SAN DIEGO -- December 03, 2012

Osage Exploration and Development, Inc. (OTCBB:OEDV), an independent
exploration and production company focused on the Horizontal Mississippian and
Woodford plays in Oklahoma, updated the status of its accelerated drilling
program by announcing the spudding of two wells in the Company’s 31,000 acre
Nemaha Ridge project during the month of November. The two wells spudded in
November bring the number of wells drilled by the Company and its partners,
Slawson Exploration and U.S. Energy Development Corp., to seven. The McPhail
1-19H was spud on November 16th, and the Chambers 1-5H was spud on November

Additionally, Osage is pleased to announce the completion and commencement of
flowback on the Hopfer 1-17H, a Horizontal Mississippian well operated by
Devon Energy in which Osage owns a 14.6% working interest. The fracture
treatment of the Hopfer well was completed on November 25th, and the well is
currently flowing back fluids used in the hydraulic fracture of the wellbore.
The Devon Hopfer location is on the section immediately adjacent to Osage's
two McPhail wells.

Regarding planned completions, Osage intends to complete three wells by
hydraulic fracture treatment during the month of December: the Krittenbrink
1-1H, the McPhail 2-18H, and the McPhail 1-19H.

Management Comments

Addressing the current drilling program, Mr. Kim Bradford, Chairman and Chief
Executive Officer of Osage Exploration and Development, stated, “Our early
results have justified the acceleration in our drilling program which is
designed to hold progressively over 100 sections by production over the next
few years. The increase in our drilling rate will have a significant impact on
Osage’s production, revenue, and reserves. With several well results expected
in January, and more to come on a monthly basis thereafter, 2013 will be a
year of radical transformation for Osage.”
