3 ways continuous ground-gas monitoring saves you time

Read More

Ground-gas monitoring programmes can hold up brownfield development. Spot monitoring periods can be prescribed for up to 12 months. Continuous monitoring can provide a solution to this.

Continuous monitoring involves the use of unmanned data collection instrumentation. There are many benefits to collecting continuous data, including improved risk prediction, but continuous monitoring also saves you time. Here’s how:

The Onshore Energy Services Group Publish a Series of Factsheets

Read More

The onshore energy services group (OESG) have a series of factsheets published on their site to inform on aspects of the oil and gas industry. Each factsheet provides a very useful resource for policymakers and public stakeholders to understand the processes of extracting energy, along with the risks, the safeguards employed to protect against these risks, and the regulatory framework within which oil and gas extraction takes place.

 

All the factsheets can be found on this link www.oesg.org.uk/resources/factsheets

BS8485 Code of Practice Revision

Read More

The revision of BS8485 Code of practice for the characterization and remediation from ground gas in affected developments is underway and the draft has now been released and is available to view and comment here: http://drafts.bsigroup.com/Home/Details/54404 .

 

The draft incorporates significant additional technical information from its original and introduces changes and clarifications to the scoring matrix for gas protection.  Verification in line with C735 is included within the draft.

What does continuous monitoring mean?

Read More

Continuous ground-gas monitoring is a popular method for certain situations (see previous article on ‘when to use continuous ground-gas monitoring’).

This article tries to answer the question: what does continuous really mean in the context of ground-gas monitoring?

The Oxford English dictionary defines continuous as: Forming an unbroken whole; without interruption.

Traditionally, the contaminated land industry has relied on ground-gas monitoring results collected at a frequency of 1-2 weeks.

EIC publish their position paper on tackling the risk of Radon

Read More

Peter Atchison, Chairman of EIC Contaminated Land Working Group says “The health risks from exposure to high levels of radon have been well-understood for many years, but the issue remains low in terms of public awareness or political focus. EIC has produced this position paper on radon to raise awareness of both these risks and the actions that can be taken to mitigate them among government, regulators, developers, building owners and occupiers and related professional advisers. EIC’s aim is to present a balanced picture of risks and mitigation opportunities to avoid unnecessary anxiety

GGS presented at UKTI Low Carbon R&D seminar, Warsaw

Read More

The British Embassy in Warsaw hosted a Low Carbon R&D seminar last Thursday on the 5th February 2015.  The full day event provided an overview of low carbon products and services and promoted on-going R&D projects as well as looking at collaboration opportunities between British and Polish partners. A link with more detail and photographs can be found here:

 

The seminar was divided into two parts, the first part of the day focused on ACUMEN, where Andrew Brunton of GGS presented an

Ground gas flow and continuous monitoring

Ground-gas flow and continuous monitoring

I’m often asked: Does GasClam® measure flow?

This article attempts to answer this question and highlights the reasons why flow measurements may sometimes be misleading.

“No…”

GasClam® does not measure flow. In order to measure flow directly, a valve must be released which allows ground-gases (or air) to move from borehole to atmosphere, or vice versa. GasClam® is sealed into a monitoring well throughout monitoring and therefore no gas flow passes from ground to air. Options are available to intermittently release gas to the air, rather than recirculate to the borehole, but flow is not recorded as it passes through.

When is continuous ground-gas monitoring beneficial?

Read More

Continuous ground-gas monitoring can be a powerful tool in better understanding the ground-gas regime. However, it is not always necessary and sometimes we can figure out what we need to know through comparing periodic monitoring data with our Conceptual Site Model.

This post sets out some of the situations where continuous ground-gas monitoring may be a good option.
