Description

CROSS REFERENCE TO RELATED APPLICATION

[0001] The present application claims the benefit of U.S. Provisional Patent Application No. 61 / 896,009, filed Oct. 25, 2014; the present application is also a continuation in part of International Patent Application No. PCT / US2014 / 029992 filed Mar. 15, 2014, which in turn claims priority to U.S. patent application Ser. No. 13 / 843,746 filed Mar. 15, 2013, and to U.S. Provisional Patent Application No. 61 / 888,133 filed Oct. 8, 2013. The entire contents of each of the foregoing references is incorporated herein by reference.BACKGROUND OF THE INVENTION

[0002] Systems and methods directed to providing power to instruments in a downhole environment are generally described.

[0003] As people and companies continue to search for and extract oil, the quest for hydrocarbons has grown increasingly complex. For example, it is well known that the “easy oil” is generally gone, and exploration now requires searching to greater depths than ever before by drilling a ...
