Completions
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.
This paper discusses the successful execution of two openhole gravel-pack completions in two Gulf of Mexico fields with depleted reservoirs.

Schlumberger and a Middle East offshore logistics company signed an agreement to develop a modular stimulation vessel as part of Qatar’s program aimed at localizing the energy sector’s supply chain and creating new investment opportunities. -
Bringing the Heat: Aramco Field Tests High-Temperature Chemistry To Slash Tight-Gas Completion CostsSaudi Aramco and university researchers are experimenting with a thermochemical fracturing fluid that aims to eliminate more than half of the pumping horsepower typically required to complete horizontal wells.

Specifically targeting ingrained thinking, the selected papers demonstrate the game-changing results that can be achieved even when targeting long-established norms. They demonstrate everything that our industry should be proud of and what we strive for.
-
This article addresses a means to improve hydraulic fracturing operations by measuring the perforation effectiveness on a stage-by-stage basis before the hydraulic fracturing process begins.
-
The complete paper discuses a well with a history of sand production that exhibits long cyclic slugging behavior.
-
Sand control has evolved over the years; however, the fundamentals of screen sizing have not changed. Particle-size distribution remains the basis for most designs. Laser diffraction has provided better definition of fines, and greater focus is placed now on particle-shape characterization.

Traditionally, a wellhead system requires a drilling lockdown sleeve (LDS) during drilling operations to ensure that the seal assembly is rigid and prevents dynamic movement. By eliminating the LDS, however, the operator will save multiple trips into the well.
-
The complete paper describes the development and implementation of a glass-plug solution that closed the technical gaps that had previously inhibited fully intervention-free operation for completion installation.
-
The complete paper describes and quantifies the stress-dependence of compaction and permeability for anisotropic rock matrices, natural fractures, and hydraulic fractures, based on comprehensive rock tests of a fractured tight reservoir.
-
The complete paper presents a strategy for selecting a surfactant/solvent package for parent wells. Oil recovery and associated water saturation in the microfluidic-based device, with or without surfactant, are quantified and reveal that the oil recovery is enhanced with surfactant.
