DeepSTIM
Deepwater stimulation vessels
Overview
Stimulate the toughest deepwater wells with integrated offshore execution and real-time collaboration
DeepSTIM™ stimulation vessels are designed for endurance and efficiency in some of the world’s most hostile offshore environments, including the South Atlantic Ocean, the Indian Ocean, the North Sea, and the deepwater Gulf of Mexico.
Each high-capacity vessel delivers a full range of deepwater well services, including:
- Matrix acidizing
- Acid fracturing
- Proppant fracturing
- Sand control
- Scale control
Through onboard integration of the InterAct™ global connectivity, collaboration, and information service, DeepSTIM vessels enable real-time data transmission and seamless collaboration between offshore and onshore teams—enhancing decision-making and treatment execution anywhere in the world.

How it works
Integrated offshore execution from blending to pumping
DeepSTIM vessels integrate storage, blending, and pumping systems directly onboard to execute stimulation treatments offshore. Fluids and proppant are prepared on the vessel using automated mixing systems, then delivered at the required rates and pressures through high-capacity pumping equipment. Throughout the operation, treatment parameters are monitored and adjusted to ensure consistent execution and treatment quality.
FAQs
What types of stimulation treatments can DeepSTIM vessels perform?
DeepSTIM vessels support fracturing, acidizing, sand control, scale control, and energized fluid treatments in offshore environments.
What makes DeepSTIM vessels suitable for deepwater operations?
They are designed for harsh offshore environments with high-capacity pumping systems, onboard storage, and integrated blending capabilities that support complex, long-duration operations.
How do DeepSTIM vessels support operational efficiency offshore?
By integrating pumping, blending, storage, and logistics on a single vessel, DeepSTIM reduces the need for additional equipment and streamlines offshore execution.
