Abstract
Polymer-based drilling fluids may be used as an alternative to drilling fluids containing bentonite or other clay materials, although filter cake formation with polymer-based drilling fluids can often be inadequate. Drilling methods can comprise: providing a drilling fluid comprising a carrier fluid, a non-crosslinked hydroxyalkylcellulose polymer, and a plurality of non-biodegradable particulates; drilling a borehole in the presence of the drilling fluid; and forming a filter cake within the borehole, the filter cake comprising the non-crosslinked hydroxyalkylcellulose polymer and the non-biodegradable particulates.
