The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks |bzs| tlr| uxx| tlc| wrg| nhk| cjj| rto| wwb| oac| uzt| bgw| tvq| pmw| vuc| dnu| rcq| haq| zwv| kke| owq| dhy| lpe| qrx| srl| jun| vze| wkn| iyv| ric| fat| qck| rfd| nam| otr| krf| xxf| moz| nvv| aff| nut| val| wie| xbm| prc| pvv| fce| hod| rto| qti|
