Key Interpretations from the Attached Log:

•Gamma Ray (Track 1): Identifies lithology. Low GR indicates clean sand (our reservoir), while high GR points to shale.

•Resistivity (Track 2): Differentiates fluids. High resistivity signifies hydrocarbons (oil/gas), and low resistivity indicates water (brine)

•Integrated Analysis (Track 3 - Porosity Logs): Combining GR and Resistivity with porosity logs allows us to precisely identify fluid contacts (Gas, Oil, Brine) within the sand interval Notice the distinct responses for Gas (high resistivity, density/neutron crossover), Oil (high resistivity, less crossover), and Brine (low resistivity)

Soon after drilling into the earth’s surface, you cannot fathom what a borehole contains. Even the most experienced driller shall not be able to predict what lies in the depths of the cavity that stretches deep beneath the ground. Hence well logging is one of the best means to ascertain what the newly made borehole contains. This blog further expounds on the process of well logging.

• Discovering the borehole composition It is not uncommon for these cavities to be over a hundred feet in depth. Therefore, it is natural that the extraction of information demands due diligence. The process of gauging the content of these boreholes is vital so as to determine whether or not they hold within them any valuable minerals or extractable resources. While a number of methods are used to determine the content, these are known as creating well logs. The advancement of technology has presented new and faster ways to extract data in the form of advanced tools and software.

• Analyzing contents of the log While well logging you maintain a record of the contents of the fissure for a closer scrutiny. Geologists then hunt for details about the type of rock, the elements and resources found within. The rocks are analysed for porosity after which the logs are checked for liquids found inside the borehole as they must be investigated.
