How is the Well Control Rule different? What changed? What remains the same?

Even though the Well Control Rule has been in effect for nearly six months, there is still a sense of uncertainty among the industry about what needs to be done to be compliant. Our clients, Operators and Lease Holders in particular, are still trying to decipher how the new rules affect their specific operations and what they need to do differently, and reach out to us with questions seeking guidance. Despite the variety of operations, well designs, equipment, and environments, there are common themes. One such theme is understanding, at a high level, what is new vs. what stayed the same.

In a nutshell, the Well Control Rule introduced changes in five specific areas. First, it consolidated requirements that were previously scattered in separate sections. Prior to the Well Control Rule, Title 30 Part 250 of the US Code of Federal Regulations (30 CFR 250) contained three separate sections that described similar requirements for well control equipment under each of the three defined well operation types: Drilling (Subpart D), Well Completion (Subpart E), and Well Workover (Subpart F). The Well Control Rule removed the requirements within each of the sections and consolidated them all into a new Subpart G, which all three operations types (Drilling, Well Completion and Well Workover) must now comply with.

Second, the new rule introduced revised design requirements for Blow Out Preventers (BOPs). Newer (not latest, which is a topic of another discussion) industry standards were incorporated by reference; namely API Standard 53 (replacing Recommended Practice 53) and API Specification Q1, among others. The rule also requires dual blind shear rams with improved shearing capabilities; enhanced control fluid accumulator capacity; locking mechanisms for surface stacks; additional emergency/secondary controls such as ROV Intervention. Not all requirements must be met immediately however, as some have two, three, five, or seven year “grace periods” before enforcement.

Third, the Well Control Rule revised the requirements for operation and maintenance of well control equipment. Instead of allowing stakeholders to choose any independent third party to verify compliance, the BSEE will now qualify, create, and maintain a list of BSEE Approved Verification Organizations (BAVOs). Independent third parties are still acceptable until such time the BAVO List is published, but once the BSEE releases the list, stakeholders are required to use a BAVO that is on the list. If the independent third party of choice is not on the list, the BSEE will reject any verifications or certifications issued, regardless of qualification. BAVOs are also required to issue a Mechanical Integrity Assessment (MIA) report every 12 months, which is separate and different from other inspections (such as certificates to support permits). Lastly, the BSEE requires all failures to be reported in an attempt to bridge the gap between original equipment manufacturers (OEMs) and operational performance. Athens Group wrote an article about this subject in the December 2015 issue of Offshore Engineer Magazine.

Fourth, remote real-time monitoring (RRTM). The requirements for RRTM changed significantly since the rule was first proposed in April of 2015, and now require Lease Holders to develop a real-time monitoring plan when pertinent to enable personnel to monitor operational conditions and equipment status from shore. The National Academy of Science (NAS) Transportation Research Board (TRB) conducted a study including industry workshops (Athens Group was a panelist) that discussed some of industry’s concerns. The main concern is not whether RRTM is feasible, the technology exists, or what benefits it provides, but rather controlling paths to safety critical industrial control systems from potential cyber-attacks. The Oil & Gas Industry does not have a mature cyber-security culture, and there is limited guidance available, (US Coast Guard is working on Cyber-Security Guidelines, but they have not been implemented yet). The potential impact is not limited to loss of financial or sensitive data (e.g., Yahoo accounts being hacked, or the release of customer financial data at Target), but rather degrading operational performance, personnel safety, or environmental consequences from losing control of the equipment (e.g., Stuxnet).

Fifth, and lastly, the shift from “prescriptive regulatory specification” to “prescriptive risk-assessed and performance-based compliance”. The Well Control Rule marks a significant departure from previous regulations that specified “what” was needed in order to be compliant, and instead defines “how” stakeholders can be compliant. Compliance with the regulations is “by intent” and not “by the letter”, granting the flexibility to propose alternate methodologies as long as they are “as safe or better” than what is required (this is the process referred to as Alternate Compliance). The new rule also places a stronger emphasis in promoting safety as a function of quality (a topic Athens Group discussed in our newsletters), exemplified by the adoption of API Specification Q1.

