A cable protector clamp assembly that includes a clamp body configured to hold and align a cable along a pipe, the clamp body including a cable holder; and a stop collar configured to fix a position of the clamp body adjacent to a radially protruding element around the pipe and to prevent the clamp body from rotating around the pipe.

A tubular string formed by one or more tubulars with a central flow passage for an internal fluid therethrough and an external surface. The tubular having a wall thickness defined between external surface and the central flow passage and at least one sensor port disposed along a longitudinal length of the tubular. At least one sensor includes a main body and=nipple extending from the main body and inserted into the sensor port of the tubular. The nipple extends through the wall thickness sufficient to detect a property of an internal fluid within the central flow passage.

A control line clamp comprising a clamping element for retaining one or more control lines alongside a pipe; a first collar; and a second collar, wherein the clamping element is arranged to be attached to the pipe by positioning the first and second collars around the pipe on opposing sides of the clamping element and moving the first and second collars relatively towards each other in an axial direction.

A protective member at least partially surrounds a desired length of pipe (such as a conventional landing string) and protects “umbilical” control line(s) or bundles, including pipe and umbilical line(s) installed within risers of subsea installations. At least one robust protective shell member is installed around at least a portion of a pipe string and forms at least one elongated channel. At least one umbilical control line is disposed within the elongated channel and is shielded against damage from inadvertent or unwanted abrasion, impact or other forces.

The present invention provides an intelligent geophysical data acquisition system and acquisition method for shale oil and gas optical fiber. A pipe string is arranged in a metal casing, and an external armored optical cable is fixed outside the metal casing; an, internal armored optical cable is fixed outside the pipe string; the external armored optical cable comprises a downhole acoustic sensing optical cable, two multi-mode optical fibers, a strain optical cable and a pressure sensor array, and further comprises horizontal ground acoustic sensing optical cables arranged in the shallow part of the ground according to an orthogonal grid, and artificial seismic source excitation points arranged on the ground according to the orthogonal grid.

The present invention addresses to an improvement in a conventional packer, comprising the installation of an upper connector, a lower connector and an inner tube, adapted to allow the passage of hydraulic control lines and/or electrical cables internally to the packer mandrel, without interference with the passage of tools or flow. The conventional packer transformed according to the present invention aims at allowing controlling, from the surface, hydraulic equipment (sliding sleeve valves) or transmitting/receiving data from flow rate, pressure and temperature sensors (PDG—Permanent Downhole Gauge) that are positioned in the production string below the packer. The packer according to the present invention comprises an adapted upper connection (40), an adapted lower connection (50), and an inner tube (62), through which control lines or electrical cables internally pass.

A system includes an upper sheave configured to orient a cable towards a well, a lower sheave, having a center, configured to orient the cable towards the upper sheave, and a sheave stand. The sheave stand includes a shaft, running through the center of the lower sheave, configured to enable rotation of the lower sheave about a central axis, a sheave holder, fixed to the shaft, configured to hold the lower sheave in a vertical position, a tool leg, fixed to the shaft, configured to elevate the shaft to a height above a surface, and a floor stand, fixed to the tool leg, configured to anchor the sheave stand to the surface. The sheave stand stabilizes the cable by maintaining the lower sheave in a fixed rotational position.

A method of assembling an optical fiber cable on production casing includes positioning the optical fiber cable against a production casing at a hole of a well site, and affixing the optical fiber cable against the production casing by applying an adhesive to the production casing to secure the optical fiber cable against the production casing. The method further includes applying pressure to the adhesive to adhesively bond the optical fiber cable to the production casing along a length of the production casing while the production casing is being run-in-hole.

An improved cable guard and methods of use are provided for securing an MLE cable to an ESP system in a wellbore casing, the system having flange bolts and an annular channel. The cable guard may be unitary (i.e., one piece), comprising a body having a bridge portion and two side portions forming a cavity for securing the cable to the system, two connectors extending from the side portions, each connector forming at least one aperture for receiving a flange bolt, and skids extending from the side portions for guiding movement of the system within the casing. In some embodiments, methods of using the improved cable guard may comprise providing the cable guard, positioning the cable guard to receive the cable within the cavity and to receive at least one flange bolt within an aperture, and securing the cable guard to the system.

A control line clamp includes a clamping element for retaining one or more control lines alongside a pipe; a first collar; and a second collar. The clamping element is arranged to be attached to the pipe by positioning the first and second collars around the pipe on opposing sides of the clamping element and moving the first and second collars relatively towards each other in an axial direction.
