Speaker Biography Ted Johnson is the Chief Hydrogeologist at the Water Replenishment District of Southern California He manages projects related to groundwater recharge water quality and seawater intrusion for the Central Basin and West Coast Basin in southern Los Angeles County Lately he has been investigating potential impacts to groundwater quality from petroleum practices and hydraulic fracturing in the WRD service area since the LA Basin has a long history of both hydrocarbon and groundwater production Ted has over 26 years of experience in hydrogeology and has a BS in Geology and a MS in Enviroinmental Studies from the California State University at Fullerton He is a licensed Professional Geologist and Certified Hydrogeologist and is the Vice President of the Groundwater Resources Association of California

Hydraulic Fracturing and Groundwater A Los Angeles Water Districtrsquos Perspective

By Ted Johnson Chief Hydrogeologist Water Replenishment District of Southern California West Coast Landmenrsquos Institute ndash September 5 2013

Hydraulic Fracturing (ldquoFrackingrdquo or ldquoFracingrdquo)

Has helped expand oil and natural gas production in the US to highest levels in decades and could supply the country for gt 100 years

Has unlocked large supplies of hydrocarbons in shale and other unconventional formations in many States providing energy jobs and revenue

But as fracking grew so did world-wide concerns about possible environmental impacts

What is Hydraulic Fracturing

Method to enhance oil or natural gas production Has been done at smaller scales for decades

Inject fluids (water sand chemicals) under very high pressure to break and keep open rock to make oil and gas flow

Improvements in horizontal drilling technologies have led to significant increase in fracking for oil and gas in the United States

Vertical and Horizontal wells and Fracking

9

Conventional vs Unconventional Conventional Fracking in permeable reservoirs like sandstone and limestone to improve flow to wells Has been for gt 50 years Vertical or slant wells Lower pressure and water Common in CA and elsewhere

httpwwwgeomorecomshale-gas-and-fracking

High-Rate Gravel Packing Small scale fracking near the well bore to install gravel pack to improve flows at the oilgas well andor to prevent formation sand entry (like a gravel pack in a water well)

Unconventional Newer drillingfracking in hard tight source rock that is porous but not permeable (ie shale) ldquoHigh Volume Frackingrdquo TX PA ND WY MO CO OH Extensive in CA too

10

Injection Fluids for Fracking Water Average 5 million gallons per job for high volume unconventional lt 300000 for conventional lt 100000 gravel pack Propane and butane being explored to replace water in water-short areas ldquoDry Frackingrdquo

SandSilica (proppant) keeps fractures open otherwise would close

Assorted chemical additives are site specific Many purposes inhibit corrosion remove drilling mud prevent scaling reduce viscosity etc

httpfracfocusorgwater-protectiondrilling-usage 11

Acidizing Matrix Acid Jobs and Fracture Acidizing

Another method to open up tight or clogged formations and improve hydrocarbon flow to wells

Matrix acidizing at relatively low pressures to dissolve sediments mud and carbonates near the well

Fracture acidizing at higher pressures to break open rock and create new fractures and dissolve minerals to improve permeability

Use of hydrochloric acid (HCL) and hydrofluoric acid (HF) common

Why Frack Create a new energy resource Unconventional drilling and fracking now accounts for more than half the natural gas production in the US Estimated over 100 year supply

Allows extended production in older oil and gas fields

Allows recovery of petroleum from tight formations previously thought unproductive

Reduced price of natural gas

Hydraulic Fracturing has been done for over 50 years New ldquoHigh Volume Unconventionalrdquo methods are proving very fruitful but controversial worldwide

Summary

Fresh groundwater oil and natural gas have been successfully produced in the CBWCB for over 100 years

The two reservoirs are separated by thick layers of low permeability strata so that with appropriate precaution construction regulation and monitoring the activities in one should not affect the other

WRD continues working with regulatory agencies on appropriate fracking rules We donrsquot want to hamper the energy industry we just want to ensure protection of the groundwater resource Both can be done successfully

What is Hydraulic Fracturing

Method to enhance oil or natural gas production Has been done at smaller scales for decades

