Brownstone Energy Inc. (TSXV: BWN; OTCQX: BWSOF) (“Brownstone”) is pleased to announce a new oil discovery in the Une Formation at the Flami-1 well at the Llanos 27 Block in Colombia, and the following update from the operator.

As previously released, the Flami-1 well is the second well drilled by Brownstone and its partners at the Llanos 27 block, which commenced drilling on April 23, 2012. The well was drilled with the Saxon 132 1,500 horsepower rig and was successfully drilled to a total depth of 9,300 feet on May 31, 2012. Well logs indicated an estimated 20 feet of potential gross oil pay in the Mirador formation and 22 feet in the Une formation. Testing operations of the Une formation have now concluded and Brownstone and its partners are now preparing operations to conduct the test of the Mirador formation.

Une Formation Test

Testing operations commenced on June 13, 2012 with the Une formation being perforated at the 9,086-9,100 foot interval.

Phase 1 of the test involved producing out the drilling control fluids and cleaning the wellbore. Over a 60 hour period the well produced 1,515 BOPD of 15.5 degree API oil with an average watercut of 13%. Cumulative oil production over those 60 hours was 3,786 barrels of oil.

Following Phase 1 of the test the well was shut in to perform a 24 hour pressure build-up test. During this time, the formation pressure was measured at 3,850 psi.

Phase 2 of the test involved periodically stepping up the total fluid production rate to observe watercut and overall fluid production. Cumulative production over a 73 hour period was 5,496 barrels of oil and was produced in the following stages:

  • Stage 1: Over an initial period of 29 hours the well produced 1,403 BOPD (1,695 total over 29 hours) with an average watercut of 20%
  • Stage 2: The drawdown rate was increased and over a period of 20 hours the well produced 1,832 BOPD (1,527 total over 20 hours) with a watercut of 12%
  • Stage 3: The drawdown rate was increased and over a period of 15 hours the well produced 2,160 BOPD (1,350 total over 15 hours) with a watercut of 12%
  • Stage 4: The drawdown rate was increased and over a period of 9 hours the well produced 2,464 BOPD (924 total over 9 hours) with a 12% watercut.

These test results are preliminary and are not necessarily an indication of the longer-term potential of the well. Additional tests will be performed once the well can be placed on an extended test.

Mirador Formation Test

Operations are now being organized to conduct a test of the Mirador formation and results are expected in the next 2-3 weeks.

Following completion of the Mirador test, the well will be shut in while an application is made to the Ministry of Mines in Colombia to put the well on an extended test. This application approval is expected to take four to six weeks, at which time the well can be put back on production and oil from the extended test sold to market.

Brownstone is paying 50% of the total cost of the well and will earn 45.275% of production before payout and 34.25% of production after payout under a private participating interest agreement.
