Overview of Downhole Tubulars - Oil and Gas Wells

The jump from junior framing to senior tradeoffs shows up fast here; it's explicit without being preachy. In the Tubular Design Walkthrough, the collapse vs burst example using a 7‑in casing at ~9k ft stuck, especially the safety factor callouts. I liked how failure modes tie back to arch and ops, though I wasn't sold on the brief nod to obs and wished for more on closing the loop with field data. By the end I've got notes translating this into our infra repo—naming, PR checks, and a CI gate I'd add.

Needed a clearer mental model of what’s actually inside the hole, and this filled gaps without marketing fluff. The section on casing vs tubing around the burst/collapse calc with API J55/N80 table stuck, plus the animation at 22:10. It mapped components like an arch diagram; think prod failures traced via obs, not k8s—mostly worked, though I wished for more on workover edge cases. it's answered questions I've been parking for a year while skimming well reports and PRs in the repo.

Dense material without the fluff; it moves fast but stays readable. The Module 3 casing vs tubing section, especially the burst/collapse walk-through using API 5CT grades, stuck with me because it mirrors spec reviews I see before prod changes. I've already used that framing to sanity-check a client’s arch decisions on connections and weights, which saved a back-and-forth. Wasn't sold on the brief metallurgy pass; wished there was more on sour service failures and photos.
