1. INTEGRATED SUBSEA OIL HEATING AND PUMPING SYSTEM AND WATER INJECTION FOR RESERVOIR PRESSURIZATION, characterized by comprising:
at least one recoverable pumping module;
at least one producing subsea well through at least one production line which flows produced oil;
at least one injection subsea well through at least one injection line; and
a base that connects a production unit through a riser and an injection line,
wherein injection fluid corresponding to water, from the production unit through the injection line:
hydraulically actuates a pump residing in the pumping module; and
is injected into the injection well, and
wherein the SYSTEM is characterized by further comprising a heating module.
