The phrase "about borehole" is not correct and lacks clarity in written English.
It may be used in contexts discussing topics related to boreholes, but it requires additional context to be meaningful.
Example: "The report is about borehole drilling techniques and their applications in geology."
Alternatives: "regarding borehole" or "concerning borehole".
Only boreholes with high flow rate (>8 l/s) (about 68 boreholes) were used in the rest of the analysis and randomly divided into two sets using MINITAB 16 software.
The proper interpretation of the experiment requires the right hypothesis about the borehole disturbed zone.
The simultaneous use of dilution and overcoring data provides accurate parameter estimates in the presence of measurement errors, allows the identification of the right hypothesis about the borehole disturbed zone and diminishes other model uncertainties such as those caused by errors in the volume of the circulation system and the effective diffusion coefficient of the filter.
But there are many unanswered questions about the borehole strategy.
(2) Vertical fracture is symmetrical about the borehole and vertically penetrating the formation.
However, they were not indifferent about where a borehole was built; neither were they indifferent about whether their respective companies built a borehole in the first place.
It estimates that London will eventually need about 50 boreholes.
About 500 boreholes, with depths of 5 to 20 m, were drilled and cored for analyses, and the frozen-ground conditions were evaluated.
The risk model was validated by comparison of its predictions with observations of MTBE detections for about 1100 boreholes in England and Wales.
In particular, the study has regarded the evaluation of site effects in correspondence of the database of about 1200 boreholes and water-wells available in the data-bank of the Catania area.
