Abstract:
A treatment composition may contact an oil-based mud (OBM) filter cake formed over at least part of a wellbore for cleaning the filter cake by incorporating more oil and/or filter cake particles into the treatment composition as compared to an otherwise identical filter cake absent the treatment composition. The treatment composition may include, but is not limited to, a surfactant, an aqueous-based fluid, an agent, an optional second acid, and combinations thereof. The agent may be or include long chain alcohols, phenol derivatives, fatty esters, a first acid, and combinations thereof. The first acid may be or include a diacid. The diacid may be a polycarboxylic diacid, such as but not limited to [N-(1,2-dicarboxyethylene)D,L asparagine acid] (IDS), polyaspartic acid (DS), ethylenediamine-disuccinic acid (EDDS), [N,N-bis(carboxylmethyl)L-glutamic acid] (GLDA), methylglycinediacetic acid (MGDA), salts thereof, derivatives thereof, and combinations thereof. The tetraacid may be ethylenediaminetetraacetic acid (EDTA), hydroxyl-ethylenediaminetetraacetic acid (HEDTA), and the like.

Claim (Index 17):
The method of  claim 14 , further comprising generating the treatment composition in situ downhole when contacting the OBM filter cake with the treatment composition.
