What is the Membrane Interface Probe?

The Membrane Interface Probe (MIP) is rapid, high-resolution field screening technology that provides information about relative concentrations of VOCs in the subsurface, and the Electrical Conductivity of the soil.

The MIP uses a thin film fluorocarbon polymer membrane approx. 6.35mm in diameter which stays in direct contact with the soil during MIP logging. •The thin film membrane is impregnated into a stainless steel screen which serves as a rigid support for the fluorocarbon polymer. •The down-hole, permeable membrane serves as an interface to a detector at the surface. •Volatiles in the subsurface are getting transferred across the membrane and partition into a stream of carrier gas where they are swept to the detector. The membrane is heated in order to facilitate VOC transfer and self-cleaning.

Production rates: 150’ to 300’ per day.

The production rate of the MIP is affected by :

• the number of logging locations

• the depth of logging

• subsurface conditions

• access restrictions

• probe hole abandonment requirements

• weather

DIRECT SENSING

CPT/MIPCPT is (Cone Penetration Testing) commonly used to determine the subsurface stratigraphy in-situ and to estimate geotechnical parameters of the materials present in the subsurface.

•Collect real time physical descriptions •Collect physical properties of the soil matrix•Tag a confining layer•Cost savings over more traditional boring and sampling methods
