Operations Update 

Amerisur Resources Plc, the oil and gas producer and explorer focused on South America, is pleased to provide an update on operations in Colombia. 

Platanillo N Sand Drilling 

The Company is pleased to report good progress on the civil works, a 3.8km new road and a location with three drilling cellars. This progress has been made in spite of adverse weather conditions and the discovery of unconsolidated zones on the route which required additional works to stabilise. The construction is expected to be completed in June, after which Rig D10 will be mobilised to drill Pintadillo-1, the first of up to three wells targeting the N Sand anomaly, which has been identified on 3D seismic. Pintadillo-1 will be a slightly deviated well, with a planned total measured depth of 8,448ft, and is expected to take less than a month to drill and log. 

The N Sand anomaly at Pintadillo is one of four such anomalies identified by the Company in the central part of the Platanillo block. It is estimated to hold P50 resources of 11.44 mmbo. 

Put-8 Drilling 

Amerisur has been informed by the Operator of block Put-8, Vetra Exploration and Production (50%), that the drilling contractor has been slightly delayed in the completion of their previous contract and the spudding of Miraparriba-1 is now planned to begin in June 2018. Miraparriba-1 will be drilled as a directional well to the Miraparriba structure within the Put-8 block. 

The Miraparriba structure is a low risk U and T sand light oil structural target covered by 3D seismic with gross P50 recoverable resources estimated at 4.4 mmbo by the Operator. 

Put-8 is a 102,799 acre block which lies adjacent to the west of the Platanillo field. 


The Operator (ONGC Videsh Ltd, 70%) has informed the Company that the preparations for the spudding of the well Indico-1 continue to advance despite adverse weather conditions in the area. The rig is now expected to mobilise in the latter part of June 2018. Mariposa-1 continues to produce in a stable manner and the operation to perforate additional zones in the well is expected to be performed within the next month. 

Indico-1 is targeting the same play as the successful Mariposa-1 well, but is further up dip in a larger structure. The Operator estimates a gross P50 recoverable resource at Indico-1 of 10.3 mmbo. 

CPO-5 is located to the south of the prolific Llanos 34 block and to the east of the Corcel fields. The block includes the producing Mariposa-1 well and the evaluation area related to the Loto-1 oil discovery. 

John Wardle, CEO of Amerisur said: 

"We are gearing up for a busy period of exploration drilling, targeting 26 mmbo of gross resource over the first three wells."
