According to reports in June 2019, Repsol and partners has suspended the Boyuy X2 new-field wildcat (NFW) well on the Caipipendi block with non-commercial gas from the Huamapampa Kipe (deep) formation in early-May 2019 after the well previously produced 0.5 MMscfg/d in March 2019 during testing. Along with water production and some gas, the well reportedly also showed low permeability in the sand for the hydrocarbon to flow to surface. Boyuy X2 reached its total depth (TD) of 7,963 m (26,125 ft) in February 2019 after the operator encountered gas below 7,640 m, compared to where the Huamapampa reservoirs would normally be found between the depth of 4,000 and 5,800 m. Notably Repsol and partners decided to continue operations on the well after previously reaching its originally assumed TD of 7,220 m (23,688 ft) in early-August 2018, which made Boyuy 2 it one of the deepest wells in the region. Planned total depth of the well was 6,500 m (21,325 ft), with objectives of three reservoirs in the Huamapampa Formation. Repsol operates the block with 37.5% stake, joined by partners Shell with 37.5%, and Pan American Energy (PAE) with 25% interest. Investment for the project was said to be USD 130 million. Local reports indicated that the companies plan to drill the Boicobo Sur X1 exploratory well next, although there is still possibility of testing Boyuy X2 further in the future to see if commercial gas can be recovered.  Caipipendi block covers approximately 1,314 sq km of onshore land in the Chaco Sub-Andean Zone of Chaco Basin. The Margarita-Huacaya gas mega-field is located nearby, where the companies have confirmed the discovery of two new reservoirs, Huamampampa 3 (H3) and H1C, in the Huamapampa Formation back in 2015.  Plans for exploration activities in the Boyuy area were originally outlined back in October 2016 when Repsol and its partners signed the addendum and extension agreement for Caipipendi with state company YPFB. The addendum specifically involves the implementation of a USD 500 million program to explore the Boyuy and Boicobo prospect areas (estimated potential of 3 Tcf of gas) over through 2021. Reports from the Bolivian Ministry of Hydrocarbons and Energy (MHE) indicated that the extension adds another 10 years to the contractâs original expiration date of 2031, but can still be extended further up to 15 years if results from the new prospects are positive with the total investment cost expected at USD one billion through 2046.  Background Information    The Boyuy and Boicobo exploration prospects in Caipipendi, along with another one called Ipaguazu, were first identified in February 2016 through data analyses from 2D and 3D seismic surveys carried out by Repsol between 2013 and 2015. It was estimated then that they could possibly add approximately 636 MMcfg/d of total production to Bolivia starting in 2019.
