Global Experience
Lamu Oil and Gas Ltd., Kenya, block L1
Frontier Exploration
Our experienced and knowledgeable team reacts quickly and advises on
appropriate strategies for exploring a frontier block in a timely fashion
Project scope
> Play concepts to be targeted for exploration
> Review of regional geology and analogues
> Interpret legacy seismic data and tie with gravity, magnetics and wells
> Identify contractors for seismic operations
> Create ITT documents
> Bid evaluations, negotiations and contractor management
> 2D seismic design and parameterisation
> Overall supervision of field operations
> Processing supervision and QA / QC
> Seismic interpretation and geological modelling
> High grading of basin areas (basin modelling)
> Lead and prospect generation
> Exploration well proposal
Key features
> Complicated rift and inversion geology
> Poor quality legacy data (seismic and wells)
> Sparse data and lack of well control
> Poorly understood petroleum system
> Logistically challenging area to acquire new data
> Time pressure from government as per PSC terms

Subsurface
Global Experience
YFP, Nigeria, Aje field
Field Development
Our multidisciplinary team recommends technically sound development
options and delivers a field development plan on a tight schedule
Project scope
> Data gathering and review of existing geophysical interpretation – focus
on depth conversion
> Review existing and build new of static model
> Well test analysis / other Res Eng and dynamic simulation
> Aje-5 well location proposal and application to drill
> Conceptual FDP for Cenomanian Oil
> Project economics
Key features
> Complex depth conversion resulting in volumetric uncertainty
> Building viable models with limited well and history data which reflected
the range of dynamic uncertainty
> Fast iteration between subsurface and economic models for screening
of development concepts
> Assistance with regulatory approval
> Delivering development plan on tight schedule to operator

Seismic Interpretation and Prospect Identification
Our experienced and knowledgeable team provides seismic interpretation to
build a prospect inventory
Project scope
> Review of regional geology and analogues; tectonics, depositional
environments and petroleum systems
> Interpret newly acquired 3D seismic and merge with existing 2D project
> Lead identification and prospect inventory building
> Assist with farm out and data room
Key features
> Complex geology off the shelf
> Heavily faulted section with detailed structural interpretation
> Carbonate reef, structural and stratigraphic traps all identified
> Lack of well control of the shelf needed experienced regional
understanding of likely sedimentation and stratigraphy
