• Increase of shale gas drilling in recent years has resulted in a number of claims
• Higher costs and technical difficulties associated with shale gas drilling have increased
both the amount of claims and value of those claims
• Claims can arise from:
• Ruptured drill pipe
• Loss of well bore integrity
• Increased difficulty of controlling the well
• Fracking COW incidents can result in significant claims due to the higher costs of
associated equipment
• Typical Care, Custody, and Control sub-limits can be insufficient due to the increased
quantity and cost of equipment required

• Shale oil is generally produced with salt water.
• Fiberglass tanks are being utilized for storage.
• Corrosiveness of salt water eats away at steel tanks
• Less expensive
• Fiberglass more resistant to electricity
• API Research Report 545A--Verification of lightning protection
requirements for above ground hydrocarbon storage tanks

Saltwater Tanks & Lightning Claims
15. #IRMI2017
• Claims are occurring even with lightning protection.
• Flowing salt water generates static electricity in fiberglass tanks
• When lightning storms are in the vicinity, this creates are stronger attraction
for the lightning than normal.
• Hydrocarbon Vapor on top of the salt water in the tanks provides fuel for
fire/explosion.
• More fiberglass tanks/more saltwater being produced
• More claims being generated

Abandonment Case Study
Contractor agreed to plug the well for $47,980.
Commenced operations in September and finished same month.
In December, Texas Railroad Commission (TRRC) inspects well and
identifies pressure in the well at the surface.
Operator is called back out to correct P&A work.
Other Contractors are called to assist, and well is finally plugged for a total
incurred cost of $982,344.
Our insured is notified of their alleged liability due to “damage to the
wellbore” of some dropped tubing into the casing.

The saying is “If you don’t get rid of pressure when you start
deep, you won’t get rid of it later on.”
Plugs are set at bottom and crews work up the hole in
succession

2.3 Sources of Stray Gas
Stray gas found in a water well or in a home may originate from various sources. The primary source
is pre-existing, shallow deposits of natural gas, which is described in section 2.2.1. Other sources
include:
• Underground activities unrelated to shale gas production (e.g., coal
mining, landfills),
• Leaks from abandoned, recently drilled, or operating gas wells, or
• Leaks from natural gas pipelines or natural gas storage fields or
caverns.
In any investigation of stray gas, it is important to evaluate and identify the actual source of the
methane so the appropriate remedial actions can be taken.

37. #IRMI2017
Presentations illustrated the technical complexities
involved in some stray gas investigations and the
importance of:
• thorough assessments of site geology,
• the need to evaluate the full range of potential
methane sources, and
• the value of using compositional gas analysis to
complement isotopic analyses.

38. #IRMI2017
Incidents of alleged stray gas often require evaluation
of multiple potential sources.
The source of stray gas may be the result of a
• natural condition or
• due to a variety of anthropogenic activities, or a
• combination of both.
Incidents can manifest as non-threatening or as a
significant threat to public safety.

Stable Isotope Analysis and Interpretation
Many of the presenters showed data that used stable
isotopes (or isotopic analysis) to help characterize and
distinguish methane from different sources through
“fingerprinting”. The next few sections provide a brief
introduction to the subject.
When the isotopic signatures of different samples
are plotted on a graph, their relative positions,
when used in conjunction with other analytical
methods, may help investigators or researchers to
differentiate gas that originated from different
sources (K. Revesz).

