In the world of core acquisition, success doesn’t start at the drill site—it starts long before. At US Coring, we’ve seen firsthand how effective pre-job planning directly influences the outcome of a core job. Whether you’re operating in a conventional reservoir or exploring unconventional formations, the time and attention you dedicate before the bit hits the ground can be the difference between capturing critical data—or missing it altogether.



1. Clear Objectives = Better Execution

Every core job should start with a clear understanding of the end goal. Are you coring for reservoir characterization, mechanical testing, or geochemical analysis? Pre-job planning ensures everyone—from drilling to geology to our coring team—is aligned on expectations and objectives. With clearly defined deliverables, we can design the right approach for your job, minimizing surprises and maximizing recovery.

2. Customized Tool Selection

There is no “one size fits all” in coring. Planning ahead allows us to select the right type of coring system, barrel length, and cutting structure suited to the formation and well conditions. This is especially important when facing formation sensitivity, pressure challenges, or long intervals. The better the plan, the more precise the equipment—and the better the results.

3. Risk Mitigation & Contingency Planning

Formation damage, stuck pipe, overpull, and core loss are all risks that can be mitigated with strong preparation. Pre-job planning allows us to anticipate these variables and develop contingency plans to maintain control and limit downtime. With the proper planning, problems don’t catch us off guard—they’re already accounted for.

4. Logistical Readiness

From rig layout to transportation to core handling and storage, planning ensures every aspect of the operation runs smoothly. This includes confirming availability of specialized tools, coordinating with lab partners, and ensuring rapid core retrieval and preservation—especially when dealing with sensitive or time-dependent data.

5. Improved Efficiency & Cost Control

A well-planned job runs smoother, faster, and more efficiently. That means fewer surprises, minimized non-productive time (NPT), and better budget control. When time equals money, good planning pays for itself.

At US Coring, we treat pre-job planning as a critical phase—not an afterthought.
Our team works closely with clients to understand their objectives, evaluate formation challenges, and build a custom plan to deliver accurate, high-value results. Because when the stakes are high, the margin for error is small—and the planning makes all the difference.
