Seadrill orders two high-spec jackups for delivery in 2015 and 2016

Posted on 20 June 2013

Seadrill Limited has entered into contracts for the construction of two high-specification jackups at Dalian Shipbuilding Industry Offshore (DSIC Offshore) in China. The newbuild rigs are scheduled for delivery during Q4 2015 and Q1 2016. The total project price per rig is approximately US $230 million, including project management, capitalized interest, drilling and handling tools, spares and operation preparations, with tail-heavy payment terms.

The two new units will be based on the F&G JU2000E design, with water depth capacity of 400 ft and drilling depth of 30,000 ft. Seadrill now has eight jackups in total under construction at DSIC Offshore of which two are scheduled for delivery in 2013, five in 2015 and one in 2016.

“These two additional orders highlight our commitment to growing our high-specification jackup fleet.  The jackup market has traditionally been a shorter-term market; however, we expect longer-term contracts to be executed going forward.  In addition to increased terms, we expect to see rising dayrates as attrition accelerates amongst an aging global fleet,” Fredrik Halvorsen, CEO of Seadrill Management, said. “These two new orders will increase Seadrill’s jackup fleet to 29 units and strengthen our position as the largest operator of modern high specification drilling units.”

UK HSE report: Reportable hydrocarbon releases nearly halved over three years

Posted on 14 June 2013

The UK oil and gas industry has achieved a 48% reduction in the number of reportable hydrocarbon releases over three years, the annual Health & Safety report published on 13 June by Oil & Gas UK found. The study also showed that the oil and gas sector has the third-best performance in the UK in terms of non-fatal accidents, with a better safety record than the public sector and the retail and general manufacturing sector. “This year’s Health & Safety report shows that the industry’s unwavering commitment to continuous improvement in the safety of offshore workers is bearing fruit,” Oil & Gas UK’s health and safety director Robert Paterson said.

Other findings of the report included:

• A noticeable and steady reduction in the incidence of over-three day injuries to an all-time low;

• No fatalities and a reduction in combined fatal and major injury rates, and in all types of dangerous occurrences; and

• An all-time low in Level 3 verification non-compliances that relate to performance standards of safety-critical equipment identified by an independent competent person.

“In all this progress, our industry’s safety organization, Step Change in Safety, has played a leading role, and most of the improvement is down to the focused, collaborative effort of companies, workforce representatives, trade unions and the Health and Safety Executive in Step Change,” Mr Paterson said. “However, there is no room for complacency. While the review that followed the Piper Alpha disaster provided the foundation for what is now one of the most robust offshore health and safety regimes in the world, the approaching 25th anniversary of that tragedy only serves to remind us that we must never stop at striving to make things safer. Continued engagement of all parties through Step Change in Safety will be crucial in that effort.”

Unconventionals lead the way for drilling automation, but business model defines uptake

John de Wardt, president of DE WARDT AND COMPANY, says the drilling sector’s business model based on dayrates hampers the rate of adoption of automation. Mr de Wardt moderated the SPE/IADC Drilling Systems Automation symposium earlier this year and will moderate a panel discussion at the Business Solutions for Drilling Automation workshop on 18 June in Istanbul.

By Katie Mazerov, contributing editor

Industry’s ongoing efforts to bring automation to the drilling sector will progress over time as a “natural alignment” occurs among the various players, with unconventional developments serving as the impetus for change, a Shell executive contends. “While we see significant opportunities in utilizing automation to improve drilling efficiencies, there is a lack of natural alignment to move it forward,” said Jeff Wahleithner, vice president, global unconventional wells for Shell. “As the industry develops further, the business opportunities for automation will become more obvious, and it will happen, as it has in other industries. It’s a matter of time.”

Mr Wahleithner will be among five presenters in a panel discussion at the Business Solutions for Drilling Automation workshop on 18 June in Istanbul. The event, which is being held in advance of IADC World Drilling 2013, is sponsored by the IADC Advanced Rig Technology (ART) Committee and the SPE Drilling Systems Automation Technical Section (DSATS). Registration can be completed here.

“Shell is pursuing automation to improve safety and efficiency,” he said. “The industry is going through a step-change with the unconventional plays, as massive resources are now recognized as potential developments. These developments will require a high intensity of manpower and equipment. Automation is a critical tool to address these challenges and continuously improve the efficiency.”

That intensity is manifested by the fact that unconventional production requires a large number of wells, with repetitive drilling techniques that lend themselves to automation. “Relative to most conventional operations, the number of wells required to increase production in unconventionals is significant,” Mr Wahleithner continued. “The overall efficiency of the well construction dominates the economics for unconventional developments.”

Joining Mr Wahleithner on the panel will be Jay Minmier, 2013 IADC vice chairman and president of Nomac Drilling; Hege Kverneland, corporate vice president and chief technology officer, National Oilwell Varco; Miguel Angel Fernandez, director, vertical market chemical industries for Siemens; and Mikael Larsson, robotics manager, ABB Turkey. Their presentations will be followed by a group discussion.

The panel will be moderated by John de Wardt, president, DE WARDT AND COMPANY. Mr de Wardt agrees that unconventionals will be a driver of change, but he also says the drilling sector’s business model that is still based on dayrates is impeding the transition. “A new demand for highly efficient, repetitive drilling for unconventionals creates an environment where adoption of automation will bring benefits,” he said. “But the rate of adoption of automation in drilling is hampered by the current business models, not the technology application.”

“Right now, the industry is very fragmented so that when we go to drill a well, we have an array of different pieces of equipment and services,” Mr de Wardt continued. “In order to enable automation, there needs to be integrator for bringing data together and moving data between the multiple sensors and various pieces of equipment into a closed-loop system so it can operate autonomously. At the same time, the business model needs to change to drive the rewards for applying integration and automation.”

Mr de Wardt also contends the drilling industry remains far behind industrial automation, including autonomous mining systems with remote control, as demonstrated at a DSATS/ART symposium held in Amsterdam in March. “This application gap provides an opportunity to accelerate the adoption of automation, which is our reason for bringing outside speakers to the debate.”
