Paper: Primary and Remedial Cementing in Fractured Formations

Successful design of primary and remedial cementing procedures in fractured formations requires a precise analysis of down-hole conditions, and careful definition of design objectives. Collection of fracturing pressure data is stressed, and methods for applying this information to cementing design are the primary considerations. Remedial cementing is regarded as the more difficult design, and emphasis is placed on this phase of cementing. The use of controlled water loss cement, packer applications, and placement techniques are considered as a basic part of remedial design. Several unique designs successfully used in Western Permian Basin are included.
