Alvopetro Energy Ltd. announces initial results from the first interval tested in our 183-B1 well on our 100% owned and operated Block 183 and October 2022 sales volumes.
In July 2022, we completed drilling the 183-B1 exploration well to a total measured depth ("MD") of 2,917 metres. Based on open-hole wireline logs and fluid samples confirming hydrocarbons, the well discovered hydrocarbons in multiple formations with a total of 34.3 metres of potential net hydrocarbon pay, with an average porosity of 10.6% and average water saturation of 29.0% using a 6% porosity cut-off, 50% Vshale cut-off and 50% water saturation cut-off.
Alvopetro has completed the 183-B1 formation test in the Sergi formation, the deepest of three formations with hydrocarbons shows during drilling of the well. We perforated a total of 26.5 metres in the Sergi formation at various intervals between 2,811 metres MD and 2,886 metres MD. We initially swabbed 63 bbls of oil and 7 bbls of completions fluid during the initially clean-up period. After a short shut-in we then initiated the production test. Cumulatively, over the duration of the 72-hour production test, we recovered 59 bbls of 43°API oil, 7 bbls of water identified as completion fluid, and 0.28 MMcf of associated gas. The daily oil rate recovered during swabbing operations averaged 20 bopd.
The 183-B1 well has now been shut-in to measure reservoir pressure and obtain pressure build up data to undertake a pressure transient analysis, which will help predict productivity of this first zone. After completing the pressure build-up test, the first interval will be suspended temporarily with a bridge plug and the test will proceed up-hole to test the Agua Grande formation.
October Sales Volumes
October sales volumes averaged 2,720 boepd, including natural gas sales of 15.6 MMcfpd and associated natural gas liquids sales from condensate of 124 bopd, based on field estimates, an increase of 3% over our average daily sales volumes in the third quarter. October sales volumes include initial sales volumes from our 183(1) well on our Murucututu project where we commenced production in mid-October following completion of the commissioning of field production facility. Our team continues to optimize the field production facility at the wellsite. Since coming on production, the well has averaged approximately 0.42 MMcfpd based on field estimates.
