A truckload is ~50,000 lbs of proppant. That gives ~1,000,000 lbs of total proppant. The wells with ~5,000 ft laterals are pumping around 4 mmlbs of proppant (~300 ft spacing and ~250k lbs per stage). Mind you that they can't typically fit 4 mmlbs on location at one time so they will pump a stage or two and reload. Meaning, the 20 trucks might have been the initial fill up of the Sand Chiefs on location and not the entire load for the well. So, keep paying attention because more trucks might be coming. If you dont see any more trucks, check your survey and find out how long the lateral is or the perf to perf distance from the scout ticket to see if it was just a shorter lateral which will require less proppant.

Hey Mark, Thanks. I did find out that it ended up around 3.5mm lbs. It was a 4.5K lateral with 16 stage frac.

Same goes for water. I know that CHK will do 1 to 2 stages a day, and refill the water tanks overnight.

It's amazing how they can get that sand into the far reaches without it settling out of the water and clogging up the line.

its called pressure and rate

I understand it's under pressure but how do they keep the sand suspended in the water?

A lot of pressure at a high flow rate. Think of sluicing sand out of the river like they did for those new apartments by Hamels.

Wow, are you guys saying that a "typical" HS well might have 4 million pounds of sand pumped into the ground during fracking?

That's what Questar/Petrohawk are doing. The Questar CEO said in the last conf. call that they were seeing a correlation between IP's and the amount of propant being used. The guy in charge of fracing that I spoke with said that all the wells they had fraced like this were in the 25 - 30 mmcfd range.

This is one of those "I just didn't get it" moments. It always sounded a little hokey that fracking the shale and blowing in a little sand into the cracks would really change flow rates that much. Blowing in 4 million pounds of sand is a lot more than I was thinking. It makes a lot more sense now.

It's usually about 3 to 4 million pounds of prop (man made either ceramic or sand coated with resin) and then close to 1million of 100 mesh which is small very fine sand.
