Casing/cementing/zonal isolation
This paper describes an intelligent completion system in the context of multiple wells that, by electrifying the process, replaces the conventional electrohydraulic systems that have been in use for decades.
To enable a fully interventionless approach, a barrier-rated tubing-hanger valve has been developed to eliminate slickline intervention and minimize associated risks and operational time.
This paper investigates the effect of calcium oxide as an expansive agent on the performance of geopolymer-based sealing materials, with successful application in oil and gas wells at shallow depths.

The cementing services market size in the US is expected to drop 50% year-on-year from 2019. The significant drop in Permian Basin activity will account for 40% of the total market size reduction. -
In the complete paper, a novel system that uses engineered features of permeable polymeric shell walls for the controlled release of encapsulated cargo is described.

This year, excellent papers have been presented, augmenting our knowledge and responding to the challenges of complex wells and efficiency requirements. At the same time as we “Strengthen the Core,” we continue to focus on design, delivery, and evaluation of cementing operations.
-
The complete paper presents a case study in which offline cementing improved operational efficiency by reducing drilling times and provided significant cost savings.
-
This study used ultrasonic logging to evaluate reference barrier cells constructed with known defects. The cell concept was developed with an emphasis on low cost and ease of use.

This paper describes a high-pressure/high-temperature (HP/HT) expandable liner hanger product that offers metal-to-metal and elastomer sealing capabilities at the liner top in the host casing.

This case study discusses the methodology that underlies the successful determination of the depths and the radial locations in the outer casing strings of multiple leaks in an offshore well.
-
This paper describes the mobilization of a snubbing unit and blowout preventer (BOP) stack in the Middle East that enabled a well with an underground blowout and surface broaching to be brought under control within a short time.

SponsoredRunning casing to depth in long lateral sections is challenging, often costing operators a significant portion of pay zone at the toe of the well. This article highlights a technology that helped one operator add $120,000 to its incremental gas recovery.
