STEP-conneCT vs. Surface Gauges: Real-Time Data Delivers 42-Hour Time Savings and Zero Tool Trips on Duvernay Pad

Challenges

• Trial three wells with STEP-conneCT real-time data verse three wells with conventional surface gauge monitoring

Results

Wells using STEP-conneCT averaged:

• 28% less hours in-hole per well
• 32% reduction in transition times between plugs
• 20% reduction in treatment time per plug
• 42 less hours on location compared to conventional methods
• Zero tool trips

A valued client in the Duvernay had a six-well pad to be milled. All wells had identical reservoir conditions, wellbore depths, and plug types. The client aimed to optimize their milling campaign using STEP-conneCT for real-time downhole data and analytics.

The operator believed this would enhance efficiencies and decision-making compared to relying on traditional surface gauges, which provided subjective data, leading to uncertainty and inefficiencies. By trialing this new technology, the operator sought to confirm that consistent operating parameters based on objective measurements reduces in-hole time and prevents unnecessary trips, significantly improving efficiencies and lowering costs.

To evaluate this, three wells used conventional surface gauges to monitor milling, while the remaining three wells utilized STEP-conneCT. Performance was measured by time in-hole and average milling costs for each well, excluding overall completion costs.

The wells using STEP-conneCT averaged 14 fewer hours in-hole per well. This time savings resulted from a better understanding of wellbore conditions, which led to optimized milling performance and the elimination of unnecessary wiper trips. The technology minimized stoppage time, allowing the milling assembly to operate at peak efficiency while reducing stalling events common in conventional milling.

The 14-hour reduction in time per well translated to 42 fewer hours on location compared to conventional methods, also shortening the total pad-to-production time and decreasing the client's cumulative burn rate. STEP-conneCT significantly improved efficiencies and reduced costs compared to conventional milling techniques reflected in Table 1.
