Abstract
Coiled tubing (120) is used to drill into a subsurface formation and provide a conduit back to the surface to allow sensors (200) to be deployed and measurements made for monitoring of the formation. A method of monitoring subsurface formation properties between injection and production wells comprises using coiled tubing (120) to drill sensor holes at predetermined positions between the injection and production wells and fixing the coiled tubing permanently in the hole such that a sensor (200) can be deployed in the tubing to provide measurements of the formation.
