2016 ISP: Global LTI, recordable incident rates both down, but number of fatalities ticks up slightly

March accounted for the most Lost Time and Recordable incidents. The 26-35 age range accounted for the most Lost Time and Recordable incidents.

Numbers from the latest IADC Incident Statistics Program (ISP) are encouraging. The ISP, which has tracked safety and accident information for the drilling industry since 1962, shows that the worldwide lost-time incidents (LTI) rate improved by 27.7% from 2015 to 2016, going from 0.18 to 0.13. The recordable incident rate also saw improvement, falling by 23.3% from 0.60 in 2015 to 0.46 in 2016...

Digital transformation


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....

Remembering Bob Keller


Bob Keller, Rowan Retiree and rig namesake, passed away on 24 July at the age of 91. He began working for Rowan Drilling immediately following his graduation from Texas A&M in 1947. He started as a roughneck on a steam rig in Alvin, Texas, and proceeded to work in almost all of Rowan’s operating regions at the time, including the Southern, Western and Rocky Mountain Divisions, the Gulf of Mexico and Southeast Asia. After 43 years of service, Mr Keller retired as Vice President of Operations for Rowan Companies Inc. on January 1, 1991. In 2005, a TARZAN Class jack-up rig was named in his honor. Mr Keller said his proudest achievement at Rowan was training the “young people” of Rowan ...

Automation of surface equipment, dissolvable and shorter plugs push efficiency of fracturing operations

Terves’ Response Element DE 50 is a fully dissolvable polymer that is being used to make frac plugs.

Increasing use of water due to longer laterals and higher stage counts are also driving demand for more cost-effective water management solutions By Kelli Ainsworth, Associate Editor As operators push the number of stages per well to upwards of 75 or even 100 in some plays, they’re also demanding step-changes in the efficiency of hydraulic fracturing technologies and equipment, including associated technologies like water management systems. A significant area of focus has been on reducing plug mill-out time, with more dissolvable technologies coming to the market, as well as the development of shorter plugs with less material to mill through. Technologies are also emerging to automate the surface operations of hydraulic fracturing. While the industry has made significant progress in ...
