Horizontal Well - Overview, How It Works, and Uses

A horizontal well is a type of multi-directional drilling technique that drills with an inclination of at least 80 degrees to enhance reservoir performance. The horizontal technique is used as an alternative method for drilling oil and gas in situations where vertical wells are impossible or the shape of the reservoir is difficult to access.

Analysis of Inflow-Control Devices | SPE

Inflow-control devices (ICDs) were developed to avoid water-coning problems in long horizontal wells. The model for the ICD consists of pressure-drop equations from the reservoir, through the screen, the flow conduit, the ICD nozzle, and into the production tubing, along with pressure drop through the lower-completion system.

Drilling and completion improvements support Permian Basin ...

Operators continue to drill longer horizontal segments, or laterals, for wells in the stacked reservoirs of the Delaware Basin and Midland Basin. The share of wells with 11,000-foot or longer lateral segments increased from less than 1% in 2014 to around 20% in 2021 across the entire Permian Basin.

12 - Horizontal Well Completion | Pump | Gas Technologies

Horizontal Well Completion Horizontal well (HW) drilling is potentially the most important completion technique since hydraulic fracturing HW is normally drilled vertically to a particular depth and horizontally to additional hundreds or thousands feet HW is classified based on its turning radius R = 57.3/BUR (buildup rate, o/ft) Three types ...