Inject fluids (water sand chemicals) under very high pressure to break and keep open rock to make oil and gas flow

Improvements in horizontal drilling technologies have led to significant increase in fracking for oil and gas in the United States

Vertical and Horizontal wells and Fracking

9

Conventional vs Unconventional Conventional Fracking in permeable reservoirs like sandstone and limestone to improve flow to wells Has been for gt 50 years Vertical or slant wells Lower pressure and water Common in CA and elsewhere

httpwwwgeomorecomshale-gas-and-fracking

High-Rate Gravel Packing Small scale fracking near the well bore to install gravel pack to improve flows at the oilgas well andor to prevent formation sand entry (like a gravel pack in a water well)

Unconventional Newer drillingfracking in hard tight source rock that is porous but not permeable (ie shale) ldquoHigh Volume Frackingrdquo TX PA ND WY MO CO OH Extensive in CA too

10

Injection Fluids for Fracking Water Average 5 million gallons per job for high volume unconventional lt 300000 for conventional lt 100000 gravel pack Propane and butane being explored to replace water in water-short areas ldquoDry Frackingrdquo

SandSilica (proppant) keeps fractures open otherwise would close

Assorted chemical additives are site specific Many purposes inhibit corrosion remove drilling mud prevent scaling reduce viscosity etc

httpfracfocusorgwater-protectiondrilling-usage 11

Acidizing Matrix Acid Jobs and Fracture Acidizing

Another method to open up tight or clogged formations and improve hydrocarbon flow to wells

Matrix acidizing at relatively low pressures to dissolve sediments mud and carbonates near the well

Fracture acidizing at higher pressures to break open rock and create new fractures and dissolve minerals to improve permeability

Use of hydrochloric acid (HCL) and hydrofluoric acid (HF) common

Modified from Dallas Society of Petroleum Engineers dallasspeypcompresentationsAcidizingPresentationppt

WaterMud

Why Frack Create a new energy resource Unconventional drilling and fracking now accounts for more than half the natural gas production in the US Estimated over 100 year supply

Allows extended production in older oil and gas fields

Allows recovery of petroleum from tight formations previously thought unproductive

Reduced price of natural gas

Creates jobs in energy industry

Summary

Fresh groundwater oil and natural gas have been successfully produced in the CBWCB for over 100 years

The two reservoirs are separated by thick layers of low permeability strata so that with appropriate precaution construction regulation and monitoring the activities in one should not affect the other

WRD continues working with regulatory agencies on appropriate fracking rules We donrsquot want to hamper the energy industry we just want to ensure protection of the groundwater resource Both can be done successfully

What is Hydraulic Fracturing

Method to enhance oil or natural gas production Has been done at smaller scales for decades

Inject fluids (water sand chemicals) under very high pressure to break and keep open rock to make oil and gas flow

Improvements in horizontal drilling technologies have led to significant increase in fracking for oil and gas in the United States

Vertical and Horizontal wells and Fracking

9

Conventional vs Unconventional Conventional Fracking in permeable reservoirs like sandstone and limestone to improve flow to wells Has been for gt 50 years Vertical or slant wells Lower pressure and water Common in CA and elsewhere

httpwwwgeomorecomshale-gas-and-fracking

High-Rate Gravel Packing Small scale fracking near the well bore to install gravel pack to improve flows at the oilgas well andor to prevent formation sand entry (like a gravel pack in a water well)

Unconventional Newer drillingfracking in hard tight source rock that is porous but not permeable (ie shale) ldquoHigh Volume Frackingrdquo TX PA ND WY MO CO OH Extensive in CA too

10

Injection Fluids for Fracking Water Average 5 million gallons per job for high volume unconventional lt 300000 for conventional lt 100000 gravel pack Propane and butane being explored to replace water in water-short areas ldquoDry Frackingrdquo

SandSilica (proppant) keeps fractures open otherwise would close

Assorted chemical additives are site specific Many purposes inhibit corrosion remove drilling mud prevent scaling reduce viscosity etc

httpfracfocusorgwater-protectiondrilling-usage 11

Acidizing Matrix Acid Jobs and Fracture Acidizing

Another method to open up tight or clogged formations and improve hydrocarbon flow to wells

