Multiple Well Deconvolution

Abstract: In well test analysis, deconvolution is used to transform variable-rate pressure data into a single constantrate drawdown suitable for interpretation. It is becoming part of a standard work flow for exploration and appraisal well test analyses and in production test analysis where there are no interference effects from nearby wells. This paper develops and extends the single-well deconvolution algorithm of von Schroeter (2004) to the larger and more complex multiwell deconvolution problem. To validate the algo… Show more

“…Thus combining sandface flow rate with pressure measurements will enhance the conventional (including type curve) well test interpretation methods. On the other hand, mathematically, deconvolution is also a highly unstable inverse problem because small errors in the data can result in large uncertainties in the deconvolution solution [10,11].…”

“…Within the lumped parameter model, the continuous-time transfer function noise (TFN) modeling is widely used to simulate the hydrological system output in response to external forcing (von Asmuth et al, 2002). This approach employs a response function along with the convolution technique to represent various external forcing factors, such as recharge events or pumping activities (Ahmadi et al, 2017;Chakrabarty & Enachescu, 1997;Cumming et al, 2013;Gringarten, 2008;Hwang & Lu, 2007;Kuchuk et al, 1990;Levitan, 2003;Osman et al, 2017;Roumboutsos & Stewart, 1988). The groundwater level data might be noisy due to a combination of different external forcings.…”
