Tetra Technologies launches reduced-zinc deepwater completion fluid

Tetra Technologies, Inc. (NYSE: TTI) announced the introduction of TETRA Neptune Z-Lite, a high-density completion fluid designed for deepwater and high-pressure well applications, according to a company press release.

The fluid uses the company's patented Neptune fluid chemistry and is available in densities up to 17.5 pounds per gallon. Tetra Technologies states the product offers up to 60% lower zinc-ion concentration compared to conventional zinc-based fluids while maintaining required density performance. The fluid is described as thermally stable, solids-free, and compatible with most elastomers and formation fluids, and can be recycled using standard field equipment.

Tetra Technologies said it has been awarded a three-well program using TETRA Neptune Z-Lite for Beacon Offshore Energy's Shenandoah and Monument projects in the Gulf of America, with an expected start in 2026. The wells are rated for 20,000 psi.

"By applying our patented TETRA Neptune and our high-purity zinc bromide chemistries, we are leveraging the advantages of both," said Brady Murphy, president and chief executive officer of Tetra Technologies. "The Neptune chemistry improves corrosion performance while lowering zinc concentration, thereby reducing handling requirements across the wellsite, production facilities, and refineries."
