Ann: EP 98 Operational Update - SS-3H drilled to TD in 25 days, page-26

Given likelihood of heavy rain kicking in at some point soon - perhaps 10 days from here - what do you make of this @SmallFish991?

Organizing a frac fleet for two wells on the same pad—a 1000m horizontal and a 3000m horizontal, both 3000m deep—requires precise planning to ensure efficient operations, minimize weather risks, and optimize the use of the 32 pump and auxiliary trucks. Here’s a structured plan:

1. Assess the Requirements

Well-Specific Considerations:

•1000m Horizontal Well:

•Likely requires lower frac intensity (fewer stages, lower water and proppant volumes).

•Estimated total fluid volume: 10,000-20,000 m³.

•Estimated proppant volume: 1,000-2,000 tons.

•3000m Horizontal Well:

•Requires higher frac intensity (more stages, higher water and proppant volumes).

•Estimated total fluid volume: 30,000-60,000 m³.

•Estimated proppant volume: 3,000-6,000 tons.

Fleet Capabilities:

•32 Pump Trucks: Capable of handling high pumping rates (10-14 m³/min per truck).

•Auxiliary Trucks: Includes blenders, sand silos, water storage, chemical units, and data vans.

Operational Timeframe:

•Rain Expected in 10 Days: This imposes a deadline. Frac operations must either finish before the rain or be staged to ensure critical work is completed before adverse weather affects logistics or safety.

2. Optimize Fleet and Equipment Allocation

Stage Configuration:

1.Assign 20 pump trucks to the 3000m well:

•Focus the majority of resources here due to its larger size and higher demands.

•Utilize higher pumping rates (e.g., 14 m³/min) for larger fluid volumes and stage efficiency.

2.Assign 12 pump trucks to the 1000m well:

•Use fewer trucks due to its smaller size and lower requirements.

•Pump at 10-12 m³/min to match the reduced stage intensity.

Auxiliary Equipment Allocation:

•Sand Handling: Position sand silos and conveyor systems to serve both wells efficiently. Prioritize larger volumes near the 3000m well.

•Water Storage: Ensure sufficient storage tanks are available for both wells, with pipelines or trucking routes established for quick resupply.

•Data Vans: Deploy one van per well for real-time monitoring and coordination.

Shared Resources:

•Utilize shared blenders and chemical units for flexibility.

•Prioritize fast repositioning of equipment between wells if needed.

3. Execution Strategy

Prioritize the 3000m Well (Critical Path)

1.Start Frac Operations on the 3000m Well Immediately:

•Begin pumping stages at high intensity to maximize daily progress.

•Use tight stage spacing (40-50m) to ensure optimal reservoir contact.

•Plan for 4-5 stages per day, targeting completion of 30-40 stages (~80-100% of the well) within 8 days.

2.Initiate Zipper Fracking with the 1000m Well:

•Once initial stages on the 3000m well are underway, start fracking the smaller well.

•Use a zipper fracking approach: Prep stages on one well while pumping on the other to reduce downtime.

Pre-Rain Milestones:

•Aim to complete 100% of the 1000m well and 80-90% of the 3000m well before rain arrives.

•If delays occur, prioritize finishing the smaller well to free up resources for post-rain operations on the larger well.

4. Mitigate Weather Risks

1.Site Preparation:

•Improve pad drainage to handle heavy rain and prevent equipment from getting bogged down.

•Stockpile sand, water, and critical consumables on-site to minimize the impact of disrupted supply chains.

2.Contingency Plan:

•Prepare for a possible pause during the rain by coordinating with local weather services for accurate forecasts.

•Focus on completing the most critical stages (e.g., toe sections of the wells) before operations are interrupted.

•Secure frac equipment and chemical storage against flooding risks.

5. Monitor and Adjust in Real-Time

•Use real-time data monitoring from the frac fleet to optimize rates, pressures, and stage transitions.

•Adjust resources dynamically based on well performance or unforeseen delays.

Summary Timeline

•Day 1-8: Focus on completing the 1000m well and progressing most of the 3000m well.

•Day 9-10: Transition remaining resources to finalize high-priority stages on the 3000m well.

•Post-Rain (if needed): Finish remaining stages on the larger well, leveraging the fleet’s flexibility.

This strategy maximizes productivity within the 10-day window while mitigating weather risks and ensuring both wells are fracked efficiently.
