Rapid Lost Circulation Cure: ABRAJ Energy Services' Fiber-Enhanced Cementing Solution

Lost circulation is defined as the escape of drilling fluid into subsurface formation voids. This is a costly challenge in oil and gas exploration. ABRAJ Energy Services has adopted a fiber-enhanced cementing solution that quickly and permanently seals these voids, mitigating severe losses. Key features and benefits of this approach include:

• Single-Trip Remedy: A specially formulated fiber-cement slurry is pumped through the bottom-hole assembly (BHA) into the loss zone, immediately bridging fractures and forming a durable plug. Circulation is typically restored within hours rather than days.
• Reduced NPT and Costs: Lost circulation commonly accounts for over 10% of drilling downtime and up to 20% of total drilling costs. One study reported more than 100 hours of non-productive time (NPT) and $185,000 in added costs per well. In Oman, ABRAJ Energy Services' method restored circulation after a single treatment, saving 72 hours (equivalent to $100,000).
• Improved Well Integrity and Safety: The fiber-cement plug rapidly stabilizes the wellbore, maintaining control and supporting successful casing cementing, thereby mitigating risk and eliminating the need for costly remediation efforts.
