Upstream: Exploration and production of oil and gas via the Oriri field. Goland operates the Oriri Marginal Field (OML 88).
Oriri Field:
Goland is the Operator of the Oriri Marginal Field. Oriri Field is in OML 88, located offshore western Niger Delta, Bayelsa State, Nigeria. Average water depth is 42 ft.
The interpretation of the 1988 3D seismic survey of the Middleton/Ekeh area in OML 88 generated Oriri prospect. An exploratory well, Oriri-1 was drilled in a water depth of 42ft, as a straight hole to test prospective closures within the collapsed crest of the Northwest-Southeast trending Kulama ridge in OML 88. The well was spudded on December 31st 1991 and drilled to a total depth of 10,090 ft MD (9995ft TVDSS) on 28th February 1992.
Oriri field has several untapped stratigraphically stacked reservoirs located on the upthrown and downthrown of a generally collapsed crest roll over structure. Sand development in the area is persistent and correlatable across distances. The major reservoirs sand from younger to older series include the Uro sand, Iku, Ewinti, Ekiti, Ala, Odida and Manu sand. These sand bodies are prolific hydrocarbon bearing reservoirs in some of the adjoining fields and in the Niger Delta in general. Oriri-1 well made discovery in Ala-4 reservoir, proven to contain oil capable of flowing at an average rate of 1,500 barrels per day, beside gas reservoirs.
In 2006 Goland executed a JOA with Vitol Exploration Nigeria Ltd (VENL), allowing for 60% and 40% sharing of the Oriri Marginal Field asset respectively. ORIRI FIELD (OML 88)
OPL 917:
Goland holds 13% participatory interest in OPL 917 which is Operated by Afren Plc.
OPL 917 used to be a part of OPL 447, where large oil and gas accumulations have been discovered. Although two exploratory wells have been drilled to date, there still exist several untested accumulations in the OPL. OPL 917 is located onshore within the Cretaceous – Early Paleocene Anambra Basin, which lies immediately to the north of the highly petroliferous Niger Delta. Geologically, OPL 917 straddles Anambra Basin and the transitional zone bordering the Niger Delta. The main stratigraphic units of prospective hydrocarbon source and charge are the Santonian Nkporo and Maestrichtian Mamu Formations, and possibly the Agbada Formation. The Igbariam-1 drilled in 1971 discovered 194 ft of net gas and 30ft of possible light oil or condensate.
