Fundamental measurements on reservoir rock core, Routine Core Analysis, provides geologists and engineers with their first “hard data” related to the downhole environment. PTS Labs recognizes this value and strives to deliver the highest quality routine measurements.
Core Plugging & Slabbing
Core sample physical properties are usually determined from 1.5" diameter plug samples cut from bulk subsurface core. For whole-core analysis, the cylindrical core material is cut length-wise (into two "slabs") using a specially designed saw. The slabbed cores can be displayed for description, viewing, or documentation.
Basic Properties
Basic properties are measured on cleaned, dry samples drilled from the whole core by diamond-bit core drills. Our lab is equipped with the latest CORETEST Systems AP-608 automated permeameter/porosimeter (see ANNOUNCEMENTS). Standard basic property measurements are helium porosity and permeability (Klinkenberg corrected).
X-Ray Computed Tomography (CT) Analysis
X-ray computed tomography is now the industry-wide technology for whole-core inspection, core-log correlation, and plug sample characterization. PTS has recently completed a major renovation of the CT laboratory with the installation of a new scanner (see Announcements). Capabilities include 0.35-mm resolution, radiographic (pilot/scout) scanning, up to 140 kVp at 200 mA, and scan times up to 4 seconds. With these capabilities and our SUN-based workstation, we can provide clients with state-of-the-art CT core inspection and characterization. Standard output includes CT radiograph plus axial CT scans. Plug scans may also include both longitudinal and axial CT scans.
Sidewall Core Analysis
PTS capabilities include rapid handling and processing of both rotary and percussion sidewall cores. Services provided include bulk volume, porosity, fluid content, laser grain size analysis (LPSA), air permeability (empirical estimate), and photography (color and UV). The PTS staff is well experienced in deriving the most representative characterizations from these types of cores.
Photographic Services
PTS Labs is fully equipped with customized equipment for displaying and photographing cores. Extreme care is taken to color match the actual core with the prints. Using a new procedure developed at PTS, ultraviolet light photographs are color corrected to allow a clear distinction between oil-saturated zones and clay laminations.
Digital Imaging
Converting your existing core photos to digital images allows electronic storage and manipulation of data. PTS Labs can convert and provide images in many formats including web site ready files, CDs, and cross-platform formats (PC, Mac and UNIX). We also offer secure, long-term storage for photographic records, engineering data and reports.
