As more utility contractors are moving up to larger rigs, they are also moving toward the use of solids removal (solids control) systems.

In the past few years, there has been incredibly innovative technological advancements in the horizontal directional drilling industry.
The mud pump used on most directional boring machines is either of the piston/liner or plunger/packing technology.
A modern horizontal directional drilling machine is a combination of several different systems, and every directional drilling installation depends on all systems functioning smoothly.
We all know what “back reaming” is-make a bore, remove the bit, install a back reamer or hole opener and ream back to the boring machine.
It is often debated whether the locator or the drill operator is in charge of directionally drilling a pilot hole. The truth is that they are both responsible.
Bentonite-based drilling fluids are used in both vertical and horizontal drilling. The desirable drilling fluid properties, however, are different.
Directional mud motors are the most proven and common method utilized by HDD contractors to complete installations in hard rock formations.
The benefits of pumping greater volumes of fluid (mud) while boring are rapidly gaining favor from most horizontal directional drilling contractors.
There seems to be a certain amount of confusion about the role of drilling fluids in horizontal directional drilling, especially under roads, streets and highways.
In a short time, some drilling contractors have grabbed hold of the technology and are making really good money.
Alocating system is an integral part of the HDD process and it represents a substantial investment, ranging from about $10,000 to $20,000.
When a contractor calls about a drilling fluid problem, he’s sometimes surprised when we seem to ask questions about what seems to be everything except drilling fluid.
One of the hot new topics in the horizontal directional drilling industry today is fluids recirculation and reclamation.
Expendables such as valves, plungers, packing, pistons and liners are exactly that: expendable. Over time these items will wear out and will need to be replaced.
In recent years the advancement of technology in the electronics field has made electronic equipment the key element in the viability of directional drilling.
Reamers and pocket knives are both cutting tools with about as many sizes, shapes and descriptive names for one as the other.
You’re in the middle of a backream operation and everything is going well. You lose flow. Gradually your reverse thrust pressures increase until you run out of pulling power.
The Trenchless Technology Road Show completed a successful two-day conference May 14-15. The event, organized by Trenchless Technology, was held at the Hilton Lisle/Naperville outside of Chicago. The conference, sponsored by NozzTeq Inc., Sunbelt Rentals and RJN Group, attracted attendees from all across North America.
