Well site Geologist, Sample collection and testing

As a Well Site Geologist, sample catching and testing procedures are crucial to ensure accurate and reliable data. Here's an overview of the steps involved: Sample Catching: 1. *Sampling Interval*: Identify the sampling interval based on geological markers, drilling parameters, or logging data. 2. *Sample Collection*: Collect samples from the drill pipe or core barrel at regular intervals or when a significant geological change is observed. 3. *Sample Description*: Record a detailed description of the sample, including lithology, texture, and any notable features. Sample Testing: 1. *Visual Examination*: Conduct a visual examination of the sample to identify any visible features or anomalies. 2. *Routine Core Analysis (RCA)*: Perform RCA tests, including: Grain density Porosity Permeability Saturation 3. *Special Core Analysis (SCAL)*: Conduct SCAL tests, including: Capillary pressure Relative permeability Electrical properties 4. *Geochemical Analysis*: Perform geochemical tests, including: X-ray fluorescence (XRF) Inductively coupled plasma mass spectrometry (ICP-MS) Fourier transform infrared spectroscopy (FTIR) 5. *Petrophysical Analysis*: Conduct petrophysical tests, including: Nuclear magnetic resonance (NMR) Computed tomography (CT) scans Procedures: 1. *Sample Handling*: Handle samples carefully to prevent contamination or damage. 2. *Labeling and Storage*: Label and store samples properly for future reference. 3. *Quality Control*: Implement quality control measures to ensure accurate and reliable data. 4. *Data Recording*: Record all data and results in a clear and concise manner. 5. *Communication*: Communicate results to relevant parties, including drilling engineers, geoscientists, and operators. By following these procedures, Well Site Geologists can ensure that sample catching and testing are conducted efficiently and effectively, providing valuable insights into the subsurface geology. #oil #oilandgas #waterreservoir #WellSiteGeologist #SampleTesting
