We develop and supply chemicals used for the cleaning of drilling mud, the treatment of oil drilling waste, refinery waste, oil sludge and the recovery of oil from waste. We also supply our products for wellbore solutions such as casing cleaning and filtercake removal and Enhanced Oil Recovery. 

We are based in Scotland, just outside Edinburgh, in Livingston. We supply our products from our manufacturing sites in Scotland (where we have two manufacturing locations) and from our manufacturing site in Houston, Texas. 

We don't just supply chemicals though. We are different in our understanding of waste treatment processes and the need for our chemistry to fit in with your process, your needs and the goals you have to achieve. How our products fit in with your work and help you achieve your goals, that is where we work with you. Like we work with all our customers. 

Active globally, SAS has supplied its products around the world since 2000. Founded in Edinburgh, Scotland by John Harrison and myself, Mark Zwinderman, the company gradually earned its place in the oilfield world with its unique microemulsion chemistry. Equally, if not more, important is the approach to problem solving we at SAS have worked on for many years. 

It is not about being a solutions provider or using buzzwords. It is all about efficiently understanding the nature of the waste, the process to be used and the desired outcome. Our focus on those elements has resulted in a fast growing and loyal customer base. 

SAS was started with the clear goal of delivering the best solutions to oil waste problems. Best meaning the best environmental solutions, the best solutions for health & safety and the best economically.

Removing oil based drilling mud from mud pits, tanks or supply vessels can be a tough task with caked mud stubbornly resisting efforts to be removed. Mobilizing the mud and getting out of the pit without plugging lines and pumps and taking days is common. Delays in cleaning the pits and tanks are expensive, tie up teams that could be on to their next job. 

The SAS PitClean, SAS MudClean and SAS MudClean HD simply make the problems go away. Whether you are offshore or onshore. It doesn't matter if the mud is high weight, low weight, synthetic based or diesel based. Our products get diluted in sea water, fresh water or dirty water and clean mud residues quickly, without fuss. Every time. Leaving behind a clean surface and a mud slurry that can be easily pumped from the pit. 

Following the cleaning, SAS PitClean, MudClean and MudClean HD go to work by splitting the collected waste effluent. Valuable oil based mud and solids separate out under gravity, and the wash fluid is reclaimed and reused. SAS products generate up to 80% less hazardous waste compared to water only methods or approaches using diesel plus detergent. 

SAS products have been used to clean over 1000 mud pits around the world since 2002 by oil service companies looking to provide greater value to their clients by reducing cleaning times, and getting operations back online faster with less risk to personnel and the environment. 

In addition to SAS PitClean™ for offshore operations, SAS Ltd provides mud pit cleaning products designed specifically for use onshore applications. These products deliver every time for our customers. They can deliver for you and your team as well. Make your life easier, get jobs done faster and cut back on drilling waste.
