This edition highlights three offshore technology papers that address a common industry theme: how targeted engineering solutions can reduce uncertainty, shorten operations, and make technically constrained offshore well activities more executable.
Three papers are highlighted as the primary contributions because of their broad industry relevance. They focus on improving formation particle-size characterization, expanding the application of openhole gravel packs in depleted and compartmentalized reservoirs, and advancing the understanding of capillary pressure in sand production.
This paper aims to establish a set of best practices for generating particle-size-distribution data from core samples.

The first long-haul overland conveyor system to deliver proppant is under construction in the Permian Basin. -
Coiled tubing has a key role to play, with strong arguments for itself: It is used throughout the life of a well, from exploration to abandonment, and its flexibility of use, combined with recent technology developments in pipe materials, real-time downhole telemetry, and specialized downhole tools—just to name a few—opens avenues to perform in a rigless manner many o…

The first acid job dates to 1895. Challenges remain, however, when it comes to lithology, coverage, penetration, and management of reaction products. These themes remain a focus for stimulation engineers.
-
When there are two ways to measure something, and they offer significantly different numbers, which do you use?
-
Fracture monitoring to optimize fluid volumes and designs remains a critical area of development. Research is ongoing with the focus on combining different monitoring technologies including tracers, fiber optics, downhole cameras, and microseismic monitoring.
-
This paper describes efforts at the Hydraulic Fracturing Test Site 2 to collect a research data set to improve understating of spatial and temporal hydraulic fracture dimensions, proppant distribution, and reservoir depletion.
-
This study illustrates how a combination of a straddle-packer system and a downhole real-time telemetry successfully stimulated up to 38 stages while maintaining packer-seal integrity and downhole pressure.
-
This paper presents an integrated system for fracturing optimization using real-time and historical data along with organizational knowledge and the challenges and key considerations of implementing such a system.
-
This paper describes the analysis of actual performance data for acid fracturing in a tight carbonate formation to investigate the ineffectiveness of the process.
-
The authors of this paper describe an underbalanced coiled-tubing drilling campaign in the operator’s onshore fields using a closed-loop system design.
