An Integrated Structural Interpretation and Modelling Workflow for the Barikewa Field, Papua New Guinea


Compression since the Late Miocene has resulted in highly folded and faulted stratigraphy within the Papuan Basin making the search for and development of hydrocarbon resources difficult. A structural interpretation based on a variety of data sources is required to confidently quantify the potential range of resources associated with a field. Due to highly variable topography, including limestone karsts and dense forest coverage, seismic acquisition and processing is challenging and expensive in the PNG Highlands. The result is often a poor seismic image and hence other data sources are utilised in an integrated workflow to interpret the sub-surface. In this paper, the authors describe a structural interpretation workflow used to accurately model the Barikewa Gas Field in a 3D geo-cellular model. The workflow involves the integration of surface geology, surface and well dip measurements, palynology, strontium isotope data and fault analyses along with 2D seismic interpretation. The result is a structurally robust container from which a geo-cellular model can be constructed.
