Gravity drainage startup using rf & solvent

26) A method of producing a hydrocarbon from a subsurface formation comprising:

• a) forming a solvent vapor assisted gravity drainage production well pair within a subsurface formation comprising an injection well and a production well;
• b) beginning a pre-soaking stage by soaking at least one of the wellbores of the well pair with a solvent, wherein the solvent does not include water;
• c) beginning a pre-heating stage by heating the soaked wellbore of the well pair with a radio frequency device to produce a solvent vapor;
• d) beginning a squeezing stage by introducing the solvent vapor into the soaked wellbore of the well pair;
• and
• e) beginning the solvent vapor assisted gravity drainage production when said well pair are in thermal communication.

28) A method comprising:

• a) forming a solvent vapor assisted gravity drainage well pair within a formation comprising:
• i. an injection well;
• and
• ii. a production well;
• and
• iii. wherein the injection well is vertically spaced proximate to the production well;
• b) beginning a pre-soaking stage by soaking at least one of the wellbores of the well pair with a solvent, wherein the solvent does not include water;
• c) beginning a pre-heating stage by heating the soaked wellbore of the well pair with a radio frequency device wherein the radio frequencies emitted from the radio frequency device are optimized to heat the solvent and the connate water in the formation into a solvent vapor;
• d) stopping the heating of step (c) and continuing a squeezing stage where the wellbore exists at a higher pressure as a result of solvent vapor introduction in step c);
• and
• e) beginning the solvent vapor assisted gravity drainage production.
