Let's review your options for cost and time savings.
As the demand for energy grows, oil and gas producers are drilling in more remote locations than ever before. These sites are often extremely challenging to reach since they, and the access roads leading to them, are often built on top of poor soils with weak, underlying subgrades.
When subjected to continuous, and often very heavy loads, these site access roads and laydown yards can quickly deteriorate, thus negatively impact both time-to-completion and long-term maintenance. And, when you can't reach the drill pad on-time and on-budget, how are you going to improve your bottom line?
As one example, this chart compares the cost of constructing a one-mile access road using several different methods, considering both initial construction and expected long-term maintenance costs. How does your current method stack up?
Productivity suffers when well sites are built on sub-standard soils or downpours and winter thaws leave access roads a wet, rutted mess. Also, long-term pad performance and reduced maintenance costs are even more important today since there is repeated, heavier traffic on almost every pad. Fortunately, TriAx Geogrid technology significantly improves on-site soils by stabilizing the ground. By stabilizing the soils under access roads and well pads, bearing capacity is greatly improved and your operation can bear heavier loads while continuing to perform for longer periods of time.
TriAx Geogrid is the most advanced type of geogrid due to its triangular apertures and high profile ribs. The triangular shape allows loads to be spread over a wider area, lessening the impact of repeated and heavily-loaded traffic. Using Triax will mean less differential settlement and less ponding of water on virtually every site.
All-weather, uninterrupted access to, from and around your well site, compressor stations, tank batteries, and laydown yards can be a reality. TriAx Geogrid is used in oil and gas construction to cost-effectively stabilize the soil that supports your structures and traffic. This significantly improves the performance and longevity of these surfaces, while drastically reducing your fill, haul and water requirements. And, because surfaces stabilized with TriAx Geogrid can support heavier loads, they continue to perform for longer periods of time and with less maintenance, ultimately saving you time and money.
How do geogrids work? Geogrids have openings, called apertures, which allow aggregate to strike through and provide confinement and interlock. Geogrids can improve the long-term performance of paved and unpaved roadways by minimizing aggregate movement and maintaining modulus values.
Tensar has designed a "Subgrade Improvement Pocket Card" that allows you to visually estimate subgrade strength. You can also use it to quickly determine your cost to improve the subgrade by using
common methods like over-excavation, geotextile and geogrid.
Tensar TriAx Geogrid has been tested extensively to ensure
long-term performance and value.
Your reputation is at stake anytime your stamp is used on a design. At Tensar, we don’t take this lightly. That’s why we have invested extensively in research and testing of our TriAx Geogrid, proving its design and performance parameters time and again. You can use your stamp with confidence every time TriAx Geogrid is specified in a design. Don’t risk using products with unproven technologies.
SpectraPave software provides roadway designers the most powerful tool available for evaluating options and optimizing performance using Tensar Geogrids. This free program specializes in the optimization of unpaved and paved roadway designs as well as the stabilization of construction platforms.
TriAx Geogrid has helped owners and operators around the world optimize their designs to get the longest service life for their budget. Due to its ability to efficiently confine aggregate, TriAx reduces the required aggregate while improving the overall performance. Here are just a few examples:
Our system approach to construction means that we'll partner with you throughout your project's lifespan – from planning and design to installation and on-site consulting – to help cut labor and material costs and get the job done faster. You will experience the convenience of having a supplier, design service, and site support all through one streamlined source to support your project needs.
