Abstract: The present invention provides a method of controlling fluid loss to a permeable formation penetrated by a wellbore. A novel fluid loss agent is prepared by forming a crosslinked polymer gel which then is sheared to break the gel into discrete particles of a particular size range. A slurry then is formed of the particles by dispersing the particles in an aqueous fluid having a density similar to that of the gel particles. The slurry then is introduced into contact with the permeable formation and a filter cake of the particles is formed upon contact with the formation and loss of the slurrying fluid to the formation. The filter cake provides further fluid loss control to the permeable formation.
Abstract translation: 本发明提供了一种控制由井筒穿透的可渗透地层的流体损失的方法。 通过形成交联聚合物凝胶制备新的流体损失剂，然后将其剪切以将凝胶破坏成特定尺寸范围的离散颗粒。 然后通过将颗粒分散在具有与凝胶颗粒的密度相似的密度的水性流体中，由颗粒形成浆料。 然后将浆料引入与可渗透地层接触，并且在与地层的形成和制浆流体的损失接触时形成颗粒的滤饼。 滤饼为可渗透地层提供进一步的流体损失控制。

Abstract: A method of preparing high density particulate slurries is provided whereby slurries containing in excess of 23 pounds of particulate per gallon of fluid can be introduced into a subterranean formation. In accordance with the method, a viscosified pad fluid is introduced into a wellbore to create a filter cake in a desired zone within a subterranean formation. The high density slurry then is introduced into the formation to substantially fill any annular space present without significant settling. This permits the coating of the entire exterior surface of highly deviated casing exposed within a wellbore.

Abstract: Methods for enhancing the conductivity of propped fractures in subterranean formations may involve using a tackifier to minimize particulate settling during particulate placement operations in subterranean formations. For example, methods may involve introducing a first treatment fluid into a wellbore extending into a subterranean formation at a pressure sufficient to create or extend at least one fracture in the subterranean formation; and introducing a second treatment fluid into the wellbore at a pressure sufficient to maintain or extend the fracture in the subterranean formation. The first treatment fluid may include at least a first aqueous base fluid and a tackifier. The second treatment fluid may include at least a second aqueous base fluid and a proppant particle.
