A SYSTEM AND A METHOD FOR DETERMINING INFLOW DISTRIBUTION IN AN OPENHOLE COMPLETED WELL

摘要

The invention relates to a system and a method for determining flow patterns of fluid in a production well. Especially, the invention relates to a method of determining flow patterns between and into oil production wells drilled in the Earth when flow is improved by water flooding. The system comprises a canister (1) said canister being located in said formation at a subterranean location within or proximate the wellbore, the canister being provided with an exit opening (5), a traceable component (4) being placed in the canister and able to pass through the exit opening and a release mechanism capable of releasing the traceable component when triggered by a triggering mechanism such that the traceable component enters the fluid flowing through the well through the exit opening and is present in the fluid flow in the wellbore. The method comprising the steps of providing a canister in said formation at a subterranean location within or proximate the wellbore said canister holding a traceable component and being provided with an exit opening and monitoring the fluid flow from the wellbore at a location remote from said canister for the presence of traceable component.
