Gran Tierra is a TSX
and NYSE listed E&P with a focus on Colombia. Its main assets are the
Costayaco and Moqueta fields in the Putumayo Basin which accounted for 88% of
the company’s Colombian NAR production of 18.4mboe/d in 2014. The company also
has an exploration portfolio in Brazil (supported by minimal production of
900bbl/d NAR in 2014) and Peru. In March 2015, Gran Tierra announced that it
was suspending development operations on the Bretana field in Peru following
disappointing drilling results at the end of 2015; all reserves related to the
development have now been re-categorised as contingent resources. Exploration
activities are expected to continue in the Peru with outstanding commitments of
USD160mm over the next three years.
Although the company’s
flagship assets are performing strongly, there are two unwelcome pieces of
information buried in the company’s 10-K filing – there is an overriding
royalty on the Putumayo blocks and a legal claim filed by the ANH against Gran
Tierra over royalties.
Gran Tierra entered
Colombia in 2006 through the acquisition of Argosy Energy’s assets in the country
(Santana, Guayuyaco, Chaza and Azar blocks). Gran Tierra increased its
interests in certain assets through the subsequent acquisition of Solana
Resources, most importantly, taking the interest in the Chaza block from 50% to
100% in 2008. The original interests in 2006 are subject to a third party overriding
royalty under an agreement entered into between Gran Tierra and Crosby Capital
in June 2006. The agreement also allows for Crosby Capital to convert its
royalty into a net profit interest (“NPI”) in certain circumstances. As at the
end of 2014, the following arrangements were in place with Crosby Capital:
·
10% NPI on
the originally acquired 50% WI in the Costayaco and Moqueta fields which lie in
the Chaza block
·
35% NPI on
the 35% WI in the Juanambu field in the Guayuyaco block
·
Various
overriding royalty on production in the Santana block and Guayuyaco field in
the Guayuyaco block
The ANH has also filed
a claim against Gran Tierra in relation to the HPR royalty. This is a royalty which
is paid on top of normal royalties and is triggered when the oil sale price
exceeds c.USD37/bbl and cumulative production from an exploitation area exceeds
5mmbbl. The HPR royalty affects Gran Tierra’s Costayaco and Moqueta fields which
are separate exploitation areas, but lie within the same block (Chaza).
Given the two fields, Costayaco
and Moqueta, are separate exploitation areas (with the company further emphasising
that they are separate hydrocarbon accumulations), Gran Tierra is currently
only paying the HPR royalty on the Moqueta field which has recovered in excess
of 5mmbbl to date. As at the end of 2014, recovery on Costayaco had reached
4.2mmbbl and therefore Gran Tierra has not yet commenced the payment of HPR
royalty on this field.
The ANH have taken a
different interpretation of the Chaza contract and view that the 5mmbbl
threshold should be applied to aggregate cumulative production across all
exploitation contracts within the Chaza block, meaning that Costayaco would
also be subject to the HPR royalty. The ANH has challenged Gran Tierra’s
position with a claim of USD64mm in respect of Costayaco HPR royalties. Gran
Tierra and its legal advisers do not view that the ANH claim will be successful
and the company has not made a provision in its accounts for this potential liability.
