However, these solutions have a technological configuration that are out-of-date, mainly because analog radios and inefficient communication topologies are used. On the other hand, solutions based in digital radios can provide more efficient solutions related to energy consumption, security and fault tolerance. Thus, this paper evaluated if the Wireless Sensor Network, communication technology based on digital radios, are adequate to monitoring Oil and Gas onshore wells. Percent of packets transmitted with successful, energy consumption, communication delay and routing techniques applied to a mesh topology will be used as metrics to validate the proposal in the different routing techniques through network simulation tool NS-2 / Grande parte do monitoramento de po?os petrol?feros terrestres realizados atualmente est? baseado em solu??es sem fio (wireless). Todavia, essas solu??es apresentam uma configura??o defasada tecnologicamente na medida em que s?o utilizados r?dios anal?gicos e topologias de comunica??o ineficientes. Por outro lado, tecnologias que adotam r?dios digitais podem proporcionar solu??es mais eficientes relacionadas com o consumo de energia, seguran?a e toler?ncia a falhas. O trabalho investiga se as Redes de Sensores Sem Fio, tecnologia de comunica??o que utiliza r?dios digitais, s?o adequadas para o monitoramento de po?os petrol?feros terrestres. Porcentagem de pacotes entregues com sucesso, consumo de energia, atrasos de comunica??o e t?cnicas de roteamento para uma topologia em malha s?o as m?tricas usadas para validar a proposta atrav?s da ferramenta de simula??o NS-2
