Abstract

The paper determines critical rates to coning for horizontal and vertical wells shielded by favourably positioned impermeable horizontal barriers of limited lateral extent. Mathematical techniques mimic those used for unshielded coning. The Muskat approximation is employed. It turns out that vertical wells can benefit strongly from the presence of a barrier, as measured by the critical rate, depending on barrier position and radius. For horizontal wells, however, the presence of a barrier generally decreases the critical rate to coning.
