Dedicated teams and the integration of proven technologies and work flow processes help address the complexities inherent in building deepwater wells. Predrill knowledge allows timely construction based on optimal parameters. Accurate while-drilling and survey data allow the operator to avoid drilling hazards and produce optimal wellbore to enable all subsequent operations. Reliable service quality, deepwater experience and expertise—at every step and from every team member—are key to placing the well on target in the fastest, most economical, and safest way possible, ready for casing and cementing.
In deepwater operations it's imperative to select the rotary steerable system that best provides accurate well path control in the specific drilling environment. The PowerDrive system uses full rotation to deliver precise trajectory control when drilling the aggressive doglegs deepwater wells often require. Continuous surveys and fast downlinking also improve drilling speed by eliminating micro-NPT.
Real-time monitoring of data from multiple sources leads to a better understanding of the drilling environment, including geomechanics and shock and vibration. This information is used to adjust and optimize drilling parameters for maximum ROP in a variety of environments. The goal is to deliver a wellbore quickly, cost-effectively, and safely—and one that is ready for casing and cementing.
Deepwater operations require special cementing knowledge, technologies, services, and products to ensure zonal isolation and casing integrity where temperature and pressure variations may compromise standard systems. Experts use proven workflows to design appropriate surface casing and to determine the best use of riser and riserless technologies.
