Well control, like safety, is too important to be leveraged as a competitive advantage. That’s why Chevron is planning to share with the wider industry a tool – called DrillPad – that the operator launched in 2015 to assist with the planning and tracking of well control drills. The software was developed as part of Chevron’s WellSafe assurance program...

Deconstructing invisible lost time: KPIs, analytics, standardization improve well deliveries in Bakken

The equipment condition monitoring dashboard tracks the operational health of critical components of Nabors’ rigs worldwide. Personnel in the RIGLINE 24/7 remote operations center in Houston respond immediately to alerts on any issues affecting rig equipment performance.

A data-driven contractor-operator initiative that aimed to mitigate inefficiencies in the well construction process resulted in a “CAPEX-free” opportunity to safely reduce unconventional well delivery times by up to 40%. The joint initiative, which focused on North Dakota’s Bakken Shale play, underscored the tangible benefits of standardizing drilling operations and monitoring key performance indicators (KPIs) to consistently reduce invisible lost time (ILT). Unlike downtime, ILT never appears in the standard morning report. Rather, it is hidden inefficiencies and inconsistencies in routine drilling operations where performance in standard processes can often swing widely between crews...

The drilling industry has always been known for having big iron – from drawworks to iron roughnecks, from top drives to blowout preventers. But in today’s digital oilfield, it’s no longer hardware that’s driving the biggest changes at the rig site. Rather, game-changing technologies on the horizon are now almost entirely digital. Predictive analytics, the Internet of things (IoT), machine learning and artificial intelligence are not just buzzwords. They refer to real technologies that are increasingly being adopted into the drilling industry to improve efficiency and reduce costs....
