... Abstract Many horizontal/multilateral wells are drilled using water-based mud. In general, drilling fluids consist of xanthan, starch or polyanionic cellulose with bridging agents like sized calcium carbonate and salt particulates. During drilling and completion operations, it is essential...

... to increase the fracture reopening pressure, it may still be of benefit to cause fracture tip screen-out. An example is the differences seen in these tests for calcium carbonate versus the DEA 13 project results (discussed later) where the large sample size allowed fracture tip screen-out.
