Digital-Cuttings^TM (Pat. Pend.) creates a permanent high-resolution digital record of the drill-cutting rock sample, generating a rich, analytics-ready dataset that can be easily upscaled into regional and reservoir scale subsurface models, accurately calibrate rock physics models, or assist in predicting near-wellbore completion performance. It is suitable for all cuttings or core samples, no matter the vintage, well type, bit type or mud type.

Applications

Enhanced reservoir characterization
Input to static modelling
Regional sweet spot identification
Landing point assessment
AI-driven drill cutting particle segmentation
Digital downhole data generation
Digitization of rock repositories
High-resolution imaging at the wellsite
Automated lithofacies at the wellsite

Advantages

Case History

Example 1 | Example 2 | Example 3

Digitalization of a major Cuttings Repository: example North Slope, Alaska

100’s of wells & 1000’s of cuttings samples.
Different vintages of cuttings from the 1940s to the recent.
Analytical consistency.
Full digital record of every sample image, color extraction, elemental & liquid hydrocarbon quantification.

Umiat-11 well. Full, Digital-CuttingsTM Data Summary Chart of a 1,500ft 1940’s vintage vertical well, North Slope Alaska. The data display includes: Tops, SP curve, Cycle interpretation, Lithology, CGR, XRD, Resistivity, Color Extract, Brightness, Hydrocarbon Fluid & Source Rock facies data (G9+) and elemental anoxic, lithology, and marine indicators.

Using a Digital-CuttingsTM based approach to predict reservoir performance, Delaware Basin, New Mexico, USA

6 Lateral wells & >1,200 cuttings samples.
2 main reservoir benches.
Litho-BriteTM framework leading to ‘good rock vs bad rock’ interpretation & facies architecture predictions.
Strong correlation with quantitative mud-gas data.
Lateral wells with > proportion of ‘good rock’ out-performing wells with < proportion of ‘good rock’ facies.

2 Lateral wells from the Harkey Mills Sand bench of the Bone Spring Formation, Northern Delaware Basin, New Mexico, USA. The black line is the top Harkey Mills Sand pick for each Lateral well. Each plot includes MD (ft), tops, GR, Litho-BriteTM (green to brown colored zones), Brightness & anoxia elemental indicators. Green zones indicate channel-fill sands and relate to ‘good rock’, while brown colors indicate overbank deposits and relate to ‘bad rock’. When put on production Lateral 1 significantly outperformed Lateral 2, due to better completion stage performance in the higher proportion of ‘good rock’. Each Lateral is approx. 5,000ft in length from the top Harkey Mills Sand pick.

NOC requires better near-wellbore rock definition in key exploration well

400+ cuttings samples.
Litho-BriteTM interpretation provided a better reservoir definition.
Image analysis revealed a change in particle shape & size through the reservoir interval.
Good correlation with flow units.
