Casing wear is an increasingly typical problem that leads to a decrease in collapse resistance in deep wells, ultradeep wells, horizontal wells, and extended reach wells. Casing wear is an ...

Back to basics with today’s graphic, with a look at the different ways compounds in organic chemistry can be represented. Obviously, if you’re a chemist, these will all be second nature, but as was ...
