16. Is There Enough Water to Expand
Development of the Eagle Ford
Shale?
And the answers are:
Water Yes – required volumes exist in the region
Fresh groundwater No
supply concerns where drilling intensity is high in rural counties.
fresh groundwater may not always be where it is needed
W D Hall Company Austin, Texas 16
17. Who directly impacts the availability of
groundwater for E&P operations?
Land Owners
Groundwater Conservation Districts (GCDs)
Railroad Commission
W D Hall Company Austin, Texas 17
19. The water Sheriff is the General Manager of the
local Groundwater Conservation District
And the District Board of Directors
A water well used solely to supply water to a
drilling rig for oil and gas is exempt from obtaining
a drilling permit from the GCD
Big question – Is a frac water supply well exempt?

20. What are they?
Desired future conditions are the desired,
quantified condition of groundwater resources
such as:
water levels

22. Options
Onsite treatment for reuse/recycling of flowback
and produced water
Use of alternate water supplies
Non-water hydraulic fracturing options
Opportunities to be smart, cost effective and develop good
relationships with local communities

23. Onsite treatment for reuse/ recycling of
flowback and produced water
Railroad Commission has permitted a number of
Mobile Produced Water Treatment Companies for
work in the Eagle Ford
Treatment choices
For reuse (clean brine/TSS removal (some blending with
fresh groundwater) – reuse in fracs
For recycling (clean water/TSS and TDS removal); sold for
other uses?
W D Hall Company Austin, Texas 23
24. Onsite treatment for reuse/ recycling of
flowback and produced water
General water management expenses for E&P operations
Clean water supply acquisition costs
Water supply transport cost
Pipeline costs
Vacuum trucks to remove waste water
Trucks cost to transport produced water to SWD well
SWD well fees
E&P operators are paying $3-$8/bbl to convert produced
water to clean water + acquisition, storage and transportation
costs
W D Hall Company Austin, Texas 24
25. Onsite treatment for reuse/ recycling of
flowback and produced water
Pros
Lower water acquisition costs
Reduced disposal costs
Reduced use of fresh water
Reduced environmental impact from transport and disposal
Fewer truck trips
Former waste stream becomes part of supply chain
Adding water to the hydrologic system!
Cons
COST - If fresh groundwater is abundant and locally available from water
wells, treatment and reuse / recycling is not usually economical
Increased environmental risks from additional site treatment operations
W D Hall Company Austin, Texas 25
26. Use of alternate water supplies
From municipal wastewater system to industry – Crystal City,
Pleasanton, Kenedy, Poth,
From industrial wastewater systems to other industry users –
San Miguel Electric Coop, Gonzalez Southern Clay
Before either municipal and industrial wastewaters are used for hydraulic fracturing,
the transaction will need authorization from TCEQ.
Brackish groundwater – Is being used!
Brackish groundwater has 1000 to 10,000 mg/l TDS.
Both brackish and saline water (> 10,000 mg/l TDS) can be used for hydraulic
fracturing.
Brackish groundwater is plentiful in many parts of Texas.
W D Hall Company Austin, Texas 26
28. Non-water hydraulic fracturing options
Providers and users in the Eagle Ford
GasFrac Energy Services, Inc. – uses liquefied petroleum gas (LPG) instead of water
Chimera Energy – exothermic reactions instead of water, metal oxides create heat that expands and
cracks the shale
Baker Hughes – VaporFrac uses CO2 or nitrogen instead of water
eCORP Stimulation Technologies - uses propane (Frio County)
Users - Blackbrush Oil & Gas and Jadela Oil
Pros – water conservation; reduce costs for water wells; more compatible with formation’s gas;
quicker completions with no flowback water; wells can be placed into production faster; fewer
additives required; reduced formation damage; cost saving where water isn’t available; helps lift
reservoir fluids; no clay swelling; allows more gas to escape.
Cons – LPG cost – 50% premium over traditional fracking companies;; Safety compared to water
fracs? Potential for the propane to ignite; TBD. Closed pressurized (nitrogen) system, hot zone;
smaller jobs than water fracs; open hole vs plug and perf; logistics of NGL delivery; fluid availability.

