In the Oil & Gas industry, before production can take place in a well, it must first be completed. In simple terms, completion is the intermediate process between drilling and extraction. When it comes to intelligent completion, it refers to a system capable of collecting, transmitting and analyzing data originated from the production, the reservoir and the completion itself. In other words, it covers all instrumentation operations necessary so that the natural resources contained within the reservoir can be extracted in a safe and controlled way. To operate these devices from the surface, control lines are used, and they can be hydraulic and/or electric. One of the many challenges associated with these lines is the junction of independent cable sections, where these couplings are achieved with splices. Because of its critical importance and due to the extremely hostile downhole environment, rigorous testing proves necessary to make sure there are no shortcomings during its operation. This study proposes the execution of these tests, as well as the equivalent simulations, and the comparison between both. The specimen in question are two splice models, a hydraulic one and an electric one. The objective is to simulate through software and to test in laboratory an exemplary of each model, under different static solicitations. Afterwards, to analyze the results in order to verify the veracity of the tests and to assure the integrity of these components once in real life work conditions.
