Optimización de la producción mediante cañoneo con bajo balance para pozos de alto ángulo

Abstract

Well perforating is one of the most fundamental processes when well production is in its initial stages; the correct execution of this procedure is essential to generate benefits to the production overall. In Ecuador, most of jobs in high deviated wells are done with underbalance perforating techniques which can affect directly to the reservoir due to the increase of the crushed zone resulting in a negative impact on the productivity. Nowadays trough incorporation of a pressure transference system added to the perforating string is possible to transmit pressure below the packer once it is set and generate the underbalance conditions needed for the operation. This technique was applied in block 16 in Ecuadorian east, the purpose of this paper is to obtain a result analysis of the underbalance perforating technique.
