10 Practical Approaches to Sand Management
In weak and unconsolidated reservoirs, the production of sand obstructs flow, erodes downhole and surface hardware, and costs operating companies billions of dollars annually. Reservoir experts who seek to manage this problem effectively must focus on production optimization. This article discusses sand prediction, prevention, monitoring and remediation, and presents examples in which proper sand management has had a significant impact on project success.
4 Better Turns for Rotary Steerable Drilling
Substantial advances in the reliability and steerability of rotary steerable drilling systems allow engineers to plan and drill complicated well trajectories in extremely demanding environments. Case histories demonstrate how advanced rotary steerable systems improve well placement and hydrocarbon recovery.
28 Perforations on Target
Perforation misalignment is a significant problem that often leads to excessive sand production and poor well performance. New tool designs, linked with interdependent technologies, place perforations on target.
On the cover:
A CT EXPRESS* rapid-deployment service unit rigs up on a Permian Basin well near Midland in the early hours of a West Texas, USA, morning. The coiled tubing unit and separate trailer-mounted system for pumping treatment fluids, nitrogen and liquid additives were designed specifically for low-pressure, intermediate-depth wells.
