Abstract: A cable for use in a wellbore can include an outer housing and a chamber disposed coaxially within the outer housing. The chamber can have a cross-sectional end length that is substantially the same as an inner diameter of the outer housing. The cable can also include a fiber optic cable disposed in a nonlinear arrangement within the chamber. The cable can also include a conductor disposed adjacent to the chamber within the outer housing. The conductor can be usable for transmitting power to a well tool.

Abstract: A system for launching or retrieving wireline electro acoustic technology (EAT) sensor assemblies in a downhole wellbore comprises an EAT launcher/retriever section and an EAT sensor assembly for placement in the EAT launcher/retriever section. The EAT launcher/retriever section comprises an external high pressure housing, attachment means at each end of the external high pressure housing, and a wedge shaped internal retractable launcher plate with an opening on one side to allow a fiber based wireline cable to pass through the EAT launcher section. The EAT sensor assembly comprises a center section comprising sensors and two end sections, each end section with a set of extendable grippers to grip a fiber based wireline cable, wherein the center section and both end sections comprise a V groove that allows the EAT sensor assembly to be centered on the fiber based wireline cable.

Abstract: Example systems and methods are described for performing multilateral well sensing in a downhole environment. In an example system, a cased parent wellbore and a cased lateral wellbore intersect at a lateral junction. A sensor is deployed within the cased lateral wellbore that communicably couples to a transmitter module, wherein the transmitter module is deployed within the cased lateral wellbore downhole of the lateral junction and configured to generate acoustic signals. An optical fiber cable is deployed within the cased parent wellbore and configured to receive acoustic signals transmitted by the transmitter module in the cased lateral wellbore.

Abstract: Systems and methods for distributed acoustic sensing based on coherent Rayleigh scattering are disclosed herein. A system comprises a pulse generator, an interferometer, a photo detector assembly, and an information handling system. The interferometer comprises a first and second optical switch each comprising a plurality of ports. The information handling system activates one port on each of the first and second optical switches so as to vary the optical path length of the interferometer. A method comprises splitting backscattered light from an optical pulse into a first portion and a second portion, activating one port of a first optical switch and one port of a second optical switch, sending the first portion into a first arm of an interferometer, sending the second portion into a second arm of the interferometer, combining the first and second portions to form an interferometric signal, and receiving the interferometric signal at a photodetector assembly.

Abstract: A method is described for compensating measurement errors of fiber Bragg grating (FBG) sensors installed in fiber cables in downhole oil and gas environments due to hydrogen darkening. The method involves loading a fiber of known length and multiple FBG sensors in a hydrogen chamber with control of temperature, hydrogen concentration, pressure, and time and adjusting each of the variables through a test matrix while continuously measuring and recording the fiber transmission loss and FBG spectrum changes, then creating a correlation map of fiber transmission loss vs. Bragg wavelength shift, and using that map for compensating the wavelength shift of downhole installed fiber cables as a function of their hydrogen induced transmission loss through time.

Abstract: A system and method to minimize the likelihood of cable damage due to downhole operations such as perforating is disclosed. The system includes at least one transducer and at least one orientation device positioned adjacent a cable. A wireless signal from the transducer and/or orientation device is transmitted towards the cable. The wireless signal influences a wired signal transmitted in the cable. The influenced wired signal is used to identify the axial and radial orientation of the cable. The transducer may be secured to a mid-joint collar on the casing string in a portion of the wellbore to be perforated. The transducers are identified and located by the control system and a perforating tool can be adjusted to point away from the cable before firing of the perforating tool.
