Paper: How Bottom-hole Conditions Affect Design of Squeeze Cement Jobs

The success ratio of squeeze cementing operations in the past has been poor. A lack of knowledge of downhole conditions and formation characteristics was partly to blame. Proper cementing materials for downhole conditions were not always available. Recent development of cementing materials and techniques has greatly improved the success ratio of squeeze cementing. New tools are available to provide a greater knowledge of downhole conditions to determine the existing problems in the well. New cementing materials have been developed so that a cement slurry can be tailor-made for each particular set of well conditions. Laboratory equipment is available now to stimulate downhole conditions in testing cementing materials in squeeze slurries. With the knowledge and materials available today a squeeze cementing job designed on the surface will, in most instances, perform down the hole.
