Basic Earth Reports On North Dakota Re-entry

Denver, Colorado, December 18, 2006 — Basic Earth Science Systems, Inc. (Basic) (OTC:BB BSIC) reported that production on the State #16-1H, a horizontal re-entry in McKenzie County, North Dakota, has substantially improved following equipment modifications performed earlier in the month. Last week, the oil/water ratio had increased to greater then 20% and oil production had increased to 120 barrels of oil per day. However, recent diagnostics indicate that the well is still capable of greater productivity and further modifications will be undertaken in the near future. Previously a vertical Mission Canyon producer, the well was re-entered in October of this year and three horizontal legs were added to enhance production. Prior to the reentry the well was making 35 barrels of oil per day. Basic has a 20% working interest in the State #16-1H that is operated by Missouri Basin Well Service.

“With this production and the likelihood of further gains, we are more than encouraged by these results,” commented Ray Singleton, President of Basic. “Indeed, as we continue to make progress in productivity, the likelihood of further drilling efforts in this area become more of a reality. However, at this point, it would be premature to predict if we will reach our goal of 250 barrels of oil per day or what our stabilized production rate will be.”
