Casing/cementing/zonal isolation
A multidimensional Wiener process approach predicts casing remaining useful life, enabling safe, cost-effective well life extension and repurposing for carbon dioxide injection, CCS, and geothermal applications.
The paper describes a multientry multistage fracturing technology developed to enable longer laterals, increase stage counts, improve stimulation efficiencies, and derisk operations.
This study identifies critical knowledge gaps in wellbore integrity and underscores areas that require further investigation, providing insights into how wellbores must evolve to meet the technical demands of the energy transition.

An analysis of existing wells in the Martin Linge field, conducted by Equinor when it took over as operator from Total, revealed that several did not have sufficient barriers, leading the company to plan new wells to ensure safe operation. -
In tectonically influenced regions, potential hydrocarbon traps are subject to complex states of stress. This scenario often translates into severe strike/slip (SS) and thrust-fault or reverse-fault (TF/RF) stress states.

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.
