Method And System For Completing A Well

Abstract

A technique facilitates the detection and measurement of formation properties with various measurement devices, such as logging tools. The technique comprises locating a standard tubular in a well such that the standard tubular extends to a zone of interest with respect to a logging procedure. A transparent tubing is attached to the standard tubing so as to extend along the zone of interest. Additionally, a protective material is directed to the region adjacent the transparent tubing to protect the transparent tubing from detrimental contact with deleterious well fluid.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]In many oil production operations, enhanced oil recovery techniques are employed to facilitate oil production. Many enhanced oil recovery projects use thermal recovery methods in which steam is injected to enable recovery of heavy oil. Production from heavy oil reserves is expanding worldwide.[0003]During enhanced oil recovery operations, formation properties are monitored at different locations within a reservoir. The monitored formation properties may include fluid saturation, interfacial fronts, wettability, pressure, temperature, and other properties as a function of time. Monitoring the various formation properties enables an operator to identify problems or the potential for problems that can interfere with oil production.[0004]2. Description of Related Art[0005]In some applications, monitoring wells are drilled at select strategic locations to enable use of logging tools and / or permanent sensors. If logging tools...

Benefits of technology

[0006]In general, the present invention provides a system and methodology for facilitating the detection and measurement of formation properties with various measurement devices, such as logging tools. The technique comprises locating a standard tubular, e.g. casing, in a well proximate a zone of interest to be logged. A tubing that is transparent to signals associated with logging tools, e.g. non-metallic and non-magnetic casing or liner, is attached to the standard tubing so as to extend along the zone of interest. Additionally, a protective material is directed to the region adjacent the transparent tubing to protect the transparent tubing from detrimental contact with deleterious well fluid.

Problems solved by technology

If logging tools are used to detect and measure formation properties, the logging techniques are carried out in an open hole completion because standard casings interfere with the logging measurements.

Attempts have been made to utilize casings that do not interfere with operation of the logging tools, however such attempts have met with limited success often due to the extremely harsh wellbore environment.
