OneSTEP Family single-stage sandstone stimulation solutions.

OneSTEP EF

Efficient, low-risk sandstone stimulation solution

A breakthrough in sandstone acidizing

The innovative OneSTEP EF efficient, low-risk sandstone stimulation solution is suitable for use in conventional injectors and producer sandstone reservoirs with varying mineralogy complexities. It reduces risk of precipitates forming by eliminating the challenges usually faced from poor and uneven flow in heterogenous reservoirs.

By combining multiple conventional stages in one optimized stage, OneSTEP EF solution enables reducing total fluid volume by more than 40%. This translates to lower pump times and increased operating efficiency and safety. Flowback efficiency is improved particularly in gas wells where minimizing injected fluid promotes better production performance. Compared with chelants, this technology will also provide improved cost efficiency and performance in low-temperature applications.

OneSTEP EF efficient, low-risk sandstone stimulation solution recognized as a World Oil finalist for the Best Oilfield Fluids and Chemicals Award

OneSTEP EF solution was recognized as a finalist for the 2022 World Oil Best Oilfield Fluids and Chemicals Award.

Single-Stage Sandstone Acidizing Fluid Demonstration

20,000-ppm calcium chloride solution is added to organic mud acid vs. OneSTEP EF solution.

Single-stage sandstone acidizing fluid demonstration

In this video demonstration, 20,000-ppm calcium chloride solution is added to both organic mud acid (OMA) and OneSTEP EF solution. This is as a proxy to show the effect of residual calcium ions commonly in the matrix during an acidizing job. OneSTEP EF solution enables single-stage acidizing, combining multiple conventional stages into one. It offers a lower risk of emulsion, sludge, and damaging precipitations often caused by conventional acidizing methods such as OMA.