Even though the changes described above are significant, at a high level, the Well Control Rule had no impact from a procedural standpoint. The impact is felt primarily on the supporting documentation and requirements rather than changing the permitting process. Well control equipment still needs to be tested periodically, has to be verified prior to working on a well, and still has to be maintained and recertified by OEM every five years. What changed is how and who is qualified to do so, while the activities remain essentially the same.

How does the Well Control Rule affect my intended operations?

Prior to the Well Control Rule, requirements for well control were scattered among different sections depending on the type of operations conducted. The Well Control Rule consolidated all requirements found in these subparts under one, Subpart G, which is now referenced by other Subparts throughout Title 30, Part 250 of the Code of Federal Regulations (30 CFR 250). In particular:

  • Subpart D, 30 CFR 250.411(f): Oil and Gas Drilling Operations
  • Subpart E, 30 CFR 250.513(b)(4): Oil and Gas Well-Completion Operations
  • Subpart F, 30 CFR 250.613(b)(3): Oil and Gas Well-Workover Operations

Subpart G, 30 CFR 250.731 states: “For any operation that requires the use of a BOP, you must include the information listed in this section with your applicable APD, APM, or other submittal.” Note the term “BOP” is not specific to drilling BOPs, and therefore encompasses all blowout preventers by definition. Moreover, 30 CFR 250.731(c) requires certification pursuant to 30 CFR 250.732, for every application for permit to drill (APD) or application for permit to modify (APM). Despite the consolidation however, the effects of the Well Control Rule can be described from two fronts. Most of the design changes are geared towards equipment primarily used in drilling operations, so we can focus on this side of the industry first.

The incorporation of API Standard 53 by reference was seen somewhat as a relief for those Lease Holders and equipment owners (namely Drilling Contractors) whose assets are relatively new, roughly 5 years old. These assets for the most part were already designed to comply with API Standard 53, thus only those regulatory requirements with a “grace period” are a concern (e.g., enhanced shearing capability and centralizer systems). The newer the asset, the less they are impacted by the new rule. The changes introduced by the rule affect drilling assets that were not operating in conformance with API Standard 53 at the time the rule was published in the Federal Register (since it was not a requirement until now unless contractually agreed). This includes those assets equipped with surface BOP stacks (i.e., BOPs that are installed on the asset itself and not deployed to the seabed) due to the requirement for locking mechanisms on ram-type preventers. In summary, the older the drilling asset, the more likely it will need to be modified to comply with the new regulation.

The second front consists of well completion and workover operations. At first glance, it would seem they are the most affected since they now must comply with the same requirements as drilling assets. This does not mean that a well intervention vessel needs to be equipped with a six-ram BOP Stack. As we explained in a previous answer, the BSEE understands these operations are much more dynamic, requiring a variety of equipment configurations that cannot be forced to be prescriptive in terms of design, so the Well Control Rule is design for “compliance by intent” instead of “compliance by the letter”. Clause §250.701 enables the use of alternate procedures or equipment as long as the intent of the rule is met via a risk assessment to determine whether the proposal “equals or surpasses current BSEE requirements.” Guidance for departure from the regulation is possible via §250.702, but these require stronger justification and will be regarded with higher scrutiny given the relative flexibility of alternate compliance. Therefore, completion and workover assets are in compliance as long as they meet the intent of the Well Control Rule (namely, maintain the integrity of the well and prevent a safety or environmental incident).

What systems does the BSEE Well Control Rule cover?

Despite its name, the Well Control Rule is not limited to well control equipment. Although it is prescriptive about the design, operational and maintenance requirements for Blow Out Preventers (BOPs), the rule actually encompasses all equipment and methodologies used to maintain the integrity of the well and secure the asset in case of loss of control of the well (this is where the BOP fits). Choke Manifolds, Diverters, Riser, Casing Designs, etc. are all included. The rule does not address other systems such as drilling (e.g., Top Drives, Pipe Racking System), power management (e.g., generators, switchboards), with the exception of positioning equipment, particularly if the asset is a mobile offshore drilling unit (MODU).

