Today, the International Oil and Gas Producers (OGP) released the Global Industry Response Group (GIRG) reports.  GIRG was formed last July with the goal of better managing offshore safety risks. The organizational structure is illustrated below.

Deepwater Wells: Lessons and Recommendations focuses on the critical prevention programs, and is perhaps the most important of the GIRG reports. Since Macondo, the GIRG team and other industry committees have worked diligently on well planning and integrity issues, and are commended for their outstanding efforts. However, the recommendations presented in the GIRG report are surprisingly modest, and do not reflect the technological and management innovation that industry has demonstrated in pioneering offshore development.  The recommendations fail to break new ground, lack specifics, and, in some cases, appear to be a step backward. In short, the oil and gas industry is capable of much more.  Initial comments follow:

  • Incident data (problem): The absence of comprehensive and verified incident data is one of the “systemic” industry weaknesses identified by the National Commission. OGP has tried to address this problem for years, but has not had the industry-wide support needed to develop a credible program. GIRG has wisely recommended a Wells Expert Committee (WEC) to review selected incident data. However, the recommended program suffers from the same weaknesses that constrain existing OGP reporting programs. OGP must rely on “encouraging” its members to participate voluntarily, and non-members are not included. This type of voluntary program was not good enough before Macondo/Montara, and is certainly not good enough now.
  • Incident data (solution): Industry and regulators need an ironclad commitment that all operating companies will submit incident data in accordance with defined protocols. Contractor data must be included. Companies should execute binding agreements with OGP, or some other entity, to provide this information. The data must be managed by a completely independent entity that cannot, in any way, be directed by an industry advocacy group. Regulators and other independent representatives should be included on the management committee. Regulators should prohibit companies that don’t agree to submit these data from from operating within their jurisdictions. A comprehensive incident reporting and data management system is long overdue, and continued delays are not acceptable.
  • Montara: While GIRG is supposedly in response to both Macondo and Montara, the latter seems to have been largely ignored. The deepwater theme does not apply to the Montara platform, which was in only 80m of water. Despite the post-Macondo focus on water depth, shallow water was arguably a more significant contributing factor to the Montara blowout (batched completions using a cantilevered jackup, mudline suspensions, and two-stage platform installation) than deep water was at Macondo. Also, well capping, which was feasible and ultimately successful at Macondo, could not even be attempted at Macondo because of the manner in which these platform wells were suspended. Finally, GIRG  ignores the special gas migration and kick detection issues associated with horizontal completions like Montara, and the relief well rig availability and release issues that were never fully addressed during the Montara inquiry.
  • Emergency worldwide notification system: In conjunction with the incident reporting system, industry needs an emergency notification procedure that goes beyond safety alerts and requires the immediate attention of every operator and wells contractor. During the Montara inquiry, worldwide attention should have been drawn to the inability of the Montara operator to identify a hydrocarbons influx through the shoe track and into the production casing. Could an effective notification system have prevented Macondo? No one can say for sure, but the probability of a blowout at Macondo would have been greatly reduced if key BP and Transocean personnel had participated in discussions about Montara and the importance of proper negative pressure tests.
  • Dependence on regulator: On page 21 of the report, GIRG recommends that a company “carry out a more extensive programme of self-audit” when there is a lack of competent regulatory oversight. An operator should never depend on the regulator to verify its well or management programs, and should never relax its programs regardless of the level of regulation. Detailed regulatory reviews of specific drilling or management programs are never a substitute for operator diligence. Did the operators at Montara and Macondo rely on the regulator to protect them from themselves? Read the official investigation reports and make your own judgement.
  • Best practices: GIRG recommends “refraining from using the term ‘best industry practice’ until this definition is clarified; we prefer ‘good oilfield practice’ for the time being.”  Isn’t the clarification of best practices the role of groups such as this and industry standards committees? This attitude explains some of the technical recommendations in this report which may be “good oilfield practices,” but fail to raise the bar for safety achievement. Would you be satisfied with “good” if  family members were working on rigs or if operations were conducted off your coast? While “best practices” vary depending on the conditions and circumstances, it’s industry’s responsibility to identify those practices, and industry and regulators must set the bar high and keep raising it.
  • GIRG recommends established practices: Some of the GIRG recommendations, such as the “two-barrier” policy have been standard practice for most operators for years.
  • API RP 75: There are numerous endorsements of RP 75 as an important reference for management systems covering the design of wells and other activities.  RP 75 was a reaction to an MMS regulatory initiative 20-years ago to impose safety management requirements on offshore operators. BP, Transocean, and PTTEP had management systems that were generally consistent with the guidance in RP 75. GIRG needs to go beyond RP 75 and focus on improvements that will make safety management systems more effective.
  • API Bulletin 97, Well Construction Interface Document (WCID): Despite the complete absence of public attention, this is perhaps the most important post-Macondo initiative. It’s thus particularly disappointing that this document is now five months late. How does GIRG recommend the use of a document that is not complete and has not yet (to the best of my knowledge) even entered the balloting process? Another recommended and highly important document, updated RP 96 – Deepwater Well Design, has also yet to be finalized.
  • BOP recommendations: Nothing new or innovative is offered by GIRG. The report calls for 2 shear rams, but only one need have sealing capability, which means that the Deepwater Horizon stack met the GIRG specification. While many BOP advances require additional study, some (such as real-time function and pressure monitoring systems) already exist. Other GIRG technology recommendations are rather timid and generally in the form of suggestions for future study (e.g. study cement bond log technology).
  • Training: This section of the report is good, but doesn’t address deficiencies identified in the Montara inquiry and reviews of historical blowout data. Montara and other accidents have demonstrated that senior rig personnel may have limited understanding about well planning and construction practices. These topics are not covered in well control training programs. How does industry plan to address this major deficiency? While well planning is the responsibility of the operator (often a separate group than is represented on the rig), well control decisionmaking requires a fundamental understanding of well construction practices.  Also evident in the Montara testimony was the total absence of understanding on the part of operator, drilling contractor, and cementing personnel about the historical causes of blowouts. The cementers at Montara were unaware that gas migration/influxes during cementing operations were a leading cause of blowouts. Training programs need to be expanded to provide for the discussion of past accidents and how they could have been prevented.

