A method of controlling subterranean placement of underground fluids, such as liquids, includes (a) positioning a tubing joint longitudinally in a borehole in the earth to locate the split and gun at selected depth, (b) rotating the tubing to orient the split azimuthally so that a gun in the tubing is aimed in a desired direction laterally, (c) discharging the gun to cause its projectile to travel in said desired direction in the formation, thereby opening up a lateral shot hole in the formation, (d) and pumping fluid under pressure down the borehole to discharge into the shot hole into a selected zone laterally spaced from the tubing.

The method of controlling the subterranean flow contaminants in water draining from a pond or reservoir, the pond of reservoir also receiving inflow of contaminants, that includes (i) removing settled contaminants at the bottom of the pond or reservoir, and (ii) injecting into the subterranean forma

The method of controlling the subterranean flow contaminants in water draining from a pond or reservoir, the pond of reservoir also receiving inflow of contaminants, that includes (i) removing settled contaminants at the bottom of the pond or reservoir, and (ii) injecting into the subterranean formation a substance that creates a barrier in the formation to said subterranean flow, to thereby block said flow, (iii) said contaminat removal being carried out at a rate in relation to said inflow that contamination by escape of contaminants via subterranean flow, beyond the barrier, is substantially stablized, (iv) said (ii) step including employing a tubing joint having a split in the side thereof, and a gun positioned inside the tubing with a projectile in the gun to be dicharged through the split in the tubing, and including the further steps: (a) positioning the tubing joint longitudinally in a borehole in the earth to locate the split and gun at selected depth, (b) rotating the tubing to orient the split azimuthally so that the gun is aimed in a desired direction, laterally, (c) discharging the gun to cause the projectile to travel in said desired direction in the formation, therby opening up a lateral shot hole in the formation, (d) and pumping said substance in the form of fluid under pressure down the borehole to discharge into the shot hole into a selected zone laterally spaced from the tubing.
