and these usually, as a rule of thumb, produce something like a factor of 3x the uplift compared to a vertical well if successful. This gives a rough range of 1,000-5,000 bopd from these three wells.
However, with drilling the concept of a "sure thing" does not exist. Therein lies a big part of the risk and the opportunity that markets price into companies like this. Amerisur do operate in a relatively low risk area, as compared to oil basins in other regions both onshore and offshore. According to management, the average success rate since 1966 of a well bringing oil to surface is 85% in the area. Another caveat though, �bringing oil to surface� is not the same thing as flowing commercial barrels.
If all three wells came in it�s likely management would continue to drill further wells here using up the spare slots on location which would be the best result for shareholders.
Licence CPO-5 (Amerisur owns 30% with ONGC as operator) is also a three well campaign targeting the Indico, Aguila and Sol prospects. Management gives a net 40.58 mmbo (million barrels of oil) estimate for all three wells combined, and it flags this estimate as conservative.
Two interesting facts about these wells are:
Firstly, the nearby Maripasa-1 well was previously a success, testing at 5,400 bopd but choked back to 3,000 bopd of current production from only 10ft of perforation, out of 110ft of pay depth. Since initial production in November 2017 there has been no drop in pressure or flow at all and it could be that this producing asset has much better sizing than initially appreciated. The 10ft of perforation is likely to be increased by another 22ft which should, therefore, increase the wells production rate.
Secondly, in the block to the north (LLA-34) are a series of producing fields (combined production 55,000 bopd) owned by Geopark and Parex. Through a series of successful drilling campaigns these fields have significantly increased in resource and production in the last three years.
Amerisur�s three drilling prospects are all on trend but focused on different structure types which have been somewhat derisked by their similarity to the successful Mariposa-1 well. Any success from each of these wells could make a significant difference to valuation. It�s worth noting that Geopark has taken its Colombian production from 3,440 bopd in 2012 to almost 22,000 in 2017, mainly on the back of its assets to the north of CPO-5.
Putumayo 8 (50% ownership) sits to the west of the currently producing Platanillo block and the all important OBA export pipeline. Here AMER is due to drill two wells, the first one is actually being drilled from their neighbours existing and producing oil pad but into Amerisur�s block meaning any success can be brought onto production rapidly whilst the second well has a choice of two objectives and a final decision will be dictated by results from the Platanillo drilling (mention
