horizontal gravel productivity

Open-hole applications testing multi-zone

In shallow, deviated or long horizontal wells, Weatherford's expandable sand screens can be an alternative to open-hole gravel pack. Expandable Sand Screens, or ESS, is the primary expandable completion technique in Weatherford International 's suite of slotted expandable tubulars that was developed from a concept originally identified in 1993.Web

Productivity Decline Mechanisms in Gravel Packed Perforations

In a cased hole gravel pack completion, perforations are packed with proppant to both mechanically support the perforation cavity, and to filter any produced sand before it reaches the surface. Poor perforation packing sometimes occurs in which the perforation is partially or completely unsupported, leading to earlier productivity …Web
