Horizontal Directional Drilling (HDD) is a method of installing underground pipelines, cables and service conduit through trenchless methods. It involves the use of a directional drilling machine, and associated attachments, to accurately drill along the chosen bore path and back ream the required pipe.
The application of TOB-TECH Horizontal Directional Drilling Rigs enables parallel installations in lengths up to 3000 meter at 30-40m depth with undercrossing rivers or water courses being common practice.
We undertake the process of finding and agreeing to terms, and acquiring goods, services, or works from an external source, often via a tendering or competitive bidding process. Procurement is used to ensure the buyer receives goods, services, or works at the best possible price when aspects such as quality, quantity, time, and location are compared. Corporations and public bodies often define processes intended to promote fair and open competition for their business while minimizing risks such as exposure to fraud and collusion.
We are focused in the procurement of HDD Rig Accessories (Bentonites, Reamers and flycutters, drill rods, drilling cables etc).
Phrases like ‘well-established method’ and ‘cost-effective, efficient application’ are often used to describe Auger Boring, widely used for the installation of steel pipes and casings.
Often called the ‘Jack and Bore Method’, this economical pipe installation method can be used in a variety of ground and environmental conditions, yielding many benefits from reducing traffic disruptions and roadway pavement damage to reducing noise and pollution concerns.
A properly designed and maintained drilling fluid performs essential functions during well construction such as transporting cuttings to the surface, preventing well-control issues and wellbore stability, minimizing formation damage, cooling and lubricating the drillstring and providing information about the wellbore.
Maintaining the optimal drilling-fluid density not only helps contain formation pressures, but also helps prevent hole collapse and shale destabilization.
TOB-TECH's capability in its core business areas have helped support the oil and gas industries by bringing together employees with technical expertise in various related fields.
