Gran Tierra's Grand Tour (into Ecuador)

Gran Tierra has won three blocks in Ecuador covering c.140,000 acres in the highly prospective Oriente-Putumayo Basin: Charapa, Chanangue and Iguana. The blocks are contiguous with Gran Tierra’s Putumayo position in Colombia and allows the company to extend its Colombian success on the trend across the border.

Gran Tierra will have 100% interest and operatorship on each block in exchange for a 14 well, four year work programme – management plans to commence the programme in 2020, to be fully funded from internal cash flow.  The contracts work on a sliding scale for contractor share of revenues, ranging from 87.5% at USD30/bbl to 40% at USD120/bbl.

The Charpara block sets Gran Tierra off to a good start with an existing field and historical production from the B-Limestone. As Gran Tierra matures its new acreage, there is scope to construct its own gathering infrastructure and use the export infrastructure in Ecuador. In due course, this could also be an export route for its Colombian production in the same way that Amerisur has built its own OBA pipeline from its Platanillo block to Ecuador (see Bienvenido Victor Hugo and Putumayo smart crude marketing).

The other side of the border into Ecuador has always been an exciting play. Whilst geologically the same trend, the Colombian side of the border has been underexplored due to historical above ground conflict and security issues. In contrast, Ecuador has been highly successful with many fields where nearly 6bnbbl of oil has already been produced.

Putumayo smart crude marketing

Putumayo producers are blessed with having multiple export routes and the flexibility that affords in maximising sales netbacks.

The most direct route is the OTA pipeline to Tumaco. However this route has historically been plagued by attacks leading to downtime and the South Blend crude at Tumaco also fetches one of the biggest discounts to benchmarks vs. other region blends.

This has led to producers accessing Ecuadorian export routes through either the OCP or SOTE pipeline to Esmeraldes. At the port of Esmeraldes, the two key blends are Napo (19° API) and Oriente (24° API). Oriente being the lighter crude fetches a higher price.

Another option that has been employed is the trucking or part truck/part pipe of crude to Coveñas. At this port, the Vasconia blend fetches a good price and sells into the Caribbean market.

At the end of 2016, Amerisur completed its OBA pipeline linking its Platanillo field directly to Ecuadorian export infrastructure. Previously, Amerisur had to truck crude to a pipeline entry point to the OSO or OTA pipeline. The OBA link allowed Amerisur to reduce average transportation costs from c.USD14/bbl to below USD4/bbl. The link, despite taking many years to complete, cost USD18 million and in February 2018 Amerisur announced that the pipeline had been paid by within 15 months with cost savings achieved to that date of USD20 million.
