Chevron USA, a subsidiary of Chevron, and Halliburton have introduced a new intelligent hydraulic fracturing technology that utilises a closed-loop, feedback-driven system to enhance the delivery of energy into wellbores in Colorado, US.
This advanced fracturing process integrates automated stage execution with subsurface feedback, eliminating the need for human intervention.
The capability, building upon previous autonomous hydraulic fracturing technology, allows for more precise control over the fracturing process.
By integrating digital automation with real-time subsurface feedback, Chevron and Halliburton have crafted autonomous workflows designed to adjust completion tactics to boost asset performance.
The collaboration has resulted in the fusion of Chevron's hydraulic fracturing and subsurface expertise and Halliburton's ZEUS IQ intelligent fracturing platform.
This platform includes OCTIV auto frac and Sensori monitoring systems, which are essential for the feedback loop and control capabilities required for intelligent completions.
Halliburton Production Enhancement vice-president Shawn Stasiuk said: “We drive innovation in the digital space. We built the digital environment down to the field level and enable our customers to test their best ideas.”
Chevron's advancements in closed-loop automation are advancing hydraulic fracturing, particularly in shale and tight rock formations.
This approach enables operations to respond dynamically to localised conditions in real time, moving away from the traditional method of performance forecasting.
Chevron Rockies Business Unit vice-president Kim McHugh said: “At Chevron, we focus on continuously advancing asset performance safely through the innovation of our subject matter experts, new technology and strategic collaborations.
“This real-time adaptive feedback loop is expected to further drive efficiencies and improve overall asset performance.”
Recently, Chevron has shown interest in expanding its global footprint. According to Djoko Siswanto, chairman of Indonesia's upstream oil and gas regulator SKK Migas, the company is exploring opportunities to develop oil and gas assets in Indonesia.
