Abstract: In one aspect the invention provides a ball injecting apparatus for releasing balls into the wellbore of a well. The apparatus comprises a body having an interior capable of housing one or more balls, at least one window in the body to allow for fluid communication between the body's interior and outside atmosphere. The window also provides for placement and removal of the balls into and out of the body's interior. An opening of suitable dimensions is provided on the body to allow the balls to exit the apparatus. A ball retaining and release mechanism retains and selectively releases the balls out the opening. The interior of the ball injecting apparatus is open to atmospheric pressure during operations. System and method aspects are also provided.

Abstract: A fluid containment system comprises a plurality of curved panels having a front face a rear face, a top end, a bottom end and two side ends, wherein the plurality of curved panels are positioned serially adjacent one another in a generally upright or vertical manner so as to comprise a generally circular arrangement, with each of the plurality of curved panels further comprising at least one fastening member on its front face and wherein the fastening member is suitable to generally abut to a similar fastening member of an adjacent curved panel. Once fastened, the plurality of curved panels may be lined with a liner and used for fluid storage. In another aspect a fluid handling and containment apparatus comprises a tank suitable to hold a volume of fluid, the tank having a main compartment with a plurality of outlets exiting from the main compartment.
