This paper describes the startup and application of coiled tubing- (CT-) conveyed fracturing for sand-control purposes in an oil field in Indonesia. Sand production becomes a major problem where well servicing is routinely performed to replace worn or stuck subsurface artificial lifting equipment. Some of the producer wells are slimhole, which prevents the use of conventional sand control using screen and gravel because it restricts the production flow severely. A recent field test was performed in four wells by fracturing through CT to provide screenless completion. The ultimate goal was to achieve an acceptable sand control in these weak formations while restoring production. We demonstrate that not only did the treatments achieve the objective but they also stimulated the well and improved well management.