Case Law Update
49. #IRMI2017
• First Texas Bank (“FTB”) asked Chris Carpenter to investigate a roof leak in its roof. Carpenter had been FTB's “go-to guy” for roof repairs for
years. After his initial inspection, Carpenter informed FTB the building had hail damage. In connection with its insurance claim, FTB asked
Carpenter to show the insurance adjuster the hail damage. Carpenter and the adjuster used one of Carpenter's ladders to ascend to the
first tier of FTB’s roof and used one of FTB's ladders to access the second tier. In the process of descending from the second tier, Carpenter
fell, crushing two vertebrae.
• Carpenter filed suit against FTB and asserted the ladder was defective. In connection with its defense, FTB sought the protections afforded
by Chapter 95. Chapter 95.003 provides, in part:
• A property owner is not liable for personal injury... to a contractor, subcontractor, or an employee of a contractor or subcontractor who
constructs, repairs, renovates, or modifies an improvement to real property... unless:
• (1) the property owner exercises or retains some control over the manner in which the work is performed... and;
• (2) the property owner had actual knowledge of the danger or condition... and failed to adequately warn.
• Carpenter asserted Chapter 95 was inapplicable because he did not have a contract with FTB and was therefore not a “contractor” as
required by Chapter 95. The trial court granted FTB's motion for summary judgment. The intermediate court of appeals reversed the trial
court.
• The Supreme Court of Texas began its analysis by noting Chapter 95 did not define the term “contractor.” Thus, it recognized the generally
accepted definition as a “party to a contract.” The Carpenter court then turned its attention to Chapter 95's applicability. In undertaking this
inquiry, the court noted Chapter 95's applicability does not hinge on whether the agreement for the work to be done is written, formal or
detailed. Rather, its applicability turns on the type of work to be done. Based on this analysis, the Carpenter court determined Carpenter
was a “contractor” for purposes of Chapter 95 because he was FTB's roofing contractor. Chapter 95 is only applicable, however, to
contractors, subcontractors, and their employees who “construct[ ], repair[ ], renovate[ ], or modify[ ] an improvement to real property.” It
does not apply to one injury apart from such work.
• The court concluded that because the record was unclear as to whether FTB hired Carpenter to perform work covered by Chapter 95 at the
time of his injury. Therefore, the case was remanded back to the trial court for further proceedings.
First Texas Bank v. Carpenter
50. #IRMI2017
• In Ineos USA, LLC v. Elmgren, the court was presented with two primary issues: (1) whether Chapter 95 applies to negligence claims other than premises liability
(Elmgren asserted a negligent undertaking claim in the trial court) and (2) whether the protection afforded by Chapter 95 extends to a property owner's agent or
employee.
• Ineos USA, LLC owns a petrochemical plant in Alvin, Texas. Johannes Elmgren worked as a boilermaker for Zachary Industrial, an independent contractor that
provided services at the plant. Elmgren was injured in June 2010 while replacing a vale on a furnace header. At the time Elmgren was injured, both Ineos and
Zachary employees conducted a lockout-tagout procedure to isolate the section where the valves Elmgren was replacing were located. A “sniff test” was conducted
an indicated no gas was present in the section. As Elmgren and a co-worker were removing the second valve, a burst of gas exploded out of the pipe, resulting in
burns to his torso, neck, and face.
• Elmgren and his wife filed suit against Ineos and Jonathan Pavlovsky, an employee he alleged was the “furnace maintenance team leader.” Ineos and Pavlovsky filed
motions for summary judgment asserting Elmgren's claims were barred by Chapter 95. Elmgren asserted Chapter 95 did not apply to the claims against Ineos and
Pavlovsky and was not entitled to its protection because he was not a “property owner.” The trial court granted the summary judgments. The intermediate court of
appeals affirmed in part and reversed in part.
• After the intermediate court of appeals issued its opinion, the Supreme Court of Texas issued its opinion in Abutahoun v. Dow Chemical Co., 463 S.W.3d 42, 50 (Tex.
2015), holding that Chapter 95 applied “to all negligence claims that arise from either a premises defect or the negligent activity of a property or its employees by
virtue of the ‘condition or use’ language in section 95.002(2).” Thus, the trial court was correct in applying Chapter 95 to all of Elmgren's negligence-based claims.
• The second part of the court's analysis focused on whether the protection afforded by Chapter 95 extended to Pavlovsky, Ineos's employee. Pavlovsky asserted the
intermediate court of appeals erred in holding that Chapter 95 did not apply to him based on the language in Abutahoun that it applies “to all negligence claims
that arise from either a premises defect or the negligent activity of a property owner or its employees.”
• The court first looked at whether Pavlovsky was entitled to protection as a “property owner.” Section 95.001 defines a “property owner” as “a person or entity that
owns real property primarily used for commercial or business purposes.” The Elmgren court concluded that because Pavlovsky did not own the real property where
Elmgren was injured, he was not a “property owner” as defined.
• The court next examined whether Pavlovsky was entitled to Chapter 95's protections as Ineos's agent. Because Chapter 95's definition of “property owner”
contained “no language including agents who act on behalf of or hold themselves out as the property owner,” the Elmgren court concluded its protections did not
extend to a property owner's agent.
• Finally, the Elmgren court examined Pavlovsky's argument that the term “property owner” must include the owner's employees because otherwise claimants could
circumvent Chapter 95's protections because the employer would ultimately be liable under the doctrine of respondeat superior. This argument was rejected by
the court on the grounds that “Chapter 95 protects a property owner even against claims asserting vicarious liability based on respondeat superior, ...”
Ineos USA, LLC v. Elmgren
51. #IRMI2017
• In TIC Energy & Chem. Co. v. Martin, No. 15-0143 (Tex. June 3, 2016), a Union Carbide employee,
Kevin Martin, lost one of his legs in a workplace accident and recovered workers' compensation
benefits through an owner-controlled insurance program (OCIP) administered by Union Carbide's
parent company, Dow Chemical Company. Because Union Carbide was protected by the worker's
compensation bar to suit, it could not be sued. Martin thus sued TIC Energy & Chemical Company,
a subcontractor providing maintenance services at the facility, alleging TIC's employees
negligently caused his injury.
• Defense argued that TIC should share in the worker's compensation bar as a fellow employee
because it was a participant in the OCIP pursuant to Labor Code Section 406.123, providing that a
subcontractor and its employees are employees of the general contractor if workers'
compensation insurance is provided for the subcontractor's employees. Martin argued that Labor
Code Section 406.122(b), providing that a subcontractor and its employees are not employees of
the general contractor when, as occurred in this matter, it is operating as an independent
contractor and has entered into a written agreement with the general contractor that evidences a
relationship in which the subcontractor assumes the responsibilities of an employer for the
performance of work. The trial and appellate courts both sided with Martin.
TIC Energy & Chem. Co. v. Martin
52. #IRMI2017
• Carpenter remanded back to trial court because “record unclear as to whether
FTB hired carpenter to perform work covered by Chapter 95.” It will be necessary
to determine (1) whether an agreement, written or oral, was in place, and (2) was
the injured party in the course of performing the work provided for in the
agreement.
• Elmgren concluded that Chapter 95 protections do not extend to a property
owner’s agent “who act on behalf of or hold themselves out as the property
owner” so this allows claimants to circumvent the protections by asserting claims
against individual employees.
• Both opinions provide openings for plaintiffs to assert Chapter 95 is not applicable as an
affirmative defense or avoid its applicability all together.
• Court held that subcontractors who opt to participate in an owner’s or general
contractor’s OCIP are now given protection of the worker’s compensation bar
from suits by OCIP holder’s employees.
Key Take-aways
53. #IRMI2017
On the Horizon
• Pascal Ray predicts that the energy industry will see a wave of claims in the near future because of deferred and delayed
maintenance, upgrades and integrity testing of a company's crucial assets of wells, pipelines and refineries. “The downturn in
the [oil] industry has forced cutbacks in maintenance and asset integrity testing, which is most likely going to manifest itself
in asset integrity-related claims,” he says.
• Those strained resources, says Ray, also can cloud executives’ judgment when it comes to crafting the policies that protect
their business: “Many companies can't afford to buy the insurance coverage they need, forcing risk managers into difficult
decisions based on survivability,” he says. Clients, however, still need the proper coverage, whether it's a drain on their
finances or not — and agents may see this market's current environment as an opportunity. Extremely thorough
underwriting and asking the right questions of the client are critical for survival in this market. Increased competition has led
to a soft rate environment in the energy marketplace, with more players — but not always ones that possess a deep bench of
expertise.
•
The soft market created by this increased competition may continue to soften into the near future except in the midstream
sector (transportation and storage entities, such as pipelines, oil tankers and storage systems), where rates may flatten, says
Ray. The U.S. and Canadian midstream sector has been hit with an “unusually high” number of large pipeline losses this year,
he says, which has caused more stringent underwriting and rating of these accounts.
• “More risk exists now than ever before,” Ray adds. “One thing all companies can do to reduce the uncertainty of one of their
greatest risks — asset integrity — is to focus resources on the maintenance and testing of their assets to help prevent them
from becoming the next member of the billion-dollar claims club.”
Note oily skim atop fluid in open topped tank. Some might think a closed tank would be the simple solution but this would allow gases to collect inside the tank. There are safer ways to remove excessive gas from a well. A gas buster some distance would help.

