The system and method provides a drill collar made of a non-conductive or substantially non-conductive composite material positioned within the borehole. A downhole component is capable of collecting at least one measurement and is embedded within the composite material of the drill collar. The at least one measurement collectable by the downhole component is related to the borehole or the formation about the borehole. ## Claims ### Claim 1 A system for collecting at least one measurement within a borehole formed in a formation, the system comprising: a drill collar made of a non-conductive or substantially non-conductive composite material positioned within the borehole; a downhole component capable of collecting a measurement and embedded within the composite material of the drill collar, wherein the measurement collectable by the downhole component relates to the borehole or the formation about the borehole. ### Claim 2 (depends on 1) The system according to claim 1, wherein the composite material is fiber reinforced polymer composite material. ### Claim 3 (depends on 1) The system according to claim 1, wherein the downhole component is embedded within a wall of the drill collar and is configured to collect the measurement through the wall of the drill collar. ### Claim 4 (depends on 1) The system according to claim 1, wherein the downhole component comprises at least one first coil, an antenna, a sensor or an electrically isolated electrode. ### Claim 5 (depends on 4) The system according to claim 4 further comprising: a retrievable mandrel having a second coil positioned within an interior of the drill collar, wherein the retrievable mandrel and the downhole component embedded within the drill collar are adapted to transmit or receive a wireless communication via the at least one first coil of the downhole component and the second coil of the retrievable mandrel. ### Claim 6 (depends on 5) The system according to claim 5, wherein the wireless communication comprises wireless telemetry data, wireless electronic instructions or wireless electrical power. ### Claim 7 (depends on 5) The system according to claim 5, wherein the wireless communication between the retrievable mandrel and downhole component embedded within the drill collar comprises radio frequency signals. ### Claim 8 (depends on 1) The system according to claim 1, wherein the measurement collectable by the downhole component is an electrical potential measurement, an electromagnetic wave measurement, a gamma radiation measurement, an acoustic measurement, a nuclear measurement, a resistivity measurement or a conductivity measurement. ### Claim 9 A method for collecting at least one measurement within a borehole formed in a formation, the method comprising: deploying a downhole component within the borehole, wherein the downhole component is capable of collecting a measurement relating to the borehole or the formation about the borehole; protecting the downhole component with a shielding element made of non-conductive or substantially non-conductive fiber reinforced polymer composite material. ### Claim 10 (depends on 9) The method according to claim 9, wherein the downhole component is a logging-while-drilling tool, measuring-while-drilling tools, near-bit tool, or a wireline configurable tools. ### Claim 11 (depends on 9) The method according to claim 9, wherein the downhole component is embedded within the composite material of the shielding element. ### Claim 12 (depends on 9) The method according to claim 9, further comprising: collecting the measurement through the shielding element with the downhole component. ### Claim 13 (depends on 9) The method according to claim 9, wherein the shielding element is formed as a drill collar, a sleeve or a pair of interlocking half shells. ### Claim 14 (depends on 9) The method according to claim 9, further comprising: embedding metallic materials within the composite material of the shielding element, wherein the metallic materials are metallic strips or tilted coils. ### Claim 15 A method for collecting at least one measurement within a borehole formed in a formation, the method comprising: positioning a drill string having a bottom hole assembly within the borehole; and electrically insulating a first position on bottom hole assembly from a second position on the bottom hole assembly with a drill collar made of non-conductive or substantially non-conductive composite material. ### Claim 16 (depends on 15) The method according to claim 15, wherein the composite material is fiber reinforced polymer composite material. ### Claim 17 (depends on 15) The method according to claim 15 further comprising: embedding at least one acoustic attenuator, flow line for hydraulic fluids, or energy harvesting device within the composite material of the drill collar. ### Claim 18 (depends on 15) The method according to claim 15 further comprising: embedding a coil, an antenna, a sensor, a hollow metallic cube, an acoustic impedance ring, an energy harvesting piezoelectric strip, or an energy harvesting electromagnetic device within the composite material of the drill collar. ### Claim 19 (depends on 15) The method according to claim 15, further composing: positioning a transmitter at the first point on the bottom hole assembly;