…but the only Atlantic area included in the present 5-year oil and gas leasing program  is the cross-hatched wedge in the map below.  This area was to have been considered for leasing  in Sale 220, but the sale was cancelled following the blowout. The House Natural Resources Committee has passed legislation that would require that sale to be held.

No matter what happens, Sale 220 isn’t much to get excited about, especially if the Department of Defense has its way. In light of world events and the fuel demands of our military, one would assume that DOD would be a leading advocate for offshore energy exploration and development. However, rightly or wrongly, preventing disruptions to military training and operations has always been a higher DOD priority than domestic energy production.

With regard to Sale 220, DOD wants 72% of this already small area (magenta) removed from consideration. So even if this lease sale is held, the maximum offering would likely be the cross-hatched blue micro-sliver. That would be the extent of Atlantic leasing for the foreseeable future.

Oil is where you find it, not where you wish it was, where it is most convenient, or where you legislate it to be. Ditto for natural gas. We need an offshore oil and gas program that identifies the most prospective targets, provides for exploratory drilling to evaluate these targets, facilitates production, and effectively manages the safety and environmental risks. We can’t just explore the small slivers that remain after political and administrative reviews have eliminated the rest.

Like it or not, our Outer Continental Shelf lands belong to the entire nation. We need to manage these lands and the associated resources in a manner that is in the best interest of all Americans.

CNN Poll

A CNN/Opinion Research Corporation survey released Tuesday indicates that 69 percent of Americans favor increased offshore drilling, with just over three in ten opposed. That 69 percent is up 20 points from last June, while the oil spill was still in progress, and is back to the level of support seen in the summer of 2008.

Confidence in government has shown a less significant increase.

