The second form shows the long distance communication between injectors and producers that are characterised by strong responses above the predefined level. Results indicate very good short and long distance communication between injectors...

In December 1969, a high pressure crestal gas injection program was implemented to improve the oil recovery. Better performances were observed in the gas-swept Zone (GSZ)., therefore water injection...
