Drilling

Field Experience: Diagnosing a BHA Washout During a drilling operation, a gradual reduction in SPP was observed, eventually reaching 500 psi. After monitoring the trend and evaluating possible causes, the decision was made to POOH and inspect the drill string and BHA for signs of a washout. Upon inspection, a significant washout was found at the connection between the string stabilizer pin (upper component) and the float sub box (lower component), as shown in the attached photos. Based on the washout geometry visible on both components, which failure mechanism do you believe occurred first? Scenario 1: The float sub box developed a crack or defect first, initiating the washout and subsequently damaging the stabilizer pin connection. Scenario 2: The stabilizer pin developed a crack or defect first, initiating the washout and subsequently damaging the float sub box connection. I am interested to hear the opinions of drilling, L/MWD, directional drilling, and drilling tool specialists. Which scenario would you support, and what evidence from the washout pattern leads you to that conclusion? ✍ Credit

Field Perspective Note #1 Practical Wellsite Checks Before Casing Operations ✍ Ali Al Naimi

Field Perspective Note #1 Practical Wellsite Checks Before Casing Operations Casing operations are routine, but many avoidable issues originate from missed basic checks rather than complex technical failures. In my experience, disciplined preparation is often the biggest risk reducer at the wellsite. Below are practical checks that consistently add value before running casing: 1. Program and Design Alignment Ensure the casing program, tally, and accessories are fully aligned with the latest approved well program. Any last-minute changes must be clearly communicated to the rig crew and service providers to avoid assumptions on site. 2. Equipment Readiness and Compatibility Confirm casing, threads, centralizers, float equipment, and handling tools are correct, inspected, and compatible. Early verification reduces delays and prevents rushed decisions once operations begin. 3. Hole Condition and Well Control Readiness Review hole condition data, circulation parameters, and displacement volumes. Verify well control barriers, checklists, and monitoring responsibilities are clearly assigned in line with well control requirements. 4. Roles, Responsibilities, and Communication Clear definition of responsibilities between company, contractor, and service personnel is critical. Pre-job safety meetings and JSA discussions should address not only hazards, but also decision-making and escalation pathways. 5. Post-Run Verification and Documentation After reaching target depth, verify casing depth and tally accuracy before moving to the next phase. Record key parameters and any anomalies clearly to support proper handover and operational continuity. Final thought: Strong casing operations are rarely about doing something extraordinary. They are usually the result of consistent preparation, clear communication, and disciplined execution. #DrillingOperations #WellDelivery

An exciting project in collaboration with Equinor/ Archer. Expro is the first in the world to carry out this type of operation completely without personnel in the Red Zone. This is not just about technology – it’s about: ✅ Increased safety ✅ Eliminating exposure in the Red Zone ✅ Significantly faster operation than traditional methods ✅ Major savings in rig time 🔗Credit

⁉️🆘 We obtained video of Doyon 26, known as the Beast, tipping over on the North Slope. It's the largest mobile land drilling rig in North America. The rig weighs nearly 10 million pounds. ConocoPhillips say there were no serious injuries.

Casing Running Tool (CRT): A Critical Tool for Safe & Efficient Casing Operations In drilling operations, running casing is a high-risk and precision-critical task. The Casing Running Tool (CRT) plays a vital role in ensuring this process is done safely and efficiently. The CRT is designed to grip, lift, rotate, and torque casing strings, allowing smooth running into the wellbore while maintaining full control at surface. It also enables circulation and rotation, which is essential for hole cleaning and preventing differential sticking. Key benefits of using a CRT: • Improved safety by reducing manual handling • Precise torque and rotation control • Faster casing running operations • Better well integrity and reduced non-productive time (NPT) From surface handling to final casing landing, the CRT is a small tool with a huge impact on well success. 🔗 Credit
