Papers and Publications

Estimation and modelling of reservoirs properties through seismic attributes and geostatistics in gas fields, southern Spain. SOVG, XIV Venezuelan Geophysics Congress

I was co-author of a paper published in the XIV Venezuelan Geophysics Congress, in 2008. In this paper is performed a study of Seismic reservoir characterization (it's when you use seismic data for the estimation of rock properties). We used geostatistics to integrate seismic data and well logs.

Also, because in this area we found clear amplitude anomalies, we analyze the origin of the anomalies in one of the reservoirs in this area.

There are many methods trying to find a relationship between seismic attributes and well logs. The most basic method would be to plot a seismic attribute against a rock property and make a linear regression to find a relationship between the seismic attribute and the rock property.

The geostatistical methods are much more complex than linear regression but they are more reliable.

The attributes we used were: the instantaneous amplitude, amplitude RMS, instantaneous frequency and phase.

Estimación y modelado de propiedades de yacimiento a través atributos sísmicos y geoestadística en campos de gas del sur de España. SOVG, XIV Congreso venezolano de Geofísica.

También, debido a que en esta zona la data sísmica muestra claras anomalías de amplitud, se analiza el origen de la anomalía de amplitud generada por uno de los yacimientos tipo en el área de estudio.

Métodos como la regresión lineal proveen información acerca de la relación de los atributos y los datos de pozo.

Los métodos geoestadísticos son mucho más complejos que los métodos de regresión lineal, pero producen resultados más confiable.

Atributos utilizados: amplitud RMS, amplitud instantánea; atributos de frecuencia, frecuencia instantánea y fase; así como superficies de impedancia acústica.

Con datos provenientes de estos 5 pozos se realizaron entonces los gráficos cruzados correspondientes para tratar de obtener alguna relación lineal, y los mejores resultados obtenidos se muestran en la Tabla 1

Posteriormente, se realizó un análisis de una de las anomalías de amplitud observadas. Con dicho propósito generamos un gráfico de la magnitud de la reflexión Rpp vs. θ (ángulo de incidencia) para un yacimiento gasífero que genera fuertes anomalías de amplitud negativa

Esto se hizo a través de las ecuaciones de Zoeppritz tomando los datos de ρ y Vp de los registros de pozo, y utilizando el modelo de Castagna et al. (1985) para estimar Vs

Por otra parte, causa suspicacia el hecho de que el yacimiento considerado presenta un espesor bastante pequeño (7 m). Esto nos obliga a pensar en la posibilidad de que las amplitudes anómalas observadas respondan a un efecto de entonación.


Estudio del efecto de entonación

Para modelar este efecto se diseñó una cuña que simula el comportamiento de una capa que se afina progresivamente. Los valores de densidad y velocidad asignados a este modelo fueron los correspondientes al yacimiento de interés

La ondícula empleada para simular la respuesta sísmica de esta cuña fue una Ricker fase cero con una frecuencia dominante de 60 Hz.; valor obtenido a partir del espectro de amplitudes de un grupo de trazas que muestran la anomalía producida por el reservorio considerado. A través de estos parámetros se obtuvo la respuesta sísmica que se muestra en la Figura 7 (a).

El modelo mostrado en la Figura 7 (a) exhibe el efecto de máxima entonación a un espesor de aproximadamente 7 m; esto implica que nuestro yacimiento no es lo suficientemente espeso como para poder diferenciar la reflexión del tope y la base del mismo, produciéndose una superposición de ambas reflexiones. Este modelo comprueba la hipótesis de un incremento de las amplitudes sin relación alguna con la presencia del gas.
