Direct Push Technologies (DPT) have greatly increased the amount of data that can be generated from a single borehole. Direct sensing tools advanced by DPT methods provide information on both the subsurface physical parameters as wells as contaminant distribution. They have become the most widely used platform in the HRSC investigations of unconsolidated material. However, DPT technologies have limitations in their penetration depth, and with advancement in difficult subsurface conditions. These limitations are commonly referred to as early DPT refusal, which can leave gaps in conceptual site models and present issues for contractual obligations.
Through our wide array of available drilling technologies and subsurface experience, Cascade has several solutions to these problems. The solutions range from simple scope of work limitations and contract language to hybrid drilling methods. In this webinar, cover some of the solutions we have implemented and available configurations that can overcome these challenges.
