摘要:
A device and method for delivering fracture fluid (e.g., erosive materials) into an oilfield wellbore while the well has wireline, coiled tubing, jointed tubing or any other apparatus encumbering the flow path of the erosive fluid that is being injected into the device. The device provides the ability to insert and remove equipment in the wellbore during fluid treatment while maintaining access to the full wellbore diameter. The invention also provides a method for delivery and positive, down-hole displacement of material (i.e., diverting material including, but not limited to buoyant ball sealers).
