Fracking Education

We’ve tried to provide a fair amount of resources to start educating your self.  We try to provide both Pro’s and Con’s.  Most sites that are listed as a “Pro” will be sites that are maintained and paid for in some sort of manner by the Oil & Gas industry.  Most sights listed as a “Con” will be sights that attempt to challenge the information put out by the Oil & Gas industry and highlight some of the other effects caused by drilling beyond the technicalities of the “Hydraulic Fracture” Process.  Anything listed in the Independent/Non-biased section are generally just news reports that present the facts of things that have occurred, or do a good job of presenting both the good and bad aspects.

Statistics for the number of truck loads it takes to support drilling a well and conduct fracking.

The typical big rig 18 wheel truck load can weigh up to 80,000 pounds.  There will be literally 1000’s of trips per well, per frack.  Each well site can support up to 18 fracks.  Anadarko is proposing 32 wells in our area. If the max of 18 fracks per well occurs – were talking 576 distinct drilling activities.  Here is the break down of truck loads it takes to establish one well and drill one horizontal fracture.

Table 1:Low and High estimates of typical # of truck loads
Load Cargo Low High
Rig Mobilization, Site prep, Demobilization
Drill Pad and Road Construction Equipment 10 45
Drilling Rig 25 30
Drilling fluid and materials 25 50
Drilling Equipment (casing, drill pipe, etc) 25 50
Completion Rig Mobilization/Demobilization 10 15
Well Completion
Completion fluid and materials 10 20
Completion equipment (pipe, wellhead) 5 10
Hydraulic fracture equipment (pump trucks, tanks) 150 200
Hydraulic fracture water 400 1300
Hydraulic fracture sand 20 25
Flowback water removal 200 300
Well production equipment 5-10 5 10
Total(one way) 885 2055
Total(to/from trips) 1770 4110
Table 2: Estimates of total # of truck loads per well completion
Well configurations Low High
1 Well – 1 Frack (To/From trips) 1770 4110
1 Well – 18 Fracks* (To/From trips) 30,330 70,920
32 Wells – 1 Frack (To/From trips) 56,640 131,520
32 Wells – 18 Fracks* (To/From trips) 970,560 2,269,440

*Assuming each additional frack won’t need “Drill pad and road construction equipment”, and will already have a “Drilling Rig”, and the “Completion Rig Mobilization/Demobilization will only have to be done once. Each additional frack wil be 840 – 1965 one way loads, or 1680 – 3930 (to/from trips). This is conservative, as over time a well will have to be re-fracked a few times after production has started, and not all well’s will be drilled at the same time, so drilling equipment will most likely have to be brought in again.

Remember these are 24/7 operations and trucks and truck convoy’s will be running as such to support them. (More in a week than we’ll typically see in a year – and more in one year than we’ll typically see in a lifetime). This is not counting the truck operations that will run perpetually until the well runs dry.

Some stats on the fluids needed to frack a well.

A typical well will use anywhere from 2.4 to 7.8 Million gallons (on average 4.5 Million Gallons per well) of water in addition of up to 900 other chemicals per frack.  The Oil & Gas companies like to highlight that they use types of chemicals found in the cabinet under your kitchen sink. If 98% of the fracking fluid is water and sand and that is 2.4-7.8 Million gallons.  That’s means 48,000 to 156,000 gallons of harsh chemicals make up that other 2%.  When the Oil and Gas companies say that only 0.5% of those chemicals are lethal, that translates to 12,000 to 39,000 Gallons.  Remember this is per frack.  Typically 30-70% of the fluids stay in the ground.

1 acre feet of water = 325,851 gallons of water.
On average 0.3 acre feet of water will support the average families needs for 1 year.
2.4M gallons of water = 7.3 acre feet = Annual consumption of 25 families.
7.8M gallons of water = 24 acre feet = Annual consumption of 80 families.

What this means, is per frack, a well will consume the water that 25 – 80 families would in a year.  A typical frack will only take weeks if that.  Where is all this water going to come from?

How we got some of the stats.
The knowns:

DEC’s 2009 dSGEIS 5.7 estimates the amount of water used per 4000ft lateral wellbore to be 2.4 – 7.8 million gallons — an average of 5.1 million gallons per well.

Maximum allowed truck weight — 80,000 pounds. Average heavy truck weight (empty) — approx. 30,000 pounds

Therefore, a semi-trailer truck can carry a maximum of approx. 50,000 pounds.

50,000 pounds / 8.34 pounds per gallon of water = 5,995 gallons per truckload (max.)

1 million gallons / 5,995 gallons per truck = 167 truckloads

Min: 2.4Mgal = 377 trucks per well + 377 return trips — for a total of 754 trips per well.
Avg: 5.1Mgal = 851 trucks per well + 851 return trips — for a total of 1,702 trips per well.
Max: 7.8Mgal = 1,303 trucks per well + 1,303 return trips — for a total of 2,606 trips per well … Just for the water.
