Dear forum members,
I have some challenging tasks to resolve. We are drilling deep wells on shore, (around 6000m) Recently we have been penetrating pay zones with OBM. Please share your experience regarding using oil based cement (cement settings, spacers). How to choose the best slurry for that kind of operations? Is that basically doable? We are going to use stage collar and run in one step. (TD 7" 5100m). Any advices would be much appreciated.
