In mid-July 2018, GeoPark announced that it had tested oil in the Tigu-1 exploration well on the LLA-34 Block located in the Llanos Basin. The well was drilled south east of the main fault line of the Jacana oil field. The NFW tested 1,100 b/d of 17 degrees API oil with a 1% water cut from the the Guadalupe Formation using an ESP in early July 2018. The well drilled in Q2 2018 reached a final TD of 3,565m. The company is going to amass production data and potentially carry out more drilling to delineate the potential of this discovery.Nearby the Tigui Sur-1 NFW was spudded on 29 April 2018 on the LLA-34 Block, and reached a TD of around 4,047m on 25 May 2018, according to information released by the ANH. GeoPark plans to test the well in Q3 2018. Partner, Parex Resources previously reported that the well was to assess the northern extent of the Totoro-1 discovery made on the Cabrestero Block. The prospect is near the southern boundary of the block located in the Llanos Basin. The well is also likely to have been targeting the Guadalupe Formation.GeoPark is still working on a full appraisal and delineation of the Tigana-Jacana Field complex in LLA-34, but current certified 2P reserves of 164 MMboe as of December 2017 have been certified independently by DeGolyer and MacNaughton Corp. Tigana was discovered in December 2013 and Jacana in August 2015 with production from this complex representing 80% of total production from the block. GeoPark Colombia (GeoPark 80% & LG International 20%) operates the block with 45% WI and Parex holds the remaining 55% WI.
Tigui 1 (Winchester 45% op, Parex 55%), SE of Jacana field in LLA-34 block, target N. extent of the Totoro discovery in the adjacent Cabrestero block (Guadalupe Mirador Fms) and tested 1 100 b/d of 17Â°API oil on ESP. TD=3565m.
