Field Appraisal Studies
& Data Room Visits

Rapid technical review of petroleum opportunities, vendor data and subsurface uncertainty

Albian-Geo provides field-appraisal, data-room review and early-stage subsurface evaluation support for petroleum and natural-resource opportunities where vendor information, public-domain data, spatial datasets and geological interpretations must be rapidly tested before investment or drilling decisions are made.

Project experience includes worldwide geological appraisals, data-room visits, vendor-data review, play analysis, offset-well research, GIS and remote-sensing support, Petrel model construction, volumetric screening, infrastructure review, technical reporting and management presentations.

The focus is on converting incomplete or inconsistent opportunity data into practical technical judgement: what is credible, what is uncertain, what requires re-interpretation, and whether further investment, acquisition or drilling is justified

Key Capabilities

Subsurface and spatial data integration

Transformation of maps, seismic, wells, remote sensing, GIS, infrastructure and field data into working geological models, Petrel models and decision-support products

Play, prospect and basin screening

Assessment of source, reservoir, seal, trap, timing, migration, analogue basins, offset wells and geological chance of success

Data-room and field-appraisal review

Rapid technical evaluation of vendor material, legacy records, public-domain data, field observations and investment opportunity information

Project experience includes more than 13 geological field appraisals and data-room reviews worldwide, undertaken in close cooperation with downstream technical, commercial and management teams.

The general workflow involved transforming low-quality or incomplete vendor material into working geological, spatial and subsurface models that could support technical screening, opportunity ranking, investment decisions and recommendations for further work.

Public-domain data mining, offset-well research, play studies, remote sensing, GIS, infrastructure review and environmental / contamination-liability screening were used where relevant to strengthen the appraisal

Project done in cooperation with Dragonfiretech.ca

Geological appraisal of block in Middle Magdalena Valley, Colombia

Geological report and presentation to Client.

Reworking of vendor geo-spatial information augmented with public domain data:

Improved graphics and models
Enhance analysis and interpretations

Results:

Identified a 'screw fault" in vendor structural interpretation:
- ...this is not a strike slip fault, so not geologically possible in this context...

Play chance of success 80%
Prospect chance <5% (based on current information)

Recommendations:

To re-interpret the data before further investment or drilling prospect
Move drill location east:
- Safety from fault
- Confirm reservoir extent and volumes

Block 2, Sao Tome

Data room visit to location; report and presentation to Management.

Hydrocarbon play analysis and use of proxies:

Rio Muni Basin and Niger Delta

Data mining and general GIS support to project.

Conclusions:

Hydrocarbon accumulations should exist; all elements are present:

Source rocks, reservoirs (turbidite fan channel systems) and marine sediment seals
Time
Four-way closures leads identified in 2D seismic
Oceanic and onshore seeps

Risks:

Proximity to Cameroon Volcanic Line may impact oil quality
Unable to determine potential volumes at time of study
High costs: ultra deep drilling
Possibility of gas

Termit and Doba Basins, Chad

Transformation of vendor data into digital products and Petrel subsurface models for production profiles.

Hydrocarbon play and offset well research:

Volumetric calculations
GIS support to other Departments:
- Identification of existing 300 km pipeline route
- Use of lights at night to assess security-stability, local population and other related activity

Result:

Company proceeding with property acquisition.

Additional independent internal technical report on Doba Basin and a Farm-in opportunity.

Recommendation:

Company to invest in the Block-5 farm-in opportunity:

Developing basin
Access to export pipeline
Better internal security situation

Ukraine, Crimea & Siberia

Overview

Seven Blocks available in Dneiper-Donets Basin, East Ukraine
Two Blocks in Carpathian Basin, West Ukraine
Five Blocks in Siberia (Data room visit)
One block in Crimea

Original data in cyrillic and reserves classified using Russian system.

Creation of project database to manage all geo-spatial data.

Digitisation of vendor structure maps and wells; creation of individual Petrel models for use by reservoir engineers.

Result:

Five blocks in East Ukraine were selected for investment acquisition

Coal Bed Methane (CBM), Bulgaria

Company looking for new investment ventures.

Field visit to assess existing infrastructure.

CBM appraisal support included review of analogue projects and CBM development methods:

Use of analogue projects:
- White Dome
- Fairview
- Manville Coals
Educational lecture to staff:
- Providing a better general understanding of project and CBM methods/science

Construct of a 130 well Petrel model from vendor data to assess coal volumes.
