2015 ISP: Fatalities fall from 21 to 8; LTI, recordable incidence rates both down by approximately 20%

The global drilling industry reported eight fatalities in 2015, according to the most recent report from the IADC Incident Statistics Program (ISP). That is a significant improvement over the 21 fatal incidents reported in 2014. In particular, ISP data showed that – for the first time since the program started in 1962 – US onshore drilling contractors reported zero fatalities. “It’s an achievement worth celebrating and shows that all the efforts that onshore drillers have been putting in to improve safety are paying off,” Rhett Winter, IADC Director of Onshore Operations, said.

On 14 July, the US House of Representatives passed H.R. 5538, the Interior Appropriations Act. In response, IADC President Jason McFarland said, “The passage of the Interior Appropriations Act with robust support for oil and gas provisions indicates that House members recognize the tremendous role the energy sector plays in ensuring America’s economic stability. IADC is pleased that the $32 billion measure, which will fund the Interior Department, EPA and other related agencies in fiscal year 2017, contains language that is supportive of oil and gas activities.

With BSEE Well Control Rule in force, it’s time to take another look at RFC-HSE variant of MPD

Drilling techniques associated with closed and pressurizable circulating mud systems have become standard on land drilling programs over the past several decades. This progression can be measured by the growth in rental activity of rotating control devices (RCDs). Because these techniques and technologies have proven effective onshore, greater application in marine environments seems uniquely logical.

Exception-based remote monitoring incorporates intelligence to enable early detection of well control events

Industry statistics suggest that the majority of well control incidents and near-misses occur during well construction operations. To address this issue, the industry has focused on stringent well design and casing standards, blowout prevention equipment, safe drilling practices and multiple layers of workflows and controls. However, the data also shows that most well control incidents occur as a result of human factors – misinterpretation of data, delayed response to abnormal well conditions, drilling crew inexperience and physical fatigue – that are not addressed by hydraulics and mechanical well control mechanisms.

Rig briefs: Robotic arm for automated pipe handling, 20,000-psi riser system, ergonomic driller’s station among industry innovations

The best derrickmen in the drilling business can rack a stand of pipe at an approximate rate of about 20 seconds per pipe at the start of a tour, according to RigArm, a Calgary-based drilling equipment manufacturer. However, fatigue then begins to set in and can affect performance.

Remote directional drilling sets roadmap to industrialization

In 2014, Precision Drilling, Schlumberger and Pason Systems launched an initiative with the aim of industrializing unconventional drilling in North America. Specifically, the companies set out to transform directional drilling by increasing repeatable high-quality results while simultaneously reducing the manpower and time required to drill a well. This collaboration is now coming to fruition, resulting in a remote directional drilling service that uses Precision’s drilling rigs and Schlumberger’s abbl drilling operations adviser service.

When applying new hardbanding on top of worn and cracked hardbanding, there is a risk of incurring additional durability problems. Recently, a Russian offshore drilling contractor’s drill pipe showed signs of wear and traverse cracking with a titanium hardbanding product. Duraband non-cracking (NC) hardband was chosen for re-application, and Hardbanding Solutions Europe was asked to oversee the work of removal, repair of the tool joints and application of Postalloy Duraband NC.
