wellbore cleanout & Completion fluids

Whereas aqueous drilling fluids circulated out of the wellbore normally disperse and blend into the environment, NADFs need assistance.  The oil sticking to solid drill cuttings that can't be recovered must ultimately be degraded by microorganisms. This process is slow, but can be sped up by using more biodegradable base oils, and by improving bacteria and contacting processes.

industrial cleaning & degreasing

When drilling with NADFs, the wellbore surface becomes oil-wet. Better wellbore cleanout fluid chemistries will prevent damaging interfaces from forming between NADFs and cement, and between NADFs and brine completion fluids. These systems should be non-hazardous to workers and eco-friendly.

Consulting

 

There is a dual benefit from having more efficient, eco-friendly, and cost-effective chemistries for cleaning oil from the wellbore and drill cuttings.  These same base fluids, solvents, surfactants, and microbes can be used at the surface to clean up tanks, pits, and oil spills.

Bio

Don Van Slyke 

An industry-leading expert in drilling fluid base oils, Don worked for Chevron and Unocal for 34 years. He invented and led the development of Saraline, one of the most commercially successful drilling fluid base oil products in the oil & gas industry.  It has been used on the lower (most critical) sections of over 5,000 wells drilled during the past 20 years.

"Don demonstrates mastery of the fundamental knowledge of drilling engineering and drilling fluids chemistry, the capability to communicate clearly and the ability to use common sense in solving problems"


"Don had a huge impact on Chevron and Unocal's drilling performance worldwide allowing them to use environmentally friendly affordable fluids that had a great drilling performance"

SERVICES

The superior drilling performance of non-aqueous drilling fluids (NADFs) is unchallenged. Yet in many cases operators are not using the best available NADFs  when health, safety and the environment are considered in addition to cost. Improved drill-in fluids are needed to reduce formation damage and access increasingly pressure-depleted reservoirs.
