Tip the Scales
in Your Favor
You might think that you can’t get high performance from water-based
fluids, that they negatively impact your well economics, or that
there really isn’t a well-developed, balanced approach between
performance, sustainability, and economics.
Well, M-I SWACO has developed one of the most complete portfolios
of aqueous fluid solutions that not only deliver sustainability but
competitive performance in drilling and drill-in reservoir drilling fluids
and also include advanced digital management and automation.
Aqueous fluid solutions—water-based drilling fluids that are more
than just water.