Thank you.Fresh groundwater is the primary source of water supply for hydraulic fracturing operations in the Eagle Ford Shale in South Texas. Here’s the problem – Why should we pump up to 9 million gallons from the Carrizo aquifer, use it one time, and inject it into a deep salt water disposal well?This doesn’t make sense to me. Not when there are good alternatives. My goal is to find ways to “Stretch Out” the fresh water resources in Texas.
The Eagle Ford Shale underlies approximately 25 counties in South and Southeast Texas at depths to the top of the producing zones ranging from 4,000 to 14,000 ft. It stretches for about 400 miles from Laredo into East Texas. The subsurface reservoir is about 50 miles wide. Here is San Antonio, Houston , Corpus Christi, and Laredo.
Here is an interesting view of the Eagle Ford Shale boom from space!This night picture shows gas flares and lights from the recent and ongoing drilling operations.
Here is a sprinkling of headlines about water in Texas over the past 3 years. Even In the early days - all the way back to 2011 - The concerns and issues were about groundwater availability.
In 2012 the researchers began to see that hydraulic fracturing was using more groundwater than previously expected.Jobs in Eagle Ford related towns were a plus. Irrigation was beginning to get a lower priority in some places.
2013 has started out with a call to Legislators for help with the Texas water situation.The drilling has picked up and recognition of the need to for more communication about use of groundwater is growing.
Location – San Antonio, Corpus Christi, LaredoCities in the development area – Carrizo Springs, Asherton, Big Wells, Catarina, Cotulla, Dilley, Christina, Tilden, Kenedy, Karnes City, Three Rivers, Gonzalez, Advantage – Oil, wet gas (condensate) and dry gas
The number of future wells to be drilled in the Eagle Ford varies widely!The University of Texas Bureau of Economic Geology is evaluating the number of wells that can be expected in the Eagle Ford Shale. This figure shows some of the assumptions that are part of the forecast.The drainage area is roughly 50 to 60 acres.Ultimately the number of wells at a single pad – a lot!
This drilling plan by Rosetta Resources for the Eagle Ford may be easier to visualize. This still shows lots of wells requiring lots of water!Each requires 4 to 9 million gallons of fresh water or an alternative for placing the proppant and cracking the brittle shales.One question - Will these wells be fractured and then fractured again a couple years later?
The big question – Is there enough water to expand development of the Eagle Ford Shale? I think there is. But there are a lot of players and priorities to consider including increased population, competing users, and the ongoing drought.I recommend that operators get to know the local Regional Water Planning Group supported by the TWDB. South Texas has Regions L, M and N. These groups will develop the water use policies. Regional Water Planning Groups can and will impact development of the Eagle Ford Shale I also recommend that operators look for ways to “stretch out” freshwater resources in the development areas, i.e., look for alternatives
Here is a map of the Texas Water Development Board’s Regional Water Planning Groups (RWPGs).Region L is right in the center of the Eagle Ford Shale development area and is one of the 16 regional water planning groups established by the Texas Water Development Board (TWDB) to develop a regional water plan as required by Senate Bill 1, 75th Legislative Session.
The primary water policy planning group in the South Texas Eagle Ford Area is Region L.20 and ½ CountiesParticipants include members representing: Counties; the Public; Water Districts; Industries; River Authorities; Small Business; Environment groups; Electric Generating Utilities; Water Utilities; Municipalities; and, Agriculture. And TWDB.
The water planning process usually begins with a projection of future population in the areaThe population of the South Central Texas Region was 2.04 million in 2000 and is projected to be 4.3 million in 2060. More people means increase municipal water supply needs.As you can see, the Region L planners anticipate municipal water supply shortages in the future. The shaded counties are projected to have needs exceeding supply.
Irrigation is already a big user in the area and will continue to be. Consideration of these factors and forecasts is the responsibility of the Regional Water Planning Groups. Source – Strain on water resources
The ongoing drought is a real problem and concern in South Texas.2010 – Not much of a problem2011 – Exceptional and extreme drought in South Texas2012 – Still the most extreme drought conditions through much of the Eagle Ford Shale development area
A number of water supply analyses have been completed and presented.Railroad Commission Eagle Ford Task Force report on water availability In a recent study by the Bureau of Economic Geology for the TX O & G Assoc., the researchers found that in Dimmit, Webb, and LaSalle counties – all in the Eagle Ford Shale – more than 50% of total water use is mostly for hydraulic fracturing.Population growth will accompany and be accelerated by development of oil and gas resources. If population growth is desirable, solutions must be found for managing water to enable continuing hydrocarbon production.
What to the GCDs do?Develop a groundwater management planPlanning is mandated by Chapter 36 of the Texas Water CodeRegulation is optionalSome of the Goals of the Groundwater Management PlanEfficient use of GWPrevent wasteAddress drought conditionsAddress conservationThey estimate the amount of usable GW availableAddress water supply needs developed by the RWPGCoord with RWPGs, State Agencies, and other GCDs
Oversees the management of the DistrictPermit and register certain water wells; Maintain well recordsMay limit groundwater production based on tract size or spacing of wellsMay buy and sell, transport and distribute GWMay acquire land by use of eminent domainMay conduct surveys, do research or establish monitoring programsMay require permits for transfer of GW out of the District
The DFCs are a consensus reached among the general managers of the GCS within a larger groundwater management area based on groundwater modeling conducted by the TWDB.These DFCs could very well limit the amount of fresh groundwater available for E&P operations.Desired future conditions have to be physically possible, individually and collectively, if different desired future conditions are stated for different geographic areas overlying an aquifer or subdivision of an aquifer.
This flowback and produced water is usually very salty and unsuitable for disposal in lakes, rivers or aquifers. Therefore it is often trucked to SWD wells. The amount of truck traffic going in and out of a drilling location is high – as many as 1000 to 1500 trips in with fresh water and 200 to 300 trips out to the disposal well. Research by AWI and GWI revealed that that in the US, beneficial use accounts for approximately 200 million bbls per year of all produced water managed by oil and gas companies. The total amount of produced water per year in the US is estimated at 21 billion bbls/yr. The total reused is less than 1% of the total produced.FQ – E&P operators are paying $3-$4/ bbl to convert produced water to clean water.

