A Technical question. Anyone know when a horizontal well is "fracked" how many meters out from the well is the source rock actually fractured? I realize that it is a complex process and is dependent on the type of rock, pressures, etc., but somewhere in the planning there must be a rule of thumb; ie. 10-20 meters, or 40-50 meters.


For example if a shale deposit is 100 meters thick is it possible to drill down to 25 meters into the shale and frack it to effect the 25 meters above the the well and the 25 meters below the well and of course all around the well. Then on the same pad drill down into 75 meters and frack that to allow oil/gas collection throughout the full 100 meters.
