Remedial cementing is performed to correct problems associated with the primary cementing job. This article describes some common techniques for placing the cement in the correct location to correct the problem. These techniques are described in basic terms; they can be custom-designed for specific situations, and depend upon the type of remedial cementing operation being undertaken. Dump bailers are used for placing very small volumes of plugging material precisely and economically. Different types of dump bailers, including gravity and positive-displacement bailers, are shown inFigure 1.

...ns are required to clean out the well and restore productivity. One cleanout technique is to run a "bailer" on a wireline to remove the sand from the production tubing or casing. Because the ...bailer removes only a small volume of sand at a time, multiple wireline runs are necessary to clean out th...
Conventional well completions in soft formations (the compressive strength is less than 1,000 psi) commonly produce formation sand or fines with fluids. These formations are usually geologically young (Tertiary age) and shallow, and they have little or no natural cementation. Sand production is unwanted because it can plug wells, erode equipment, and reduce well productivity. It also has no economic value. Nonetheless, formation sand production from wells is dealt with daily on a global basis.
