Abstract
A contingency for non-operation of a valve in a side pocket mandrel of production tubing includes creating a selective barrier to fluid communication across sidewalls of the production tubing. The barrier is formed by an insert that is installed in the side pocket mandrel, which includes a valve that responds to pressures inside and outside the production tubing to selectively allow fluid flow across the production tubing sidewalls. Types of the valve include a surface controlled gas lift valve, an inflow control valve, and an inflow control device.