There is enough water underground to supply Texas for 176 years but it’s too brackish for drinking. 3,000 – 10,000 mg/l TDSApproximately 2.7 billion acre-ft of brackish groundwater exist in Texas (TWDB, 2003). It can be found in 85% of the state’s major and minor aquifers in all 16 RWPGs.However that brackish water – even before treatment - my be fine for hydraulic fracturing operations. (StateImpact Texas, Nov 28, 2011)Brackish GW is attractive for several reasons:The water source is reliable, even during droughtsThe cost of treatment facilities are becoming more competitiveBrackish water treatment facilities can be developed and implemented in relatively short periods of time.The estimated amount of brackish groundwater in Region L is 417 million ac/ft (TWDB)
How Much Produced Water Is Generated? Produced water is by far the largest volume byproduct or waste stream associated with oil and gas exploration and production. Approximately 21 billion bbl (barrels; 1 bbl = 42 U.S. gallons) of produced water are generated each year in the United States from nearly a million wells. This represents about 57 million bbl/day, 2.4 billion gallons/day, or 913,000 m3/day (Clark and Veil 2009).More than 50 billion bbl of produced water are generated each year at thousands of wells in other countries. Early in the life of an oil well, the oil production is high and water production is low. Over time the oil production decreases and the water production increases. Another way of looking at this is to examine the ratio of water-to-oil:Worldwide estimate – 2:1 to 3:1U.S. estimate – 5.1 to 8:1, because many U.S. fields are mature and past their peak production (Clark and Veil 2009), although the ratio may be even higher.Many older U.S. wells have ratios > 50:1At some point the cost of managing the produced water exceeds the profit from selling the oil. When this point is reached, the well is shut in.
The new Texas Water Recycling Association would like to have a say in the debate. - 2013
