METHODS OF PRODUCING HYDROCARBONS FROM UNCONSOLIDATED SAND FORMATIONS
A method of drilling an uncompleted lateral wellbore in a subsurface formation includes drilling the uncompleted lateral wellbore with coiled tubing in the subsurface formation. The subsurface formation includes unconsolidated sand and the subsurface formation overlays a water-saturated reservoir. The method may further include 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 and 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. The subsurface formation may include hydrocarbons and the method may further include producing hydrocarbons from the subsurface formation.
Method and apparatus for inflow control with vortex generation
An inflow control device for controlling a production flow can include an inlet, a vortex chamber, and a flow control chamber. The inlet can extend obliquely relative to the central axis of the device. The vortex chamber can induce a vortical inflow from the inlet. The flow chamber can receive vortical inflow from the vortex chamber. A movable restriction disk within the flow control chamber can restrict the vortical inflow therein.

Valve with integrated fluid reservoir
Certain aspects and features of the disclosure relate to a valve device for use in a wellbore. In one example, the valve device includes a body containing swell fluid, a swellable elastomer, and a piston. The swell fluid can contact the swellable elastomer, causing the swellable elastomer to swell. The swellable elastomer can swell and contact the piston. The swellable elastomer can move the piston from a first position to a second position. In the second position, the piston can open, close, or restrict one or more flow paths through the valve device.
METHOD AND SYSTEM FOR MONITORING AND PREVENTING HYDRATE FORMATIONS
A method for monitoring hydrate formation in an interior of a tube may include deploying a first hydrate controller device at a first location on an exterior surface of the tube. The method may include deploying a second hydrate controller device at a second location on the exterior surface of the tube.
