Global land rig demand recovers, offshore still seeking inflection point

One year after setting record lows for utilization, the land rig markets in North America have seen a remarkable recovery. In the US, onshore rig demand surged by 105% to 976 active units, compared with 476 in the previous year. In Canada, there were 155 active land rigs during the census period, an increase of 65% over last year’s 94 units. Nevertheless, fleet utilization in both countries remain below normal at 46% (US) and 24% (Canada). Many lower-spec rigs are expected to exit the available fleet next year, as operators continue to give preference to higher-specification pad-capable rigs for development of onshore unconventional resources...

Perspectives: Roy Mills, Noble Drilling: Training now ensures drilling contractors will have skilled personnel ready when the next upturn comes

For Roy Mills, Subsea Systems Manager for Noble Drilling, offshore drilling is a family business. He grew up in Columbia, a small town outside of Monroe in northwest Louisiana. His father, like many other people in Columbia, built his 40-year career in offshore drilling. Three of his uncles were also in the drilling business. From an early age, Mr Mills knew he would follow in their footsteps. In 1991, on the day he turned 18, he started his first job as a roustabout on the Zapata Concord, a moored semisubmersible, in the Gulf of Mexico...

Failure analysis provides critical input for thorough root cause analysis

Root cause analysis is an important methodology in determining the cause of an incident, accident or problem. Several methodologies are available, including 5-whys, fish bone and Apollo, to perform root cause analyses for investigating and identifying problems and for developing appropriate preventive actions. Oilfield equipment is rigorously tested and validated. However, failures leading to an incident or accident still happen for various reasons, such as severe service, inadequate material selection, manufacturing discrepancies or quality control...

Wirelines

On 13 October, the US House Subcommittee on Energy and Mineral Resources hosted a hearing to discuss the draft of the ONSHORE Act, which would enable states with established permitting and regulatory programs to seek responsibilities for oil and gas development on federal lands within their borders. IADC President Jason McFarland issued a public statement of support for the act: “Handing permit oversight over to the states helps to avoid costly duplicative regulation, allowing quicker access to the natural resources that power the US and mean so much to every person in the nation. Currently, the BLM processes these applications in 250-plus days. Conversely, states are able to issue permits within 30-45 days. These delays are costly and detrimental to an industry that contributes a significant amount of revenue and jobs to the US economy. IADC is supportive of the ultimate goal of this legislation to ensure efficient and timely approval of permits and continued US energy independence.”...

HSE&T Corner: Supervisors should seek to understand internal, external factors that influence employee behaviors affecting safety

Performance management and feedback play a critical role in developing and instilling a safety culture within a company. Too often, however, when an incident occurs, supervisors and managers forget that behavior does not occur in a vacuum, Michael LeBlanc, Consultant Manager for Intertek, said on 17 October at the 2017 IADC Human Factors Conference in Galveston, Texas. “When we think of performance management, we have to take into account what goes into an employee’s decisions,” he said. Understanding both the internal and external factors that influence an employee’s thinking and decisions can help a supervisor learn to change how they think about and approach safety...

LWD sonic sensor technology can complement wireline CBL evaluation to validate top of cement

Evaluation of cement placement is an important part of the majority of deepwater wells. Cement placement confirmation is a critical step following the cementing operation. More than one technique can be used to provide information about the top of cement (TOC) and the depth interval of a good bond between the formation and the casing. Determining the length of annular cement coverage, which is an indication of correct cement placement, is useful knowledge before drilling and/or completion operations can proceed...

Drilling & Completion Tech Digest

Weatherford has launched the AutoTong system for automatic pipe makeup and autonomous evaluation of connection quality using high-resolution data. The system eliminates or reduces many of the inefficiencies associated with manual makeup of casing and completion strings. By automating the final makeup sequence with a proprietary speed-control algorithm, speed is automatically adjusted when approaching the optimum torque, eliminating the sudden stops caused by traditional valves...
