Abstract
Fit-for-purpose well completion designs are not uncommon in the oil and gas industry. The broad range of downhole conditions encountered in the diverse fields where we operate makes it difficult to standardize equipment across the globe. By and large, the well functional requirements (e.g., sand control, zonal reservoir control) outweigh blanket selection criteria based solely on supplier cost and availability. Yet, it is the supplier capability and how the equipment is installed and operated that dictates the success of a field campaign. This presentation examines the life cycle of completion equipment from concept selection, detailed design, and through manufacturing, installation, and well performance. We will discuss some actual examples of equipment issues that led to deployment and production risks as well as the measured steps and tools that can help mitigate equipment related failures.
