Our technology, developed to analyze surface soil and seabed samples, recognizes otherwise undetectable hydrocarbon micro-seepage from highly prospective areas.
Different from traditional geochemistry techniques our solution filters cutting edge DNA analysis from over 340,000 microbial species with progressive Artificial Intelligence algorithms. This smart combination of the latest sophisticated techniques generates robust and accurate reservoir predictions.
Solution for efficient hydrocarbons exploration
In areas where Biodentify predicted no sweet spots prior to drilling well production rates proved to either below or indicated non-producing sites. Looking ahead this means that using our company’s patented process can save operators from spending wastefully on nonproducers.
Subsequent studies and modelling efforts have shown that the results of our research are reproducible. The prediction maps generated from DNA fingerprints of shallow soil samples form a very informative, additional information source (in addition to TOC, maturity, seismic, porosity and pressure maps) for exploration/production teams of operators.
Game changing technology optimizes development of unconventional plays. Biodentify approach is effective because the sensors used are incredibly sensitive, albeit indirect, as they collect data from the microbial ecosystem in the shallow soil.
Taking a closer look at the complex composition of microbes, we find not only those that flourish from microseepage, but also those that perish by it. It happens that the latter have lower concentrations above sweet spots. This discovery proves essential and wasn’t used in earlier microbial trials. More than 340,000 different species of microbes can be found in soil, of which a small number (from 50 to 200) react to these microseeps of gas.
Why we are so effective?
- Cost-effective process – only shallow soil samples needed across prospects, wells, or in a grid -no expensive (seismic) surveys
- Accurate predictions – in shale plays >70% accuracy
- Making use of the latest DNA sequencing and Machine Learning technology
- Using the existing database of > 2000 soil samples (known DNA + Production data)
Our technique is applicable in both shallow offshore and deepwater and has been applied in most geological settings (including sub-salt). Legacy samples can be used for analysis.
The technology has been successfully applied in conventional offshore for de-risking with an accuracy of more than 72%.
North Sea Case study
A North Sea operator was challenged when drilling several dry prospects after an earlier major discovery on a similar geological play. Our patented workflow was set to work to rank the remaining prospects. A survey was carried out, and over 200 sea bed samples (shallow soil) were taken, mostly along cross-sections over the prospects.
Prospects were ranked in order of productivity by adding up the results of the samples per prospect. Some prospects came out as clear ‘winners’ and were ranked high, for others the indicators were very clearly suggesting that no hydrocarbons are present.
Although the prospect drilling has yet to start, a discovered hydrocarbon accumulation as well as a dry prospect within the survey area were accurately predicted by the Biodentify workflow.
