| Abstract |
In this paper we used the methodology applied for determining the damage effect from the production measurements. The maximum mass flow rate (Wmax) and the static pressure (pe) used in that methodology as variables into de global procedure, are used in this work as technical tool for reservoir characterization. Both parameters are used for calculation of the dimensionless values of WD and pD, which are graphed on the type-curve for determining the damage effect in a well. So, by this reason in this work we consider to those as intermediate variables in the application of the methodology above mentioned. In this work, production data of 17 of the wells incorporated to an exploitation continuous system were used. The methodology for determining the damage effect was applied and the results allow us to assume a correlation between production decline of the well and its exploitation time. In a same manner it can be observed that with exploitation time, values of Wmax and pe decrease for the same period of time. From the correlative analysis it was found that the methodology applied is useful in the characterization analysis of the interesting zones of the reservoir. Using the determined values of Wmax and pe with data of geographical location of the wells, it was possible to identify the distribution of such parameters along the reservoir area. Besides, using the values at initial conditions, it can get, among others, the distribution of the mass flow rate, static pressure, enthalpy etc., along the reservoir at its initial state. In this work we used, according to the methodology above mentioned, data of production measurements of wells incorporated to continuous exploitation system. The measured data in those wells were at three different discharge orifices. The obtained results allow us, to assume the presence of decline in the system, caused by continuous exploitation. Also were obtained the distribution of the calculated parameters along the reservoir. So, using this methodology it was possible to formulate technical criteria for the exploitation design of the wells. |
