Coiled tubing rigs lower cost in shallow plays

摘要

Although shallow plays appear to be an easy target, profitability remains a factor of lowering drilling costs. It is no secret that coiled tubing (CT) drilling rigs offer advantages over conventional rigs when it comes to ease of mobility, safety, environmentally friendly footprint, and drilling time. That said, CT drilling does have its limits. For many of today's growing shale plays, for example, the need for drilling vertical sections with even longer horizontal laterals keeps most CT drillers out of the market.
