METHODS AND FLUID COMPOSITIONS FOR DEPOSITING AND REMOVING FILTER CAKE IN A WELL BORE |
摘要 |
<p>The current invention provides methods of using and drilling and servicing fluid compositions for depositing and removing filter cake from the walls of a well bore. The compositions make use of particulate solid bridging agent comprised of a salt of an organic acid. The bridging particles are dissolvable by a clean-up solution comprised of a mild solvent that is less corrosive than the conventional strong mineral acids used for this purpose.</p> |
