DigitizeIt - Extract data values from graphs in image form!

Sometimes it is necessary to extract data values from graphs, e.g. in most scientific publications only plots but no data values are published. DigitizeIt makes it easy to actually get back numbers from such a plot! This is a three step process: a) import the graph from a file or copy it over the clipboard, b) define the axes system, c) digitize it automatically or manually. Data values can then be saved in ASCII format or copy & pasted directly into any other application, e.g. MS Excel or Microcal Origin.

Riser Booster Pump

In some cases, an additional mud pump is designated as a riser booster pump and is used in the annulus to help bring cuttings to the surface instead of being used for extra horsepower on the hole. The riser booster pump sends fresh mud into the riser to dilute cuttings, which is especially helpful when drilling in deepwater.
