    Abstract

    Permanent Down-hole Gauge (PDG) has been widely installed in the oilfield around the world in recent years. One of the challenges in analysing long-term, real-time, dynamic data such as transient pressure from PDG is the diagnostic and analysis of data with interference from other wells during the production. This type of data is very common in practice, while the published technique such as deconvultion algorithm failed in handling this problem. Based on traditional interference test theory, muti-well deconvolution algorithm has been developed to address the problem in handling transient pressure with interference. A computer programme has been coded, a number of synthetic cases were studied, which proved that the developed algorithm works well for the problem stated above. This paper presents the study results of applying the developed multi-well deconvolution technique in the diagnostic, processing and analysis of the numerically simulated transient pressure with interference. It was demonstrated that the interference effect can be identified, the published deconvolution algorithm failed in handling such data set, while the developed multi-well deconvolution algorithm worked well. The paper shows that only after this data processing procedure, further analysis of the transient pressure data using methods such as decline curve analysis etc. is possible.