This may come as a surprise to some, as positioning equipment is not normally associated with well control. The BSEE recognizes the relationship between the ability to maintain the integrity of the well with the asset’s capability of maintaining its position in order to do so. Specific requirements for equipment, inspections and certifications of vessels are stipulated in Title 33, Subchapter N, Part 143 of the US Code of Federal Regulations (33 CFR 143) and are stewarded by the US Coast Guard. However, there are certain provisions required by the BSEE to ensure the asset remains on station to prevent the integrity of the well from being compromised.

What is a BSEE-approved verification organization (BAVO)? What is the current status of BAVOs?

Prior to the Well Control Rule, Operators and Lease Holders had the flexibility to use the independent third party of their choice to provide the certifications, verifications, reports or reviews as required. The BSEE will now populate and maintain a list of organizations that BSEE has qualified and approved to conduct the certifications, verifications, reports and reviews stipulated. BSEE-Approved Verification Organizations (BAVOs) essentially replace the independent third parties, and Operators or Lease Holders are now required to select one from the list when published.

The Well Control Rule includes a list of qualifications that BAVOs must meet to be considered, but specific guidance for qualification and application process are still under development, so no BAVOs exist at this time. The BSEE must first provide public notice of the application process and the specific requirements for qualification, compile a list of approved organizations, and then post the official BAVO list. Operators and Lease Holders are not required to use BAVOs until one year after the list is published; until that time, independent third parties can still be chosen freely as long as they meet the requirements prior to the Well Control Rule going into effect.

When do I need to engage a BAVO?

Until the BSEE publishes a list of BSEE-approved verification organizations (BAVOs), independent third parties must be used to fulfill the activities assigned to BAVOs in the Well Control Rule. The only exception to this is the yearly Mechanical Integrity Assessment (MIA), which is separate and different from the certifications required during the permitting process. Therefore, MIAs are not required until the BSEE publishes the list of BAVOs.

As was the case before the new regulation became effective, BAVOs are required to inspect the condition of the equipment and maintenance history as part of the permitting process for every operation, whether it is drilling, completion, or workover. BAVOs are also required to be present on the rig during major equipment inspections required every five years, and provide a report of the inspection activities and any corrective or remedial actions that were taken. A BAVO must also issue a report whenever any other well control equipment not specifically stated, or whenever redundant components intended for well control are used in addition to those components specified by the rule to ensure the systems are suitable for their intended use, and any failure will not compromise the integrity of the well control equipment.

To support the initiative from the BSEE to close the loop with original equipment manufacturers (OEMs) by providing operational performance data, BAVOs are required to issue a report every time there is a need to repair, replace, or reconfigure well control equipment stating the equipment is fit for service. BAVOs are not required to report the failure or ensure an investigation into the causes of the failure has been conducted (Operators and Lease Holders are required to do this). Some Operators however feel it would be easier to engage BAVOs earlier to let them handle the entire failure reporting process.

Why did the BSEE not incorporate the latest versions of applicable industry standards? Which version should I use for my operations?

BSEE incorporates standards by reference that are available at the time the rule is initially planned and the rule-making process begins, not those available at the time the rules are published. This is why versions for some of the standards that were already released and effective were not incorporated (e.g., eighth edition of API Specification Q1 instead of the ninth edition, which is in effect today). This is how the rule-making process is designed; it lags industry, continuously elevating the minimum operational baseline.

Regulatory requirements supersede industry standards and references unless stated otherwise, so that creates two options:

  1. Ignore the latest standards and operate as per the version incorporated by reference. This is probably the easiest path towards compliance, but stifles improvement opportunities and adoption of new processes that may be safer and more effective.
  2. Follow the intent of the rule, and request alternate compliance if required (by choice or contractual obligation) to use newer versions of the standards. If the new version is “as safe or better” than the version incorporated by reference, this method promotes innovation and ensures your project operates above the baseline. Compliance is no longer a goal, but rather a byproduct of a well-designed operating methodology.
