Gregg Drilling is very pleased to announce that after their clients requests, two highly in-demand new services have been added!
Starting on July 6th, 2015 Gregg Drilling will able to provide the following services:
- Sonic Drilling
The Mid-Roto Sonic 50K (MRS) features a full size sonic head on a compact crawler with typical depth capabilities of 6” casing to 300’ through nearly any geology. The MRS also features true 100% rod handling making it one of the safest Sonic drill in the Unites States. This is the primary reason Gregg Drilling selected this specific rig to enter into the field of sonic drilling. Sonic drilling is renowned for its high quality samples, drilling speed, and capacity compared to rig weight, size and costs. This state of the art equipment can be used to overcome typically problematic areas, provide higher quality samples and typically drill at a higher production rate than conventional methods with less waste.

- Membrane Interface Probe (MIP) & Hydraulic Profiling Tool (HPT)
Gregg Drilling has added also a new tool to its suite of in-situ probes. The new MiHPT detects volatile organic contaminants (MIP), measures soil electrical conductivity (EC) with a standard dipole array as well as incorporating the Hydraulic Profiling Tool (HPT) to measure injection pressure using the same down-hole transducer as the stand-alone HPT system. Using simple post-processing, you can estimate hydraulic conductivity (K) and water table elevation. Download Guide.
MIP: How it works
The Membrane Interface Probe (MIP) is a screening tool with semi-quantitative capabilities acting as an interface between volatile contaminates at depth in the soil and gas phase detectors at the surface. The MIP membrane is semi-permeable and is comprised of a thin film polymer impregnated into a stainless steel screen for support. The membrane is approximately 6.35mm in diameter and can be easily replaced. The membrane is placed in a heated block attached to the probe. This block is heated to approximately 100-120 degrees C as the probe is advanced into the soil. Heating the block accelerates membrane diffusion while at the same time minimizing membrane absorption.
HPT: How it works
The Hydraulic Profiling Tool is a logging tool that measures the pressure required to inject a flow of water into the soil as the probe is advanced into the subsurface. This injection pressure log is an excellent indicator of formation permeability. In addition to measurement of injection pressure, the HPT can also be used to measure hydrostatic pressure under the zero flow condition. This allows the development of a hydrostatic pressure graph for the log and prediction of the position of the water table. Read more..
