Drilling

Laboratory formation damage testing is often used to help select optimal drilling and completion fluids, but predicting the overall effect of formation damage on well performance requires further interpretation. Paper SPE 199268 presents a case for use of CFD to upscale laboratory data to quantify that effect.
The qualification and first deployment of a low-solids, oil-based completion fluid that incorporates a newly developed, high-density brine as the internal phase to extend the density limit is discussed.
Laboratory studies performed for evaluation of filter cake breaker fluid exposed limitations with a conventional test approach.
