Using Neptune Chemistry to Achieve Required Density With Lower Zinc Content; Awarded Three-Well 20k psi Deepwater Project in the Gulf of America With Estimated Start in 2026

SPRING, Texas, June 29, 2026 /PRNewswire/ -- TETRA Technologies, Inc. (NYSE:TTI) today announced the introduction of TETRA Neptune Z-Lite, a high-density completion fluid designed for deepwater and high-pressure well applications. The fluid system uses our patented Neptune fluid chemistry and expands the Company's completion fluids portfolio by offering up to 60% lower zinc-ion concentration than conventional zinc-based fluids while maintaining required density performance. TETRA has been awarded a three-well program for TETRA Neptune Z-Lite for Beacon Offshore Energy's Gulf of America Shenandoah and Monument projects expected to begin in 2026.

TETRA Neptune Z-Lite reduces zinc-ion concentration, helping limit zinc returns from the wellbore and reduce refinery exposure. Available in densities up to 17.5 ppg, TETRA Neptune Z-Lite is thermally stable, solids-free, and designed to offer lower corrosion potential than conventional zinc brines. The fluid is compatible with most elastomers and formation fluids and can be recycled using standard field equipment.
