Drill-in fluids and associated methods |
| abstract |
Of the many methods provided, in one embodiment, the present invention provides a method comprising: placing a drill-in fluid in a subterranean formation, the drill-in fluid comprising an aqueous base fluid, a viscosifier, a relative permeability modifier fluid loss control additive, and a degradable bridging agent comprising a degradable material capable of undergoing an irreversible degradation downhole; and forming a self-degrading filter cake comprising the bridging agent upon a surface within the formation whereby fluid loss through the self-degrading filter cake is reduced. |
