    Abstract: A method for obtaining location information about a well as it is being drilled through a subsurface, comprises: providing at least one fiber optic cable deployed in a borehole within acoustic range of the well, the proximal end of the cable being coupled to a light source and a photodetector, the fiber optic cable being acoustically coupled to the subsurface formation so as to allow acoustic signals in the subsurface to affect the physical status of the cable, providing an acoustic source in the well, transmitting at least one light pulse into the cable, receiving at the photodetector a first light signal indicative of the physical status of at least one first section of the cable. The first section is selected so that the first light signal provides information about the position of the acoustic source, and outputting at least the information to a display.

    Abstract: Method of fracturing an earth formation by pumping a pressurized fracturing fluid into a borehole in an earth formation thereby fracturing the earth formation. At least during the pumping, a strain distribution is monitored in an object that is located in the earth formation and that is mechanically interacting with the earth formation. The borehole system has a plurality of strain sensors for monitoring the strain distribution in the object during fracturing. After terminating the pumping of the pressurized fracturing fluid, mineral hydrocarbon fluids may be allowed to flow from the reservoir into the wellbore or another wellbore, and produced via that wellbore.

    Abstract: A system and a method that are useful for making temperature measurements that are distributed over a distance. In one aspect, the system comprises a plurality of Bragg grating measurement points disposed in an optical fiber with a predetermined spacing between adjacent Bragg grating measurement points. The system also comprises a substrate with the optical fiber disposed thereon, the optical fiber wrapped around the substrate with at least one predetermined wrap angle. The predetermined wrap angle and the predetermined spacing may be selected to allow a temperature measurement signal to be distinguished from a bending measurement signal. The substrate may have a first coefficient of thermal expansion greater than a second coefficient of thermal expansion of the optical fiber and may comprise alternating sections of hollow tube and solid rod.
