Abstract: The present invention involves methods and apparatus for permanent downhole deployment of optical sensors. Specifically, optical sensors may be permanently deployed within a wellbore using a casing string. In one aspect, one or more optical sensors are disposed on, in, or within the casing string. The optical sensors may be attached to an outer surface of the casing string or to an inner surface of the casing string, as well as embedded within a wall of the casing string. The optical sensors are capable of measuring wellbore parameters during wellbore operations, including completion, production, and intervention operations.

Abstract: The present invention generally relates to an apparatus and a method for conveying and operating tools into a wellbore. In one aspect, a method of performing a downhole operation in a wellbore is provided. The method includes pushing a continuous rod into the wellbore, wherein the continuous rod includes a member disposed therein. The method further includes positioning the continuous rod proximate at a predetermined location in the wellbore and performing the downhole operation. In yet another aspect, a system for performing a downhole operation in a wellbore is provided.

Abstract: The present generally relates to apparatus and methods for instrumentation associated with a downhole deployment valve or a separate instrumentation sub. In one aspect, a DDV in a casing string is closed in order to isolate an upper section of a wellbore from a lower section. Thereafter, a pressure differential above and below the closed valve is measured by downhole instrumentation to facilitate the opening of the valve. In another aspect, the instrumentation in the DDV includes sensors placed above and below a flapper portion of the valve. The pressure differential is communicated to the surface of the well for use in determining what amount of pressurization is needed in the upper portion to safely and effectively open the valve. Additionally, instrumentation associated with the DDV can include pressure, temperature, and proximity sensors to facilitate the use of not only the DDV but also telemetry tools.

Abstract: A continuous rod string 100 is fed into in a deviated wellbore 10 from delivery reel 35. Delivery apparatus 30 provides the insertion force. The delivery apparatus 30 also includes a depth encoder 25 to record the amount of string 100 within the wellbore 10 at any given time thereby determining the position of a tool 110 within the wellbore 10. Data measured and recorded by the downhole tool 110 is then correlated with the depth encoder reading thereby defining the position of the tool 110 in the wellbore 10. This information is then used to form a "log" of measured data as a function of depth within the wellbore 10 at which the data is recorded. A communication line 105, which may be electrical or fibre optic, transmits signals from or to a downhole apparatus 110 such as a logging device or pump.

Abstract: The present invention generally provides apparatus and methods for reducing the pressure of a circulating fluid in a wellbore. In one aspect of the invention an ECD (equivalent circulation density) reduction tool provides a means for drilling extended reach deep (ERD) wells with heavyweight drilling fluids by minimizing the effect of friction head on bottomhole pressure so that circulating density of the fluid is close to its actual density. With an ECD reduction tool located in the upper section of the well, the friction head is substantially reduced, which substantially reduces chances of fracturing a formation.