Matrix acidizing at relatively low pressures to dissolve sediments mud and carbonates near the well

Fracture acidizing at higher pressures to break open rock and create new fractures and dissolve minerals to improve permeability

Use of hydrochloric acid (HCL) and hydrofluoric acid (HF) common

Why Frack Create a new energy resource Unconventional drilling and fracking now accounts for more than half the natural gas production in the US Estimated over 100 year supply

Hydraulic Fracturing has been done for over 50 years New ldquoHigh Volume Unconventionalrdquo methods are proving very fruitful but controversial worldwide

Summary

Fresh groundwater oil and natural gas have been successfully produced in the CBWCB for over 100 years

The two reservoirs are separated by thick layers of low permeability strata so that with appropriate precaution construction regulation and monitoring the activities in one should not affect the other

WRD continues working with regulatory agencies on appropriate fracking rules We donrsquot want to hamper the energy industry we just want to ensure protection of the groundwater resource Both can be done successfully

Acidizing Matrix Acid Jobs and Fracture Acidizing

Another method to open up tight or clogged formations and improve hydrocarbon flow to wells

Matrix acidizing at relatively low pressures to dissolve sediments mud and carbonates near the well

Fracture acidizing at higher pressures to break open rock and create new fractures and dissolve minerals to improve permeability

Use of hydrochloric acid (HCL) and hydrofluoric acid (HF) common

Why Frack Create a new energy resource Unconventional drilling and fracking now accounts for more than half the natural gas production in the US Estimated over 100 year supply

Allows extended production in older oil and gas fields

Allows recovery of petroleum from tight formations previously thought unproductive

Hydraulic Fracturing has been done for over 50 years New ldquoHigh Volume Unconventionalrdquo methods are proving very fruitful but controversial worldwide

Summary

Fresh groundwater oil and natural gas have been successfully produced in the CBWCB for over 100 years

The two reservoirs are separated by thick layers of low permeability strata so that with appropriate precaution construction regulation and monitoring the activities in one should not affect the other

WRD continues working with regulatory agencies on appropriate fracking rules We donrsquot want to hamper the energy industry we just want to ensure protection of the groundwater resource Both can be done successfully

Hydraulic Fracturing is used for Water Wells Too

httpwwwnhcontractorsnet201201hydrofracking-nh

49

Hydraulic Fracturing has been done for over 50 years New ldquoHigh Volume Unconventionalrdquo methods are proving very fruitful but controversial worldwide

Summary

Fresh groundwater oil and natural gas have been successfully produced in the CBWCB for over 100 years

The two reservoirs are separated by thick layers of low permeability strata so that with appropriate precaution construction regulation and monitoring the activities in one should not affect the other

WRD continues working with regulatory agencies on appropriate fracking rules We donrsquot want to hamper the energy industry we just want to ensure protection of the groundwater resource Both can be done successfully

Summary

Fresh groundwater oil and natural gas have been successfully produced in the CBWCB for over 100 years

The two reservoirs are separated by thick layers of low permeability strata so that with appropriate precaution construction regulation and monitoring the activities in one should not affect the other

Fresh groundwater oil and natural gas have been successfully produced in the CBWCB for over 100 years

The two reservoirs are separated by thick layers of low permeability strata so that with appropriate precaution construction regulation and monitoring the activities in one should not affect the other

WRD continues working with regulatory agencies on appropriate fracking rules We donrsquot want to hamper the energy industry we just want to ensure protection of the groundwater resource Both can be done successfully

Fresh groundwater oil and natural gas have been successfully produced in the CBWCB for over 100 years

The two reservoirs are separated by thick layers of low permeability strata so that with appropriate precaution construction regulation and monitoring the activities in one should not affect the other

WRD continues working with regulatory agencies on appropriate fracking rules We donrsquot want to hamper the energy industry we just want to ensure protection of the groundwater resource Both can be done successfully
