High-performance sandstone stimulation solution
Stimulate oil production with a single-stage system that removes scale, drilling fluids, clays, and other damage.
Efficient, low-risk sandstone stimulation solution
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.
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.
Lower corrosion, low precipitation damage, and low fluid incompatibility risks while increasing production
More uniform stimulation across long zones with full reservoir coverage
Lower emissions from reduced handling, operational time, and volume required
Improved HSE from reduced disposal volumes and personnel exposure
Reduced mixing time and flexibility to bullhead or pump through coiled tubing
Higher ROI, lower cost per additional bbl produced, and low-capex requirements for intervention
