Abstract: Methods for drilling a wellbore into a subterranean formation include preparing a drilling fluid and circulating the drilling fluid in the wellbore while drilling in the subterranean formation, forming a filtercake from the drilling fluid, creating or encountering one or more fractures in the subterranean formation while drilling, and allowing a portion of the filtercake formed to at least partially seal the one or more fractures while continuing the drilling.

Abstract: Pumpable process-fluid compositions comprise polyacrylamide, a non-metallic crosslinker and a pH-adjustment material. Such compositions have utility in the context of controlling lost circulation in subterranean wells. Upon entering at least one lost circulation zone, the compositions crosslink, thereby forming a barrier that minimizes or stops fluid flow from the wellbore into the lost circulation zone.

Abstract translation: 可泵送的工艺流体组合物包含聚丙烯酰胺，非金属交联剂和pH调节材料。 这种组合物在控制地下井中的流失的情况下具有实用性。 在进入至少一个失水循环区域时，组合物交联，从而形成最小化或阻止流体从井眼流入损失循环区域的阻挡层。