John Milne Book Launch

John C Milne

“Dubs” is a term used in Aberdeen and northeast Scotland to describe all varieties of mud. That is the first thing I learned in reading John Milne’s excellent book “DUBS, How the Oil Came North.”  John’s first job in the offshore industry was with a drilling mud supplier back in 1969 when he was still a college student.  John presents a series of amusing and informative anecdotes about hie work experiences between 1969 and 1973 during the early years of North Sea offshore exploration. The book is available through the publisher, PlashMill Press. Good read!

I also recommend Bjørn Vidar Lerøen’s excellent book “Drops of Black Gold,” which

Drops of Black Gold - Statoil

chronicles the history of Statoil and Norwegian offshore oil and gas development. The book includes a now famous 1962 letter from Phillips Petroleum to the Norwegian government. In the letter, Phillips seeks exclusive rights to the entire Norwegian continental shelf in return for conducting a seismic survey program. Hey, nothing wrong with asking! 🙂

from SeabedRig.com

Advances in drilling technology tend to be evolutionary, not revolutionary. Floating rigs, dynamic positioning, top-drive systems, measurement-while-drilling, automated rig floors, and other important advances were logical next steps, not radical makeovers.

Many of us have long been fascinated by the possibility of locating drilling equipment on the seafloor, particularly for deepwater wells. Why operate from a massive floating vessel that requires a sophisticated stationkeeping system and a long riser to connect to the wellhead? Why link surface personnel to seafloor risks? Why increase the complexity of balancing well pressures (without fracturing formations) by adding thousands of feet to the mud column? Why heave and roll on the surface when you can operate from the seafloor?

It’s not that easy, of course, and there are many questions and issues. While fully automated drilling systems are no longer a reach, what about reliability and repairs?  How will casing be set and cemented? How will downhole measurements be transmitted to the control center? Cuttings samples? Coring? Well testing? The list of challenges is daunting.

At least one company, Seabed Rig, is committed to developing and demonstrating seafloor drilling technology. Earlier this month, Seabed Rig reached agreement with NASA to create the first autonomous drilling rig. While a lot of work remains, Seabed Rig and other pioneering companies are applauded for their innovative thinking and willingness to challenge conventional practices and wisdom.

Bahamas Petroleum, the oil and gas exploration company with licences in The Bahamas, is pleased to announce that the company has completed the acquisition of 1120 km of long-cable (8km) 2D seismic in its southern licences.  The new seismic survey has confirmed the presence of multiple prospects, some of which are 4-way closure in nature and some of which are combination stratigraphic-structural traps.

I’ll defer to the geologists regarding the significance of this announcement, but the results would seem to provide further encouragement for the island nation’s exploratory drilling plans. Will Florida politicians try to bully the Bahamas the way they have been bullying Cuba?

Well, well. In early March, Cuba will commence with deep water drilling under contract with Repsol and Statoil ASA, using an older rig that was recently rehabbed by the Chinese. Reports indicate that it has fewer safety features than the BP’s infamous Deepwater Horizon. The site is located a scant sixty miles southeast of Key West, Florida. Benzinga.com

There are some  errors and unsupported opinions in this article, so I would take the March spud date with a grain of salt.  As confirmed by Rigzone, the Saipem Scarabeo 9 is a new rig, not a rebuild. It was built in China and commissioned in Singapore. The inflammatory comment about the rig having fewer safety features than the Deepwater Horizon is also without substance. Everything about the Scarabeo 9 appears to be state-of-the-art.

While a projected 2011 spud date has been reported and appears likely, Cuba’s deepwater drilling program has been marked by repeated delays. BOE has seen no confirmation that the rig has arrived or is en route to Cuba. We would appreciate any updates that others might be able to provide.

Shell has agreed to transport its used drilling fluids from Beaufort Sea exploration drilling out of the Arctic if the company finally gets government permission to drill a well next summer. Alaska Journal of Commerce

I assume this includes all drilling fluids and drilled solids (cuttings) except for the spud mud and cuttings generated prior to installing the riser?  If so, I believe this will be a first for an exploratory well drilled from a floating rig in US offshore waters.
