When you shut in your wellbore an increment in water saturation can cause reduction in relative permeability and as a result loss of well productivity. Production loss of 20-70% is not uncommon and are caused by numerous factors as wells are brought back online:
• Unpropped Fracture Closings
• Proppant Crushing and Embedment
• Pressure Drawdown
• Unknown Status of each cluster
• Waterlock
• Proppant Crushing and Embedment
• Pressure Drawdown
• Unknown Status of each cluster
• Waterlock
Bullheading treatment fluid is often performed to regain production, however; this method does not address or repair near wellbore damage caused by the shut in across the entire lateral, leaving large volumes of valuable hydro-carbon behind.
DATA- DRIVEN APPROACH TO REFRACTURING
Our downhole pressure data suggest that injection pressures can vary by 4,000 psi or more from one cluster to another, providing the need for mechanical isolation to ensure precise treatment placements and prevent the fluid from taking the path of least resistance.
The Comitt EXCITE System is ideal for these applications as you can stimulate every cluster, ensure 100% product placement, and surgically remove near wellbore damage from the shut-in along the entire lateral. Downhole pressure & temperature gauges on the tool confirm product placement and give a precise map of clusters previously untreated in the initial frac, providing data-driven decision making for future production optimizations and refrac evaluations.
