Abstract
A system for conducting operations in a well penetrating laterally into a subsurface producing formation. A first string extends from the surface down the well through a downhole pump and then a special tee-like fitting to the lower end of the well. A second string extends from the surface to the side connection in the special fitting. A downhole pump is located in the first string above the fitting.
