Abstract
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.
