1. L'INFORMATION BREVET AU SERVICE DE L'INDUSTRIE PÉTROLIÈRE : CAS DE CONCEPTION ET D'OPTIMISATION DES TRÉPANS PAR INGÉNIERIE INVERSEE
The aim of this paper is to show the results of a study originally conducted for an Algerian State-Owned Company ENSP (Manufacturing Branch / formerly ALDIM) specialized in drill bits manufacturing. We show innovation opportunities offered by the use of reverse engineering assisted by patent information in the oil industry. This applied research, mainly base

2. Assessment of simulated mandibular condyle bone lesions by cone beam computed tomography
There are many limitations to image acquisition, using conventional radiography, of the temporomandibular joint (TMJ) region. The Computed Tomography (CT) scan is a better option, due to its higher accuracy, for purposes of diagnosis, surgical planning and treatment of bone injuries. The aim of the present study was to analyze two protocols of cone beam comp

3. Improvement of the productivity in getting holes in aviation aluminum alloys with high speed tools / Melhoria da produtividade na obtenção de furos em liga de aluminio aeronautico com ferramentas de aço rapido
The purpose of this study is to optimize the manufacturing process of holes made by Company X in one of their products. Besides the optimization, should be maintained the dimensional quality by controlling the diameter, roundness, circularity, and surface finish of cylindrical holes obtained by the widening process, with high-speed steel reamers in a aluminu

5. EVALUATION OF DRILL BIT PERFORMANCE TAKING INTO ACCOUNT THE IN SITU STRESSES / EVALUACIÓN DEL DESEMPEÑO DE BROCAS DE PERFORACIÓN CONSIDERANDO EL ESTADO DE TENSIONES IN SITU / AVALIAÇÃO DO DESEMPENHO DE BROCAS DE PERFURAÇÃO LEVANDO EM CONTA O ESTADO DE TENSÕES IN SITU
The present dissertation describes a correlation between the bit performance and the state of stress acting upon the rock formation located immediately beneath the bottom of the wellbore. Bit performance data from 6 wells drilled offshore Brazil were collected and anlyzed. In order to reduce the empiricism associated with this type of data analysis, a study
