Description: Camesa EM cables are designed specifically for oil and gas well logging and mechanical operations. They provide 1) a strength member to covey tools and instruments through the well 2) an electrical pathway to power the instruments or tools 3) an electrical pathway to communicate between the down-hole and surface instrumentation 4) a means to measure depths within the well.
Mono-Conductor Cable Applications These single conductor armored cable are primarily used to perform oil and gas well completion operations, and to monitor well production. The operations include mechanical service, such as perforation, cutting casing and tubing, and setting plugs and packers. Operations also include well logging, such as cement evaluation, casing and tubing inspection, production logging, and some types of formation and reservoir evaluation.
Multi-Conductor Cable Applications The multi-conductor cable is used primarily by wire-line service companies on newly drilled, uncased wells. A stronger cable with more conductors, than what is used for completion and production logging service, is required for the open-hole jobs. The cables must be capable of carry a heavier string of instruments, Additionally, more conductors are needed to handle the increased complexity of the data transmission requirements, as well as to handle the increased power requirements.
Coax-Cable Application
The Coax-cable was developed to reduce signal attenuation of the transmitted data experienced with the use of the conventional conductors. Coax-cables are used for wire-line services, which require the transmission of extremely high volumes of data over a short period of time. The primary application of the Coax-cable is for imaging, e.g. video image of the bore-hole wall or casing. Coax-cables can also be used to improve the signal to noise ratio for services with lower data transmission rates.
Fiber Optic Cable Applications
Fiber optic cables are used for similar applications as coax-cables. Due to the superior data transmission rate of the fiber optic cable, video images can be transmitted real time and at a much higher resolution than what can be achieved via the use of coax-cables.
Jacketed EM Cable Application
The jacketed cable is used primarily for storage well monitoring services, where the cable is exposed to corrosive bore-hole fluids over an extended period of time. The jacket is designed to designed to protect the armor wires from the corrosive fluids, and prevent the cable armor wires from corroding
