Well testing is the cheapest and most accurate tool available to find the distance from a well to a linear constant-pressure boundary or fault. Several methods exist in the literature with which to determine this parameter. Most of them use conventional analysis and are only useful for isotropic reservoir systems. The few methods for anisotropic systems obtain the well-to-discontinuity distance through conventional analysis, type-curve matching and TDS technique, and then a correction by anisotropic effects is applied. In this work, a unified behavior of the pressure derivative was found, so the new shorter and most practical expressions used to find the distance from the well to the discontinuity, including the simultaneous effects of anisotropy angle and anisotropy index, are included. These new formulae were successfully tested with two synthetic examples and one field case example, and deviation errors higher than 30% are observed if an anisotropic system is treated as an isotropic one.
Las pruebas de presión constituyen la herramienta más económica y precisa disponible para encontrar la distancia desde un pozo a un límite ofalla de presión constante lineal. Existen varios métodos en la literatura para determinar este parámetro. La mayoría de ellos usa análisisconvencionales y solo son útiles para sistemas de yacimientos isotrópicos. Los pocos métodos para sistemas anisotrópicos obtienen ladistancia entre el pozo y la discontinuidad a través del análisis convencional, el ajuste de curvas de tipos y la técnica TDS, y luego se aplicauna corrección por efectos anisotrópicos. En este trabajo, se encontró un comportamiento unificado de la derivada a presión, por lo que seincluyen las nuevas expresiones más cortas y prácticas para encontrar la distancia desde el pozo a la discontinuidad, incluidos los efectossimultáneos del ángulo de anisotropía y el índice de anisotropía. Estas nuevas fórmulas se probaron con éxito con dos ejemplos sintéticosy un ejemplo de caso de campo, y se observan errores de desviación superiores al 30% si un sistema anisotrópico se trata como si fuese unsistema isotrópico.
