The application of automated technologies to the process of well construction is emerging as key to improving the overall efficiency of drilling performance. Though not yet mainstream, several recent applications have demonstrated that technology maturity is no longer the limiting factor in accelerating implementation and realizing the benefits of automation. This paper describes a collaborative effort between an operator, a drilling contractor, and a service company to introduce specific aspects of automated technology to a major drilling operation.
In 2012, the company began developing a giant gas greenfield that required nearly 300 wells to be drilled. Among the many challenges on a project of this magnitude was the need to drive well-construction costs down. An important aspect of well-construction cost is the time spent drilling, which is largely influenced by the slow rate of penetration (ROP) prevalent in the field because of the high rock strength. In order to deliver the performance enhancements required, the company set up an integrated hard-rock drilling team.
In addition to the objective of increasing ROP, several other aspects of the technology made it attractive. These include that
