Reviewed Oil and Gas - Drilling Rig Operations Options
Options below have reviewed by pollution prevention specialists. They are commonly recommended and implemented
for facilities. |
| |
| Test lubricating oil to extend use |
- Test oil and extend its use based on wear versus accumulated operating hours [Note: Some oil suppliers offer free testing.]
- Recycle in-process whenever possible.
|
| |
| Incorporate good housekeeping |
| Incorporate good housekeeping to prevent spills.
|
| |
| Contain spilled fuel |
| Contain spill as soon as possible.
|
| |
| Use specific drilling cuttings |
- Minimize drilling hole size when possible.
- Design and monitor drilling mud activities to minimize caving.
|
| |
| Sustitute oil-based drill cuttings |
| Substitute organic additives, polymers, or biodegradable additives for oil-based mud to reduce costs associated with cleanup of oil-based drill cuttings.
|
| |
| Use alternative mud and additives |
- Use a closed-loop mud system.
- Use the reserve pit management system. Optimize solids control.
- Use low solids, non-dispersed muds.
- Use unused additives at other sites.
|
| |
| Manage mud and additives |
- Control inventory (accurately estimate amounts required and purchase only as needed), and plan ahead to avoid unused materials.
- Use unused additives at other sites.
|
| |
| Use wiping tool |
| Use and inside diameter wiping tool for drill pipe.
|
| |
| Use lead free pipe dope |
| Choose biodegradable, lead free pipe dope.
Purchase only what is needed.
|
| |
| Use durable drill bits. |
| Purchase highly durable drill bits.
|
| |
| Manage surplus casing |
| For surplus casing, purchase and use only what is needed.
Use surplus at other sites.
|
| |
| Manage cement/grout |
| Purchase and use only what is needed. Use any surplus cement for erosion prevention.
Then return any unused dry cement to vendor.
|
| |
| Minimize water production |
- Use a closed-loop drilling fluid system.
- Drill horizontal wells to minimize water production.
- Optimize production rate to minimize the influx of water.
|
| |
| Use produced water to test equipment |
| Hydro-test pipelines, equipment, and tanks with produced water.
|
| |
| Treat produce water with polymers |
| Treat the producing formation with polymers that decrease the permeability of water, while maintaining the permeability of hydrocarbons.
|
| |
| Reuse drums and containers |
| Reuse drums and containers, clean (triple rinse) first only if necessary.
|
| |
| Substitute solvents to clean equipment |
| Substitute non-hazardous biodegradable surfactants (soap) for hazardous solvents (mineral spirits) to clean equipment.
|
| |
| Reuse collected cleaning solvent |
| Use drip pans to collect solvent for reuse (use dirty solvent for initial cleaning and clean solvent for final cleaning, if necessary). |
| |
| Minimize cleaning rags |
- Maintain equipment and facilities so that cleanup with rags is minimized.
- Segregate from other waste, and wash for reuse.
|
| |
| Store and maintain chemicals properly |
| Store and maintain chemicals properly to prevent spills or leaks. |
| |
| Surplus chemicals management |
- Control inventory by accurately estimating amounts required, or purchasing smaller quantities only as needed.
- Offer (or exchange) unused chemicals to other facilities in lieu of recycling, treatment, or disposal.
- Use non-hazardous products.
|
| |
| Reuse rigwash water |
| Remove paint solids from water and reuse.
|
| |
| Use high pressure hose nozzles for rigwash |
| Use low-volume, high pressure hose nozzles with automatic cutoffs.
|
| |
| Manage paint purchases |
| Purchase only the required amount and use it all before it becomes unusable.
|
| |
| Paint only when and where necessary |
- Size the paint batch according to the specific job.
- Purchase highly durable paints.
- Control and reduce over-spray.
|
| |
| Reduce sandblast media |
- Use paints that do not require sandblasting.
- Use as aggregate in road mix, if allowable.
|
| |
| Manage litter and debris |
| Rent rollaway trash trailer at drill site. Dispose of trash as needed.
