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 18):
The method of  claim 14 , wherein the filter cake particles are selected from the group consisting of calcium carbonate, hematite, ilmenite, manganese tetroxide, manganous oxide, iron carbonate, magnesium oxide, barium sulfate, salts thereof, and mixtures thereof.
