Casing/cementing/zonal isolation
The authors describe a study analyzing a comprehensive data set recorded in casing-cemented sandwich sections and recovered during the abandonment of a well in the Valhall Field.
The authors seek to eliminate the need for pressure testing in the evaluation of annular creep barriers by qualifying the barrier using only cased-hole log measurements.
In the October 2021 issue of JPT, incoming SPE President Kamel Ben-Naceur discussed the importance of collaboration in solving technical problems quickly and efficiently. Three of the papers selected in this section are from collaborations between multiple companies pooling their expertise and resources to develop solutions for complex problems that could not be addre…
