Equipment

The Pandey Lab utilizes the following dedicated equipment for experimental studies:

Pulse Decay Permeameter

Confining pressures up to 70 MPa in a half-hassler core holder. Pore pressure capability up to 20 MPa. Wide measurement range – from nano to millidarcy. Core size capability – 1” and 1.5”.

NanoK Permeameter

Measures the gas permeability of plug-size core samples. Effective confining stress capability up to 70 MPa using nitrogen or methane as flowing gas. Core size capability – 1” and 1.875” (NQ).

GCTS HTRX-070

Triaxial cell with 70 MPa pressure capacity and 1000 kN axial load capacity. Pore-pressure and core-flooding capabalites to measure various hydraulic properties using various flooding fluids. On sample strain measurement to enable flow-coupled-geomechanical testing, for example, stress path modeling with continued reservoir recharge/depletion. Sample sizes of 1” and 2” (NX) dia.

Shale Matrix Permeameter

Uses the Gas Research Institute protocol to determine shale and mudrock permeability of crushed material between 20 and 35 meshes using Helium pycnometry. Measurement ranges between 10^-15 md to 10^-3 md.

High Pressure Pycnometer

Custom made high-pressure pycnometer with pore-pressurecapability up to 12 MPa. Can be used to simply measure sample porosity. Additional modifications can allow for measurement of sorptive gas storage.

Osilla Contact Angle Goniometer

The Ossila Contact Angle Goniometer provides a fast, reliable, and easy method to measure contact angles of liquids on a variety of surfaces. Also, it enables measurement of surface tensions of liquid droplets.

Unconstrained Strain Setup

Custom made high-pressure pycnometer with pore-pressurecapability up to 12 MPa. Can be used to simply measure sample porosity. Additional modifications can allow for measurement of sorptive gas storage.

Pressurized Reactors

Multiple Parr and custom-made high-pressure reactors made of 316SS to enable rock exposure to pressurized fluids.

Micro-II Express Digital AE System

Physical acoustics Acoustic Emission testing system which holds upto 32 AE channels. Currently configured with an eight channel Express-8 AE board. Accompanied with a complete software package - AEWin. AEwin enables real time AE feature and waveform processing, display, fast storage and replay, along with 2D and 3D localization modules.

Agilent 990 MicroGC

Micromachined TCD detector with two columns – Molesieve5A and PoraPLOT-U providing gas measurement capabilities ofa wide variety of gases down to 500 ppb concentration. Typical run times of 2 minutes,providing high volume gas chromatography capabilities

Shimadzu QP2010 GCMS

Shimadzu Gas Chromatograph and Mass Spec with EI or NCI ionsource to enable mass-spec analysis for fluid samples with very low detection limits.

Gilson Sieve Shaker

8 or 12 in Tapping Sieve Shaker powered by a 1/3 hp heavy duty motor. Particle size range from 2 in to 635 mesh (50 m to 20 micron). Can use upto 10 full height sieves.

Benchtop Lab Mill  8000

Gilson LC-88 Benchtop Lab Mill for four sizes of milling jars from 0.5–10L (17–338oz). The mill can handle sample volumes from 75mL to 4L and can be handled with unattended ease.

Laboratory Coring and Subcoring Machine

This machine is specifically used in the laboratory for cutting core samples from hard materials such as rock and concrete. A clamp is provided to firmly secure the material during the cutting cycle. The coring area is protected by a transparent cylinder. A special clamping device to prepare rock samples from core pieces is also available.

Highland Park Rock Saw

Model 18 lapidary diamond saw is an 18-inch precision cutter, glass coldworking and lapidary equipment slab saw with heavy-gauge, powder-coated steel tank, powerfeed, crossfeed vise, and 1 horsepower 110v motor. Includes Highland Park's best precision diamond blade.
