According to local reports in August 2018, Zeus Ol has reached the total depth of 3,900 m (12,795 ft) on the Don Juan 2 stratigraphic well on its 100%-held Boqueron block (formerly known as Cerro Leon) in late-June 2018. The well was spudded in March 2018 with the original planned TD of 4,200 m (13,780 ft).  The Boqueron block covers approximately 23,500 sq km of onshore land in the Izozog High and Chaco Sub-basin area of Chaco Basin.  Prior to Don Juan 2, Zeus has previously plugged and abandoned the Don Juan 1 earlier in March 2018 at the depth of 2,780 m (9,121 ft) due to technical reasons. The well was spudded in January 2018, after it was originally planned for May 2017, as the program was met with multiple delays due to weather conditions and contract restraints. Planned total depth (PTD) of the well was said to be 3,500 m (11,483 ft), with the purpose of investigating Upper Silurian sandstones as a conventional target and possibly lower Devonian shales for unconventional.  Don Juan 2 is the third stratigraphic well in the Boqueron block following Mariscal Estigarribia 1 in 1969, and also only the second well drilled in the block, after Don Juan 1, since Parapiti 1 new-field wildcat (NFW) was plugged and abandoned in July 1977 with oil and gas shows in the same objectives.  Background Information  According to reports from January 2017, Zeus Ol officially received the Concession Law Contract rights for the Boqueron block by resolution of law No 5761/16 dated 2 December 2016. Prior to the new rights, Zeus Ol has performed a 2D seismic survey covering 1,350 km in 2015 during the Prospection Permit stage.
