Abstract
A multiple branch well for use with in situ leach mining of deep lying ore bodies. The branch wells may be formed by a method disclosed in a related invention. Each well may have two branches one of which is a producer well and one an injector well. Internally of the main casing from which the two branch casings extend are--from the lower end up--a packer unit, a tubing hanger, and a wireline retrievable hydraulically generated pump. The packer and tubing hanger serve their conventional function of, respectively, blocking the flow of leach fluids and holding the branch tubular casing in place within the main casing. The hydraulic pump joins the tubular casings to maintain a constant ratio of produced fluid to injected fluid. This pump is operated by a pressurized fluid source. Since it is retrievable and hydraulically operated, the pump can be brought to the surface for any repairs or maintenance and it requires less surface plumbing with no down hole electrical power.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
