handling (associated wastes)
![Page 4: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/4.jpg)
Most Exploration and Production (E&P) Wastes Are Nonhazardous Wastes
EPA decisions in 1988 and 1993 States have regulatory authority
over E&P wastes Some generic industrial wastes
are hazardous Solvents, paint wastes, etc.

Estimates of Offshore Drilling Waste Disposal Costs from
Operators 1997 estimate was about $10/bbl plus
transportation and cleanup costs ~$20-30/bbl
1998 data shows wide range of costs most companies - $10-$50/bbl several companies from $100-$418/bbl
![Page 15: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/15.jpg)
Disposal Cost Estimates - continued
during the recent SBM rulemaking, several operators submitted current cost data to EPA
most extreme was Unocal that cited actual data from 1997-1998 average cost of onshore disposal for 10
wells = $710/bbl average cost of injection for 11 wells =
$318/bbl overall average cost for 21 wells = $430/bbl
![Page 16: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/16.jpg)
Basis for Unocal Estimate ratio of disposed
volume to cuttings volume for 5 wells 1,741 bbl cuttings
generated 15,223 bbl muds and
cuttings disposed 17,447 bbl washwater 19:1 cuttings to total
disposed volume

Synthetic-Based Muds Offer Strong Drilling Performance and Low Environmental Impacts
![Page 21: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/21.jpg)
Types of Drilling Fluids water-based muds
(WBMs)
oil-based muds (OBMs)
synthetic-based muds (SBMs)
![Page 22: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/22.jpg)
Advantages of SBMs performance
comparable to or better than OBMs
low toxicity muds are recycled some deepwater
wells cannot be drilled without SBMs
![Page 23: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/23.jpg)
Disadvantages of SBMs
high cost
uncertainty about discharging cuttings
![Page 24: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/24.jpg)
Efforts to Resolve the Regulatory Barrier
1995 - DOE funded study to identify and clarify the problem
DOE established informal synthetic fluids discussion group EPA DOE MMS oil and gas operators drilling service companies
EPA used the group to present information needs for modifying ELGs
![Page 25: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/25.jpg)
EPA’s Decision to Modify Offshore ELGs for SBMs [12/97] Normally need 4-6 years to develop ELG EPA recognized environmental benefits from
SBMs decided to use “expedited rulemaking”
approach proposed rule in 1 year final rule in 3 years
industry provided data to EPA iteratively EPA and other stakeholders met throughout the
process to discuss progress and exchange information and comments
![Page 26: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/26.jpg)
What Has EPA Done?
Final rule 1/22/01 zero discharge of
fluids not attached to cuttings
cuttings discharges allowed with restrictions
![Page 27: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/27.jpg)
Summary SBMs represent an
innovative, cost-effective, and environmentally friendly technology
EPA used expedited rulemaking process to develop new regulations for SBM cuttings discharges
This is a win/win/win situation

Wetlands Restoration Using Treated Drilling Waste –
A Beneficial Reuse of a Waste Product
![Page 38: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/38.jpg)
Wetlands Loss
greatest environmental problem facing coastal Louisiana is the loss of wetlands
oil and gas industry has contributed to the loss
![Page 39: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/39.jpg)
What Can Be Done?
restore damaged wetlands
use solid waste product from oil and gas exploration (treated drill cuttings) as a substrate for restoring wetlands
![Page 40: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/40.jpg)
Background DOE funded Greenhill Petroleum to
conduct studies on using treated drill cuttings to restore wetlands1) laboratory mesocosm studies to assess
growth success Southeastern Louisiana University (SLU)
2) field pilot study near Venice, LA create berm out of dredged material fill inside of berm with treated cuttings plant with wetlands vegetation
![Page 41: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/41.jpg)
SLU Mesocosm Studies 144 200-liter
growth vessels 4 3,000-liter
water supply reservoirs
3 hydrological regimes
four substrates 6 types of
wetlands plants 2 replicates of
each set of conditions

Problems with Permits for Field Pilot Study Greenhill applied for 404
permit EPA wetlands office
generally agreed, but EPA discharge permit office objected disposal of drill cuttings is
subject to NPDES permit NPDES general permit
prohibits discharge of drill cuttings to coastal waters
![Page 45: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/45.jpg)
Argonne Asked to Get Involved formed project team
DOE Argonne SLU SWACO XPLOR Energy
looked for other regulatory mechanisms that would lead to a permit
![Page 46: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/46.jpg)
Project XL Was Only Viable Alternative
EPA Office of Reinvention program allows circumvention of existing environmental rules when applicant can show superior environmental benefits from project
![Page 47: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/47.jpg)
Conclusions the concept of using treated
drill cuttings for wetlands restoration is sound
properly treated cuttings can support good growth
the process reuses a waste product for a beneficial purpose
additional work is needed to get U.S. and foreign regulators comfortable with the concept
![Page 48: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/48.jpg)
Salt Caverns Represent a Cost-Effective and Safe Alternative for Disposal of Oil Field Wastes
![Page 49: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/49.jpg)
The Waste Disposal Process
salt caverns are initially filled with brine
wastes are injected as a slurry of waste and water or brine
the incoming waste displaces the brine which is brought to the surface and either sold or injected into a disposal well
incoming waste
brine
![Page 50: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/50.jpg)
Caverns Act Like Giant Oil/Water/Solids Separators
solids sink to the bottom and oil floats to the top
as wastes fill the cavern, the end of the tubing is raised so that filling can continue.
![Page 51: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/51.jpg)
Cavern Failure Is Most Likely to Occur after Closure
creeping action of salt geothermal heat modeling of liquid-filled caverns
indicates: elevated pressures low likelihood of leaks and failures
solids-filled caverns will be equally or less likely to fail
![Page 52: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/52.jpg)

Disposal Caverns Are Safe for E&P and NORM Waste Disposal even when all caverns
leak, the modeled risks are within or below the acceptable risk ranges
human health risks from cavern disposal of oil field wastes are very low
![Page 54: E&P Waste Management Technologies – One Size Does Not Fit All](https://reader034.vdocument.in/reader034/viewer/2022051419/56815a6b550346895dc7c3b7/html5/thumbnails/54.jpg)
Conclusions cavern disposal of E&P and NORM
waste is technically feasible cavern disposal poses very low
human health risks

What Is Slurry Fracture Injection (SFI)?
Solid material is ground into small particles Pumped into a formation at high pressure
Formation fractures allowing slurry to move into rock

Project Scope1. Identify and describe existing
injection technologies (SFI and other)
2. Identify commercial disposal companies that use SFI
3. Develop database of sites/facilities where SFI of oil field
wastes has occurred

Scope – continued4. Compile directory of state, federal, and
international (where applicable) requirements for SFI Laws, regulations, policies Identify areas where SFI is prohibited
5. Develop information on actual and avoided costs of SFI
6. Prepare report7. Disseminate information through
publications, conference presentations, and workshops (if necessary)

International Perspective
Many developing countries do not have well-established E&P waste requirements or infrastructure
U.S. companies operating there may face limited and costly disposal options Ex: oil-based muds in Mexico must be
managed by thermal desorption Efforts to develop a risked-based framework
for waste management
