Calderdale Geoscience Limited (CGL1) is a London UK-based, petroleum exploration consultancy. Formed in April 2004, CGL comprises a company of independent geoscientists and engineers who specialise in the following disciplines:
As petroleum provinces mature, the amount of spatially organised data proliferates making the process of synthesising information and discovering new resources ever more difficult and time-consuming. CGL has strived to become expert at mining technical and commercial information from such data, using existing mapping and GIS tools, and has focussed on developing spatial databases from these data, which can help accelerate the exploration process. This regional, ‘data driven’ approach facilitates the ready production of digital, thematic maps at all scales and of any theme, such as: maps of depositional systems and structural style at the basin scale; the reservoir, seal and charge components of common risk segment maps at the play scale; and prospect risk maps at the licence and block scales.
Dave Melnyk brings years of geological and GIS experience to this exploration discipline.
Supported Technologies: Manifold GIS™ QGIS™ MapInfo™ Surfer™ MapViewer™
CGL believes that it is important for any sensible seismic interpretation to be based on a very good understanding of the stratigraphy, tectonics and depositional systems at a regional scale. This understanding provides insight and constraints as to what types of structures, faulting and stratigraphic geometries might be expected. To this end CGL maintains an extensive library of surfaces, wells and other data, which can be utilised in the early stages of interpretation to provide stratigraphic context and verify the seismic signature of the target horizons. In addition, CGL has a long tradition in stratigraphic and geological analysis; and strives to remain innovative in these disciplines.
Jo Prigmore and Dave Melnyk have worked together for several companies as interpreters and explorationists. Chris Johns has produced many Competent Persons' Reports (CPRs). Paul Emerson specialises in reservoir characterisation and has worked on many equity redeterminations. ERCE brings quantitative interpretation and rock physics expertise.
Supported Technologies: IHS Kingdom™ OpendTect™ PetroMod™ Strater™ Crystal Ball™ MathCad™
With over three decades of experience in data-loading, and developing and populating relational databases for the geosciences, CGL can now offer the following: geological and geophysical database design and build; data capture and formatting; data-room build and support; data-sales.
Pete Stanley has solved many data loading and data reformatting problems by providing clients with bespoke programming and database solutions.
Supported Technologies: SQL support and Relational Data Storage Design; .NET Application Development; Customised Scripting.
Members of CGL have worked on many Licence Rounds over the years, many of which have resulted in successful applications.
Mike Dempsey, Chris Johns, Dave Melnyk and Jo Prigmore bring many years of licence round work experience, gained within major oil companies.
CGL was an early player in unconventional resource calculation and has worked the Devonian shale gas play of the eastern USA.
Tissa Jayasekera and ERCE bring over 30 years of reservoir engineering, petrophysics and unconventional resource experience.
1 CGL is privately owned by the directors and by Equipoise Solutions Ltd.
