¹ Compared with diesel-based drilling fluid. Data from multiple field trials and based on a 10,000-ft lateral, US$50,000/d rig operation (including peripherals) and GTL fluid (Neoflo 4633) at US$23/bbl more than diesel. The savings are specific to the calculation date and site. These calculations may vary from site to site and from time to time, depending on, for example, the application, the operating conditions, and current drilling fluid being used.

Our GTL Drilling Fluids products

GTL Drilling Fluids FAQs

What are Shell GTL Drilling Fluids and how are they produced?

Shell GTL Drilling Fluids are high-purity synthetic base fluids made from natural gas using our advanced Gas-to-Liquids (GTL) technology. This process delivers consistent, innovative fluids that help operators drill with confidence, even in the most challenging operating environments.

What are the benefits of using GTL Saraline 185V or Neoflo 4633 over diesel-based drilling fluids?

Shell GTL fluids offer a step-change in performance and sustainability. They are low in skin or eye toxicity, readily biodegradable according to OECD 301B/301F (<60% biodegradation after 28 days), and deliver excellent thermal stability. Operators benefit from safer handling and improved operational efficiency.

Are Shell GTL Drilling Fluids biodegradable?

Yes. Our GTL fluids meet stringent regulatory requirements, including OSPAR and REACH. They are classified as having low aquatic toxicity in accordance with OECD test guidelines 201, 202, and 210 and readily biodegradable according to OECD 301B/301F.

In which operating environments can Shell GTL Drilling Fluids be used?

From arctic cold to desert heat, Shell GTL fluids are built to perform. Their low pour point and high flash point make them ideal for deepwater, high-pressure, and high-temperature wells‚ where reliability is non-negotiable.

What is the difference between Saraline 185V and Neoflo 4633?

Both are GTL-based fluids, but Saraline 185V is optimized for global offshore use, while Neoflo 4633 is tailored for North American operations. Each offers Shell's signature performance, with region-specific formulations.

What kind of performance improvements can operators expect?

Operators using Shell GTL fluids report faster rates of penetration, better mud stability, and reduced downtime than diesel or middle distillates. These fluids are engineered to help teams drill smarter, safer, and more efficiently.

Where can I find technical and safety datasheets for GTL Drilling Fluids?

You can download Technical Data Sheets (TDS) and Safety Data Sheets (SDS) directly from this Shell GTL Drilling Fluids webpage. The following documents provide detailed specifications to support safe and effective use. See for more information also the Products section of this page.
