Reviewed Oil and Gas - Well Completion Options
Options below have reviewed by pollution prevention specialists. They are commonly recommended and implemented
for facilities. |
|
Prevent paraffin formation |
- Install magnetic fluid conditioner to prevent paraffin formation
- Use paraffin inhibitor chemicals.
- Use hot-oil treatment to dissolve paraffin in well and flow lines.
|
|
Reduce lubricating oil |
- Test oil and extend its use based on wear versus accumulated operating hours. [Note: Many lubricating oil suppliers offer testing service at no charge.]
- Recycle in-process whenever possible.
|
|
Minimize Produced Water |
- Use a closed-loop drilling fluid system.
- Drill horizontal wells to minimize water production.
- Optimize production rate to minimize the influx of water.
- Treat the producing formation with polymers that decrease the permeability of water, while maintaining the permeability of hydrocarbons.
- Hydro-test pipelines, equipment, and tanks with produced water.
|
|
Reduce treating chemicals |
- Control inventory by accurately estimating amounts required, or purchasing smaller quantities only as required.
- Offer to give to or exchange unused chemicals with other facilities in lieu of recycling, treatment, or disposal.
- Use non-hazardous products.
- Store and maintain chemicals properly to prevent spills or leaks.
|
|
Minimize sand production |
- Optimize production rate to minimize sand production.
- Use uncontaminated sand as fill material.
|
|
Reduce and recycle slop oil |
- Recycle back into production stream.
- Replace impeller-type pumps used for fluid transfer service with canned submersible pumps to eliminate leaks from impeller pumps seals and gear boxes.
- Send slop oil that cannot be recycled into production to a state-permitted tank bottoms reclamation facility.
|
|
Reduce scale |
- Use scale inhibitors.
- Avoid mixing incompatible produced waters, which results in scale formation.
|
|
Manage lubricating oil filters |
- Change filters only when necessary.
- Use reusable filters.
- When handling filters, take precautions to prevent oil spillage.
- Isolate all drained fluids in re-sealable container for in-process recycling.
|
|
Remove Pit Liner |
- Remove waste and liner for proper disposal.
- Remove oil and salt-laden mud, fold in and close with liner in place.
