Drilling Background

Overview of Drilling Wastes

Waste Management Hierarchy

Waste Management Strategy

Barriers of Waste Management

Opportunities of Sound Waste Management

Conclusion

Q&A Session

As per US EIA , World Energy demand is

increasing.

Drilling operations are expanding to produce

required quantity of crude oil.

Drilling waste management is playing a critical

role for successful drilling and production.

Proper application of waste management

principles are required

Recycling/ Reuse

Source Reduction

Drilling Practices which Minimize Generation of

Drilling Wastes

Directional Drilling

Drilling Smaller Diameter Holes

Drilling Techniques that use Less Drilling Fluid

Using Muds and Additives with Lower

Environmental Impacts

Synthetic-based Muds

New Drilling Fluid Systems

Alternate Weighting Agents

Recycling:

The reprocessing of waste into the same or a

different product.

Ex: Separation of Drilling cuttings from the OBM.

Reuse:

The reuse of a material on more than one

occasion.

Ex: Reusing of OBM after separation of drilling

cuttings from it.

Thermal Incineration

Thermal Desorption (Direct & Indirect)

Bioremediation

Vermiculture

Stabilization and use as a construction material

Solvent Extraction using Super Critical CO2

Onsite burial (Pits, Landfils)

Discharge to Ocean

Commercial disposal facilities

Slurry Injection
