Following are a set of P2 options you may wish to implement. No option is perfect for everyone, but sometimes options that have worked at one facility can work at yours. They might also serve as inspiration.

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.
