Delivering fluid stability, compatibility and performance

Drilling and completion operations rely on fluids that deliver predictable performance across different formations, temperatures, and well designs. Chemistry selection and formulation directly affect rate of penetration, wellbore stability, equivalent circulating density, and the quality of the wellbore handed over to completion and production.

We support drilling fluid and completion system formulators with reliable, fit‑for‑purpose chemistries that help maintain fluid performance and wellbore stability, while integrating smoothly into existing formulations and operational practices.

How we support drilling and completion operations

Our portfolio for drilling and completion applications focuses on functionality, stability, and robustness across a range of fluid systems. To translate these strengths into field performance, our portfolio is built around several key functions that drive reliability and efficiency.

Key functions:

Water-based mud additives
Cellulosic viscosifiers, dispersants, and rheology modifiers that help stabilize water based drilling fluids under high salinity and high temperature conditions. These additives support cuttings transport, fluid loss control, and wellbore integrity while minimizing formation damage and helping operators meet regional environmental requirements.

Oil-based mud additives
Emulsifiers, wetting agents, and related components engineered to build robust, thermally stable oil based mud systems. These chemistries support shale inhibition, lubricity, and emulsion stability in challenging wells, helping maintain fluid performance, protect the wellbore, and reduce non productive time in demanding drilling environments.

Cementing and completion additives
Additives designed to optimize cement and completion fluid performance, including viscosifiers, spacers, and non damaging brine viscosifiers. These chemistries help improve placement and zonal isolation, enhance bonding and well integrity, and support reliable cleanup and flowback, even in high temperature and high salinity environments.

Cleaning agents
Specialty surfactant and solvent blends formulated for efficient removal of oil, residues, and drilling contaminants from equipment, tubulars, and wellbores. These cleaning systems support faster transitions between drilling, completion, and production phases, improve operational cleanliness, and are available in formulations compatible with regional environmental and regulatory standards.

Built for drilling and completion practicality

Across drilling and completion applications, our chemistries are developed with operational practicality and system compatibility in mind:

Emphasis on stable performance across a relevant temperature and salinity range
Focus on compatibility with other drilling and completion additives, as well as formation and completion materials
Alignment with regional and regulatory requirements where applicable, including OSPAR, REACH, and TSCA

This supports more predictable drilling and completion performance and helps provide a better foundation for subsequent stimulation and production operations.
