REVIEWED P2 OPTIONS
for the
Oil and Gas - Drilling Rig Operations Process

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

Following are a list of options that have been reviewed by pollution prevention specialists. These options have worked at other facilities and may work at yours.

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

Contain spilled fuel

Use specific drilling cuttings

• Minimize drilling hole size when possible.
• Design and monitor drilling mud activities to minimize caving.

Sustitute 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 lead free pipe dope

Use durable drill bits.

Manage surplus casing

Manage cement/grout

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

Treat produce water with polymers

Reuse drums and containers

Substitute solvents to clean equipment

Reuse collected cleaning solvent

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

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

Use high pressure hose nozzles for rigwash

Manage paint purchases

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
