In well test analysis, deconvolution is used to transform variable-rate pressure data into a single constant-rate 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 algorithm, it is applied to a synthetic example with known solution and an uncertainty analysis is performed to quantify the impact of non-uniqueness on multiwell deconvolution.

The use of the algorithm is further illustrated with a field example.
