Reentry drilling, reservoir stimulation and wellbore recompletions often need to be performed without rotary rigs or conventional workover units as a means of maximizing production economics.
Coiled tubing allows remedial operations to be performed under pressure, or ??live?? conditions, without pulling well tubulars. Collaboration between operators and providers of this technology continues to yield tools and techniques that improve productivity in both new and mature fields.
Many operating companies are turning to through-tubing, or concentric, operations to solve difficult production problems and to meet demanding well-intervention or wellborerecompletion challenges. Steeply declining production output and insufficient replacement of oil and gas reserves have compelled operators to reexamine field-development strategies and reservoir-management efforts. Increasingly, asset managers need to optimize the performance of both new and existing wells to meet global demand for petroleum.
