The productive life of certain wells with frac-pack sand-control completions has shown a greater decline in performance than expected. In many cases, this abnormal decline, both initially and in the long term, can be attributed to loss of conductivity in the proppant pack. Because conductivity is the major design criterion for frac-pack completions, the conductivity must be optimized in the original completion and then maintained throughout the life of the well. When frac packing in weaker and unconsolidated environments, enhanced treatment materials and designs must be used to help ensure that frac-pack conductivity is optimized initially and maintained over the long term. |
