Drilling
This paper discusses tools and techniques used to localize a tubing leak in a horizontally completed multilateral well, identifying the bore responsible for sand production and providing relative sand quantification at differing flow rates.
This paper presents an approach to optimize the location of wellhead towers using an algorithm based on multiple parameters related to well cost.
Optimizing and continually increasing efficiencies at every stage of the drilling and completion process are central themes in the papers showcased in this feature. Innovating our way through difficult times is what the oil and gas industry excels at, especially during challenging periods. During the COVID-19 pandemic, the offshore energy industry faced immense strugg…

In 2022, the topics of the cementing and zonal isolation papers published were generally similar to those presented in previous years. A noticeable departure from previous years, however, was that many of the authors emphasized that their work would result in a reduction of greenhouse-gas emissions.
