3-D and 4-D Siesmic
3-D mapping is a computer generated map that shows not only latitude and longitude but depth as well. It Is used to find rock formations that are likely to conlain oil or natural gas.
4-D mapping is similar to 3-D but uses many surveys over time to monitor movements of gas and fluid underground. This is done by overlaying multiple data sets and tracking the differences over time.

Fracturing
Hydraulic fracturing (called TMfrac Jobs,( 1 )(2) “frac’ing,”(3) frackIng,(4) or Hydrofracking) is a process that results in the creation of fractures in rocks. The fracturing Is done from a weilbore drilled Into reservoir rock formations to increase the rate and ultimate recovery of oil and natural gas.
