| dc.description | The complexity of conventional resources is increasing, and, therefore an optimum characterization is required. Existing models to study pressure behavior in heterogeneous formations consider only either constant-pressure or closed boundaries. In this paper the pressure derivative for a vertical oil well in a naturally fractured reservoir with a variable open external boundary is analyzed. The parameters governing the pressure response are: final flow rate at the external boundary (qWI) and time at which begins the invasion of fluid at the external boundary (τ), depending on its variability of these parameters, there are three conditions in which the external border acts: closed, partially open and constant-pressure. Lines and characteristic points were identified for each individual case to obtain the fundamental basis to generate the equations for the determination of the parameters that describe this type of reservoirs, such as: qWI and τ. Finally, the TDS technique was extended to interpret pressure tests in these systems. The methodology was satisfactorily verified by solving synthetic examples. | es_CO |
| dc.description.abstract | La complejidad de los recursos de rocas generadoras es cada vez mayor, por eso se precisa una óptima caracterización. Los modelos existentes para estudiar el comportamiento de la presión en formaciones heterogéneas consideran únicamente frontera abierta o frontera cerrada. En este trabajo se analizó la derivada de presión para un pozo vertical de petróleo en un yacimiento naturalmente fracturado con frontera externa abierta variable. La respuesta de presión está gobernada por dos parámetros: tasa final de flujo en la frontera externa (qWI) y tiempo en el que se inicia la invasión de fluido en la frontera externa (τ); dependiendo de la variabilidad de dichos parámetros, se presentan tres condiciones en las que actúa la frontera externa: cerrada, parcialmente abierta y abierta. Para cada caso estudiado se identificaron líneas y puntos característicos, base fundamental para generar las ecuaciones que determinan los parámetros que describen a este tipo de reservorios, como qWI) y τ. Por último, se extendió la técnica TDS para interpretar pruebas de presión en estos sistemas. La metodología se verificó satisfactoriamente con ejemplos sintéticos. | es_CO |
