Conventional onshore de-risks wells or prospects before drilling, ranks well targets in terms of prospectivity, and helps delineate fields.
Looking ahead, this means that using our company’s patented process can save operators from spending wastefully on dry wells. Based on our current projects, we have made accurate predictions within a range of 70-98% accuracy.
We execute projects ourselves with a field crew in onshore conventional and, in collaboration with our customers, design the right survey which can be in a grid pattern over a large area, or cross-sections over a number of prospects and/or well targets. We then contour these to create a prospectivity map, or in cross-section, per prospect and will deliver a value of -1 to +1, whether prospect is dry or hydrocarbon charged. In the case of multiple prospects, we will provide a ranked or prioritised list.
We recently published the results of a conventional and unconventional onshore project in Argentina, where we successfully predicted well targets up to 97% accurately from our own fieldwork and data analysis.
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.
Unconventional onshore is where we enable operators to drill highly productive wells in shale versus the areas that will be uneconomic to exploit or drill.
In our recent unconventional pilot project we extensively sampled two shale fields in the USA, in the Bakken and the Eagle Ford areas.
In these projects, it was proven we help maximize returns on shale development by predicting productivity with 87% accuracy. This means there is no need to drill uneconomic wells, wasting resources and money and negatively impacting the environment.
Fieldwork is carried out by our own field crew, and typically we sample in a grid pattern every few hundred yards to one mile, depending on the resolution required as determined by the operator. After our full patented workflow, we deliver, after analysis and modelling, a contoured productivity map based on each and every prediction on each sampling location (-1 unproductive – +1 highly productive).

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)
Offshore is where we de-risk offshore wells before drilling and can rank prospects in terms of PoS.
We help de-risk drilling of expensive offshore wells by predicting hydrocarbon presence in the subsurface. We can rank different prospects based on Possibility of Success (PoS). These act as additional data points for our customers in order for them to decide what the wells’ profile and risk factors are. We can de-risk individual well prospects or provide a relative productivity ranking of a set of well targets. In essence, we help operators decide are these fields still charged and will this well be successful.
For offshore projects, we do this by teaming up with offshore surveyors. Alongside our customer, we decide on a sampling plan, which can be a large grid or more often a cross-section over the different prospects or well targets. We use simple drop-coring in order to acquire fresh seabed samples. At this moment we’re also exploring with our partner i-Drop smarter and more efficient ways of taking deep water samples.
Our technique is applicable in both shallow offshore and deep water and has been applied in most geological settings (including sub-salt).
The results of our most recent offshore project will be published soon.
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.
