Estudio de factibilidad técnica para la reinyección de cortes de perforación en el bloque 43 ITT, Campo Tambococha.

Abstract

The present study about reinjection of drilling cuts in Tambococha location, was focused in the selection of proper areas to be intervened, such areas must meet various parameters, they must be capable of guarantee the storage, contain the debris product of drilling campaigns without affecting the environment and fresh water bodies nearby also oil reservoirs that can be of interest. The study was written based on lithological, petrophysical, geophysical and mechanical tubing data, given by Petroamazonas Block 43 Operations department. It was determined that Sandstone T has the capacity to store waste from 32 wells, thus being more efficient than conventional disposal. In addition, it was observed that the CRI process is a closed-circuit method, which generates zero discharges on the surface, avoiding environmental liabilities. Fracture simulation was performed by sensitizing pumping rates (3, 4, 5 and 6 bpm) and the percentage of solids contained in the slurry (10%, 15% and 20%). So it was determined that the optimal percentage of content in the injection of solids is around 15%. Likewise, it was evidenced that at pumping rates of 4 and 5 bpm, more controlled fracture dimensions are obtained, compared to the results of 6 bpm. Additionally, the economic technical analysis was carried out based on the CRI process, which reinjects waste from several wells into a single formation, reducing operational costs compared to conventional disposal.
