Multi-Use, High-Density Fluid Systems in the North Sea

When it comes to drilling and completing hydrocarbon wells, one way to maximise asset value and return on investment is to work more efficiently and simplify the toolkit. This can often be achieved by using one product as the reservoir drill-in fluid, the completion fluid, the barrier fluid, and the packer fluid, as well as in the composition of slugs and the brine phase of nonaqueous fluids.

This article examines high-density fluid systems and their advantages, such as their protection of reservoirs, ability to be customised for use in different applications, their low cost compared to formates, and low carbon footprint.
