EDR, Electric drill Recorder, is an integral system that allows to obtain almost all the information generated during the activities of drilling and completion of wells, by means of analog and digital sensors. In addition to containing assistant programs of engineering assistance that executes mathematical algorithms making drilling optimization processes efortless. Being easy to use by drilling personnel through the use of a comprehensible human interface. There exist several levels of services, from the gathering, storage, visualization and remote transmission of the basic parameters of perforation to more advanced levels with detection and monitoring of flammable and toxic gases. Also, density, conductivity and temperature of drilling fluids. Our EDR system is capable of sending and receiving virtually any information through the WITS protocol.
