Site Investigation Guidelines for Directional Drilling Projects

 

Subsurface information is of utmost importance for contractors and engineers working on Horizontal Drilling projects so that future projects proceed as planned. The explorations prior to horizontal drilling projects are considered here in a broad sense: they include collection of geological, hydrogeological and geotechnical data, as well as hidden natural or artificial obstacles, which can interfere with the drill path.

 

Use of directional drilling techniques is increasing around the world. As in any construction project, it is necessary for the contractor to have as much information as possible to prepare a competitive and comprehensive proposal and to be able to successfully install the crossing. Better preconstruction information also allows the work to be undertaken more safely and with less environmental disturbance.
