RE:Quinde-3 New Successful Development Well & Quinde Oil Pooland here is more info from the same locked SA article about the Suroriente Block where the Quinde oil field and the Cohembi oil field are:
1) Suroriente Block: The Suroriente Block covers approximately 90,000 acres and produces light and medium gravity oil from three oilfields (the Pinuna-Quillacinga field, the Cohembi field and the recently discovered Quinde field).
In fact, this Block was Suroco's gold mine. Producing wells in the Pinuna-Quillacinga field have multiple oil-bearing reservoir zones, with the production derived from the Villeta U and T sands, with an average oil gravity of 29 degrees API. The Cohembi field produces from the Villeta 'N' sand with average oil gravity of 19 degrees API. And in terms of the Quinde field, several gushers were drilled there over the last months.
The water injection in the Cohembi oilfield commenced in December of 2012 in the Cohembi-1 well, and the expansion of the secondary recovery injection scheme continued in 2013. The expansion continues in 2014, and the comprehensive reservoir studies indicate a waterflood at Cohembi will result in a significant increase in recovery and booked long-life reserves.
Potential to further increase those values by polymer injection is the subject of a third party consulting study that is currently ongoing and will be completed in 2014.
