Methods of producing hydrocarbons from unconsolidated sand formations

A method of producing hydrocarbons from a subsurface formation comprising:

• drilling an uncompleted lateral wellbore with coiled tubing at balanced pressure, wherein:
• the subsurface formation comprises unconsolidated sand,
• the subsurface formation comprises hydrocarbons, and
• the subsurface formation overlays a water-saturated reservoir;
• introducing particles having an average particle size of from 8 mesh to 140 mesh into the uncompleted lateral wellbore, thereby supporting the uncompleted lateral wellbore and avoiding wellbore collapse;
• installing a screen in a vertical wellbore fluidly connected to the uncompleted lateral wellbore, wherein the screen has a mesh size of from 325 mesh to 1000 mesh;
• and
• producing hydrocarbons from the subsurface formation,
• wherein installing the screen in the vertical wellbore comprises installing the screen at a casing opening between the vertical wellbore and the uncompleted lateral wellbore, the uncompleted lateral wellbore being without any casing or liner installed.
