” How To Easily Read A Well Log ” is step-by-step approach in interpreting any well logs. This is a technique I called ’The Ko Ko Rules’.
Is 20 gallons per minute a good well?
You could have a great well water flow rate – say 20 gallons per minute – but if it the water will only run at that rate for five minutes before you run out, the well has a very poor water quantity (5 minutes x 20 gpm = 100 gallons of water) and it’s not a satisfactory well.
How many gallons a minute is a good well?
5 gpm (two fixtures running simultaneously at 2.5 gpm) is a good estimate of peak demand, for the typical household. Water wells that reliably yield 5 gpm should be able to meet peak and daily needs for most residences. Wells yielding less than 5 gpm, however, are sometimes the only water source available.
How can I tell how much water is in my well?
You can measure the depth of water by lowering a wetted steel tape to into the well until the lower part of the tape is under water. A chalk coating on the last few feet of tape indicate the exact water level.
How is well recovery rate calculated?
The formula for determining well flow rate is: (Gallons drawn) divided by the (number of seconds timed for the pump cycle), then multiplied by 60 equals the gallons per minute (GPM) that your pump produces.
What is well logging interpretation?
Well logs present a concise, detailed plot of formation parameters versus depth. From these plots, interpreters can identify lithologies, differentiate between porous and nonporous rock and quickly recognize pay zones in subsurface formations.
How are well logs measured?
Caliper. A tool that measures the diameter of the borehole, using either 2 or 4 arms. It can be used to detect regions where the borehole walls are compromised and the well logs may be less reliable.
What is DT in well logging?
DT. Short-spacing delay time ( t) xb5s/ft.
How do you interpret porosity logs?
To obtain porosity, read the value directly from the log. If the log is recorded in limestone units and the formation you wish to evaluate is sandstone or dolomite, then correct the log value by using the appropriate chart in a log interpretation chartbook.
What can we interpret from well log?
Well logs present a concise, detailed plot of formation parameters versus depth. From these plots, interpreters can identify lithologies, differentiate between porous and nonporous rock and quickly recognize pay zones in subsurface formations.
How do you read an oil well log?
Well log analysis provides the information on petrophysical properties of reservoir rock and its fluid content.
What is well log analysis?
Lithology can therefore be interpreted directly from neutron values only when porosity is insignificant. In porous rocks, the neutron log must be interpreted in combination with other logs such as formation density.
What is petrophysical interpretation?
Petrophysics is the study of rock principles and their interactions with fluids (oil, gas, or water) (Rider 2002). Petrophysical interpretation transforms a well’s log measurements into reservoir properties (e.g. porosity, permeability, saturation, mineral component volume, and Vcl) (Bisht et al. 2013).
