By using new technology and software, multidisciplinary teams plan and implement customized strategies to improve reservoir characterization, increase oil and gas output, and optimize recovery. Performance monitoring, data management and, eventually, real-time systems with downhole control will complete the reservoir management cycle, providing continuous feedback to anticipate or solve production problems and help capture additional asset value.
Drilling with coiled tubing has evolved from an experimental technique to a proven technology now used for nearly half of all new wells on the North Slope of Alaska, USA. Specially designed arctic coiled tubing units can move, rig up and begin work in a matter of hours. By working concentrically through large production tubulars, wells can be sidetracked at lower cost than with conventional drilling rigs.
Drilling and completing wells in HPHT environments is difficult and dangerous. But as activity in these areas expands, transferring experience, expertise and knowledge about the best techniques from person to person and well to well is essential to reduce risks, increase safety and efficiency, and ultimately, improve financial returns.
As the search for oil and gas leads to deeper reservoirs, extreme pressures and temperatures have become key considerations in reservoir development. Innovative technologies are being developed to meet the challenges of evaluating and completing HPHT wells and bringing these fields on-stream.
