal wells share four common operational objectives:
- Maximize the volume that the facility can process and that can be injected into the well every day
- Recover as much skim oil as possible
- Minimize damage and maximize the potential capacity of the reservoir
- Minimize OpEx and R&M costs on the surface
The chemical program at an SWD facility plays an important role in achieving each objective; but frequently, the objectives must be prioritized due to the fact that the best chemistry to achieve one objective may not be the best chemistry to achieve one of the other objectives. In all scenarios, reactive chemical programs, wherein the chemicals and dosages are determined only after there is a failure in one of the objectives, cost more money and fail to consider the law of unintended consequences on the rest of the facility and objectives.