No cement is placed (1) across the perforations nor (2) across the 13-3/8” casing shoe. This lack of a barrier means flow from gas/oil below can rise to infiltrate fresh water zones and worse, reach the surface and pollute the ocean. Speaking of improperly plugging, we were called into to evaluate a plugged well in South Texas where the low budget vendor put plug after plug even though gas was noted throughout.
The solution was to drill out the ineffective plugs and start over-mainly with a deep plug at considerably more expense.
1-Can the source of gas become sufficiently definitive to tie the gas from the water well with the gas flared 2 days earlier from the gas well?
a. this would require extensive geologic correlation, difficult as no gas samples were collected in either instance.
2-how could the plaintiff make their case?
a. SOLUTION: focus on improper cement jobs of subsurface casing, improper communications violating standard practice, reasonable practice, API standards, or even OSHA regulations.
My last slide…John.. This meeting elucidated the potential for isotopic signatures of different samples to help identify the SOURCE of the stray gas. It is a complicated problem and one fraught with potential for much debate.
3.4.1 What Are Isotopes?
Isotopes are different forms of an atom that have slightly different atomic mass due to the presence of one or more extra neutron particles. To use hydrogen as an example, the most common form of the atom is referred to as hydrogen or 1H. It has an atomic number of 1 and has one proton and no neutrons. Other forms of hydrogen occur with one neutron (deuterium or 2H) and two neutrons (tritium or 3H). The carbon atom in methane also has alternate isotopic forms. The common carbon is 12C, but isotopic forms 13C and 14C are also found.
Other atoms also have isotopes that have been used in geochemical analyses. For example, strontium, and oxygen isotopes can help distinguish samples when the carbon and hydrogen information is inconclusive.
