Introduction
• Rapid development of the
Marcellus and Utica
shales led to big demand
in Class II disposal wells.
• There are a limited
number of Class II SWD
wells in NY, PA, and WV.
• Ohio remains well suited
for handle the increase in
disposal activity.

Ohio’s Class II SWD Program
• Ohio received primacy of its
Class II program in 1983.
• Ohio has seen a dramatic rise
in Class II SWD permitting
activity since 2010.
• Class II wells have increased
from 161 to 238 permitted
wells.
• Currently, there are 202 in
operation, 17 being drilled or
completed and 22 permitted.

Increased Ohio Injection Activity
•
•
•
In mid-2010, with the enactment of Senate Bill 165, Ohio started tracking brine
disposal on a quarterly basis and in-state vs. out of state disposal volumes.
Disposal volumes in Ohio have continued to increase from a little over 12.5
million barrels in 2011 to over 23 million barrels in 2014.
Out-of-state disposal reached a peak of 58% in 2012 and has now leveled off to
about a 50/50 split, with the marked increase in disposal from Ohio’s Utica Shale
operations.

…..And New Regulations
• Ohio has passed several
rounds of new regulations
since 2010 that have
impacted Class II SWDs concerning well
construction and
cementing, seismic
monitoring, additional
injection well testing
requirements, and
continuous integrity
monitoring.

•
•
•
•
•
•
•
•
•
•
•
•
Finding and locating open spaces for well siting.

Well Siting Criteria
• Ideally, away from
populated areas.
• Good road network
and access.
• Purchasing or leasing
property, mineral
rights issues, rights to
inject.
• Favorable geologic
conditions for high
capacity disposal.

Geological Evaluation
• Proper geological
evaluation is critical to a
successful large
capacity disposal well in
Ohio.
• Knowledge of geologic
formations and regional
variations is important
in selecting appropriate
disposal intervals.

Working with Regulatory Agency and
Permitting Process
• Completion of the area of
review evaluation.
• Submittal of required
applicant forms.
• Fulfillment of public notice
requirement.
• Addressing of potential
objections to the
application.

Opposition to Injection Wells
• Opposition to saltwater
disposal wells has
increased dramatically in
Ohio in the last three
years.
• There have been
objections to SWD
applications and protests
and demonstrations at
operational sites.
• The applicant needs to be
prepared to address these
challenges.

Well Construction, Cementing, and
Completion Practices
• Understanding proper
well construction design,
geophysical log
interpretation, cementing,
and completion practices
in Ohio are essential to a
successful SWD well.

Additional Ohio Downhole Testing
Requirements
• Additional testing
requirements such as
radioactive tracer or
spinner survey logging.
• Pressure fall-off tests.
• Testing and recording
original bottom hole
pressures.
• Any other tests the
Chief deems necessary.

Seismic Unit Installation
• Ohio regulations can
require submittal of a
seismic monitoring
plan.
• Seismic unit installation
is now required on deep
Knox – Mt. Simon Class
II SWD wells.
• Agreed seismic unit
locations with ODNR

Actual Seismic Monitoring
• Seismic monitoring in
real-time.
• Required to submit
data to DOGRM.
• Notification to
operator of seismic
event in real-time by
automated e-mail.

Typical Injection Surface Facility
Operation in Ohio
• Two types of surface
facilities are common –
earthened dike with
minimum of 30 mil liner
or concrete dike.
• Dike must be able to
contain all fluids in event
of accidental release.
• Concrete unloading pad
with drain and sump that
collects any spillage is
required.

Pre-treatment of Injection Fluids
• It is extremely important to
properly filter and
chemically treat the
injectate prior to injection.
• Chemical treatment needs
to address not only the type
of fluid to be injected, but
also the sensitivity of the
injection formations.
• Advanced technology
applications can offer
additional alternatives and
cost savings.

TENORM and Solid Waste Disposal
in Ohio
TENORM in Ohio is regulated by
the Ohio Dept. of Health (ODH).
Oil and gas regulations also address
requirements for testing or
manifesting of TENORM solid
wastes.
Radium-226 and Radium-228 are
the predominant TENORM issues
with oil and gas.
At Ohio Class II SWD facilities, solids
required to be tested for TENORM
will be tank bottoms, pipe scale,
and filter media.
These solids can also be manifested
for shipment out of state without
conducting testing.

TENORM Regulations in Ohio
• Ohio has some of the
most stringent TENORM
rules in the country.
• Ohio landfills can only
accept TENORM wastes at
concentrations of less
than 5 picocuries per
gram above background
radiation.
• Regulations allow for
dilution of TENORM
wastes with approval
from Ohio Dept. of
Health.

Conclusions
• Proper consideration of
these challenges can
lead to success in Ohio’s
SWD environment.
• ALL is actively engaged
in assisting oil and gas
clients in Ohio and
understands how to
maneuver in the
disposal well landscape
and how to address
these challenges.
