摘要： The present invention provides a method of treating a subterranean formation with a particulate laden fluid whereby particulate flowback is reduced or prevented. The method includes the steps of providing a fluid suspension including a mixture of a particulate, a tackifying compound and a hardenable resin, pumping the suspension into a subterranean formation and depositing the mixture within the formation whereby the tackifying compound retards movement of at least a portion of the particulate within the formation upon flow of fluids from the subterranean formation and said hardenable resin subsequently consolidates at least a portion of said particulate within said formation.

摘要： Improved methods of placing a gravel pack in a wellbore and in one or more perforations extending from the wellbore into a producing zone are provided. The methods basically comprise the steps of placing a screen in the wellbore adjacent the perforations, and then injecting a low viscosity carrier liquid having a particulate solid pack material suspended therein into the space between the screen and the walls of the wellbore containing the perforations. The pack material has a specific gravity substantially the same as the specific gravity of the carrier liquid whereby a low viscosity carrier liquid can be utilized and the carrier liquid-pack material suspension contains a high loading of pack material.

摘要： The present invention relates to a method of hydraulically fracturing a first zone with a first fluid and an adjacent second zone with a second fluid which preferably is chemically reactive with the first fluid to produce a precipitate or gel upon contact therewith. Preferably the fluids are separated from one another in the wellbore and are pumped into their respective zones at approximately the same rate so that they spread radially outward from the wellbore into the formation. Upon contact, the two fluids react with one another to form a precipitate or gel at the interface between the two zones thereby arresting further fracture propagation between the zones.
摘要翻译：本发明涉及一种用第一流体和相邻的第二区域水力压裂第一区域的方法，其中第二流体优选与第一流体发生化学反应，以在与第一流体接触时产生沉淀物或凝胶。优选地，流体在井筒中彼此分离，并以大致相同的速率被泵送到它们各自的区域中，使得它们从井眼径向向外扩展到地层中。接触后，两种流体彼此反应，以在两个区域之间的界面处形成沉淀物或凝胶，从而阻止区域之间进一步的裂缝传播。
