| titleOfInvention | FLUID FOR DRILLING WELLS AND TREATMENT FORMATION TREATMENT METHODS. |
| abstract | The present application describes improved compositions for drilling well fluids for use in downhole applications (eg, oil wells). The compositions comprise a block isocyanate component (BI) having a tolerance enhancing group (such as a hydrophilic group, for example, an amine) linked thereto, and an active hydrogen component. When the BI group is unblocked, it reacts with the active hydrogen component to form a gel which, by virtue of the tolerance enhancing group, is more tolerant to contaminants (such as inorganic aqueous salts or brines) than the corresponding gel forms of unmodified BI. The application also refers to methods of treating a land formation when using such a composition. |
