A method of operating an actuator in mud having debris and lost circulation material is described. The method includes closing a servo valve positioned within a valve housing. The valve housing has a plurality of fluid vents positioned downstream of the servo valve and a plurality of debris vents positioned upstream of the servo valve. Dimensions of the plurality of fluid vents are less than dimensions of the plurality of debris vents. Closing of the servo valve creates a first fluid path such that fluid flows from a mud pump at a surface into the plurality of debris vents and out of the plurality of fluid vents shielding the servo valve from debris and lost circulation material.

An in-line treatment cartridge and methods of using same are disclosed. The in-line treatment cartridge can include a cylindrical body configured to allow fluid to flow therethrough and a plurality of particulates contained within the body. At least one particulate of the plurality of particulates can include a chemical treatment agent. The at least one chemical treatment agent can separate from the at least one particulate upon contact with a fluid.

A perforated filtration insert includes a head unit and a body portion having perforated side walls. The body portion is closed at one end by a cap such that fluid entering the body exits through the perforations in the side walls of the insert.

Examples described herein provide a method that includes performing a geomechanical analysis for a wellbore for each of a plurality of sand screens. The method further includes selecting a sand screen from the plurality of sand screens based at least in part on the geomechanical analysis. The method further includes deploying the selected sand screen in a tubular of the wellbore to filter particulate passing through an opening of the tubular.

A well tool assembly can include a well screen configured to filter fluid flow between an interior and an exterior of a tubular string, and an outflow control section that permits the fluid flow in an outward direction and prevents the fluid flow in an inward direction, the outflow control section including at least two outflow control valves arranged in series. A method can include installing a well tool assembly including a well screen, flowing a fluid from an exterior to an interior of a tubular string through the well screen and an inflow control valve of the well tool assembly, and flowing another fluid from the interior to the exterior of the tubular string through the well screen and at least one outflow control valve of the well tool assembly.

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.
