6 FAQs about [Rock drill pressure measurement video]

How does geophysics affect drilling?

It affects probe drilling, grouting rock reinforcement and last but not least safety. There are several methods to gain information, such as geological mapping, analysis of drill cuttings, diamond drilling, bore hole geophysics, single rock samples, visual hole inspection and MWD (Measure While Drilling).

What is a universal pressure tool?

Probe-based universal pressure tool measuring ringed and pipe pressure in real-time. Scientific Drilling’s Universal Pressure Tool (UPT) is a probe-based pressure sensor measuring ringed and drill pipe pressure. Fully integrated with both MP-MWD and EM-MWD systems.

How does Sigra measure rock stress in boreholes?

Sigra undertakes rock stress measurement in boreholes using its IST overcore system, which is suitable for holes up to 2000 m depth. It also undertakes hydrofracturing for stress measurement and analyses borehole breakout data.

How do you get information about a drill hole?

There are several methods to gain information, such as geological mapping, analysis of drill cuttings, diamond drilling, bore hole geophysics, single rock samples, visual hole inspection and MWD (Measure While Drilling). The MWD technology consists of two separate processes: registration of data and evaluation/interpretation of data.

What are the limitations of a vertical drilling tool?

As the tool is normally used in vertical drilling from surface the assumption is usually that the vertical stress is that of overburden weight. Where this has the most limitation is within zones where reverse faulting leads to areas of increased vertical stress and adjacent zones of reduced stress.

How do you drill a pilot hole?

It involves pulling the core, then in place of the inner barrel a stump grinding and countersinking bit is run and used to remove any upstanding core stump and centralise hole for the subsequent pilot hole. This is withdrawn and a pilot hole drill is used to create a hole 500 mm long and 25.5 – 26.5 mm in diameter.
