Tarmat reservoirs subject to bottomwater drive are studied. Different shapes of tar layers are simulated physically and numerically to study the behavior of WOR and oil recovery. Four different cases were studied: a square barrier beneath the well, a disk beneath the well, a hollow square or disk beneath the well, and a half plane. The breakthrough time occurs earlier in the case of hollow tarmat barriers, while it is delayed considerably in the case of tarmat barriers shaped in the form of a disk beneath the well.
