Our innovative cuttings sample workflow aims to extract data with maximum value from cuttings in the most cost-effective way.
The cuttings workflow involves our newest cuttings technologies such as Spectral Gramma Ray (SpetralGR), Nuclear Magnetic Resonance (NMR), and Fourier Transform Infrared Spectroscopy (FTIR).
Our technology of Spectral Gamma Ray using as-received wet cuttings or dry-washed cuttings provides high-quality data of K, U, Th, and SpectralGR.
Non-destructive, fast (~3 mins per sample), and cost-effective
1) Determine confidence level between results from drill cuttings and downhole logs
2) Resolve ambiguity on cuttings depth shifts
3) Provide alternative gamma log when downhole GR log is uncertain or absent
4) Estimate shale or clay contents, clay typing, organic matter, and depositional environment
5) QC mudlogging and store wet cuttings and so forth
Our cuttings Technology of Nuclear Magnetic Resonance (NMR) using as-received wet cuttings provides quality data of NMR T2 distribution, Clay Bound Water (CBW), "Bound" Fluids, "Free" Fluids, Total Fluids, T2logmeanCBW, and so forth.

HAWK Pyrolysis classical method identifies type and maturity of source rock organic matter and hydrocarbon potential. The HAWK instrument, through a programmed heating process, provides critical information needed to estimate hydrocarbon potential.
Measurements from the pyrolysis classical method are:
S1: free oil content
S2: remaining generation potential
Tmax: temperature at maximum evolution of S2
S3: organic carbon dioxide yield
HAWK PAM method provides evaluation on mobile hydrocarbons.
Measurements from the HAWK PAM method are listed below.
