Item 8.01.   Other Events and Regulation FD Disclosure

On December 14, 2005 Basic Earth Science Systems, Inc. (Basic, or the Company)
issued the press release attached as Exhibit 99.1 reporting on the Company's
operational activities in McKenzie County, North Dakota.

On its State #16-1H well, located in McKenzie County, North Dakota, Basic, along
with its partners, has completed drilling operations and is in the process of
moving the drilling rig off of the drill site in anticipation of attempting a
completion in the Bakken formation.

Configured as a single lateral horizontal Bakken well, the State 16-1H is
located in Section 16, T152N-R98W, The Bakken formation was initially
encountered at 11,066 feet. Despite encountering some difficulties while
drilling horizontally, both casing "through the curve" and a liner in the
horizontal lateral were successfully set. Drilled on a 320 acre spacing unit,
the well achieved 2,720 feet of horizontal exposure to the Bakken formation.
While "shows" of oil and gas were encountered during drilling, the "shows" were
not conclusive. Accordingly, while still very encouraged, the Company can not
speculate if commercial production will be established nor estimate initial
production rates.

The Company expects to finish completion operations in January 2006. Basic has a
20 percent working interest in the well and estimates spending approximately
$560,000 on drilling costs to date. The State 16-1H is operated by Missouri
Basin Well Service, Inc.

The Company previously disclosed that the State #16-1H well is part of a 13,500
acre block in which Basic has a twenty percent interest. The number of wells
that could be drilled on this acreage will depend on Industrial Commission
spacing requirements. However, with 640 acre spacing, this nearly contiguous
leasehold could contain locations for up to twenty wells; over forty wells if
320 acre spacing is granted. The State 16-1H is located on these lands.
