Reservoir
This study explores the carbon-capture and mineralization potential of ultramafic rock powders when exposed to flue gases generated from combustion of crude oil and mesquite-derived charcoal.
This paper documents the testing, integration, and field deployment of a metal expandable packer used as an openhole toe isolation plug in a deepwater well under high-pressure, high-temperature conditions.
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.

Limited design capability, few number of field tests, and lack of monitoring and control were the reasons most EOR projects did not perform in the past. All those are history now. -
This study provides technical analysis of the viability of enhanced-oil-recovery (EOR) processes; the results indicate the potential for significant improvement in recovery efficiency over continued waterflooding.
-
Seismic innovators are working on new sound sources designed to produce better subsurface images while addressing concerns raised by scientists and regulators about the environmental impact of the related noise on sea life.
-
For engineering design teams, the market downturn is an opportunity to review practices and learn from others who have used hard times to reshape processes through simulation while cutting development time and costs.
-
A matured field is currently producing with greater than 85% water cut (WC) and has significant levels of uncertainty with respect to oil/water contact (OWC), flank structure, depth of spill points, production allocation, and residual oil saturation.
-
Rising demand for flowback technologies to reduce uncertainties is leading to the creation of more hydrocarbon and water tracers. These chemical-based tracers may play an important role in the shale industry’s effort to come up with more cost-effective fracture designs.
-
An area of great interest to those researching flowback is the interaction of water and salt inside the shale reservoir. After a well is stimulated, the flowback fluids tend to show a rising concentration of salt that falls back to near zero over time.
-
On the far end of the flowback spectrum is a completion process called soakback. If the well has to be shut in until takeaway capacity is available, the completion fluids soak into the shale rock. Flowback analysis can help understand what happens in the formation.
-
The need for cost and capital efficiency calls for careful integration of technical and commercial elements.

This paper will examine ways in which Chance of Development (CoD) can be defined better, methods for its estimation, and its appropriate application along with common misuses.
