Where can I find well logs?

Depending on your location, your state or county health department, Department of Natural Resources, or some other similar agency may house well logs that you can access or request a log from. If you know who drilled your well, it might be a good first step to contact them and ask for your log.

Then, where can I find well information?

Any questions concerning the Alberta Water Well Information Database or Alberta Water Wells website can be directed to the Groundwater Information Centre by e-mail, at , or by telephone, at 780-427-2770.

One may also ask, where can I find well information in Montana? Well data is updated continually at GWIC. Current data for any well, or updated data sets, can be obtained directly from the GWIC website at The Montana State Library provides this product/service for informational purposes only.

In respect to this, what is a well drillers log?

Well logs, sometimes called drilling reports or water well records in some states, all contain the same basic information. All well logs contain a unique well reference number, the owner's address, the location of the well and the construction and contractor details.

What is meant by well logs?

Tweet. Well logging chronicles the depths, subsurface formations and events encountered while drilling. Well logs can include visual observations or be made by instruments lowered into the well during drilling. Tradition holds that the term "well logs" is borrowed from ship nomenclature.

How do I find the water table in my area?

The most reliable method of obtaining the depth to the water table at any given time is to measure the water level in a shallow well with a tape. If no wells are available, surface geophysical methods can sometimes be used, depending on surface accessibility for placing electric or acoustic probes.

What should I look for in a well report?

The EPA recommends:
  • Periodically inspect exposed parts of the well for problems such as: cracked, corroded, or damaged well casing , broken or missing well cap , settling and cracking of surface seals.
  • Slope the area around the well to drain surface runoff away from the well.

How do I know how deep my well is?

Carefully drop the weight into the well and lower it until it stops dropping. Take up the slack and mark the string at ground level. Pull up the weight from the well and measure it from the bobber to the mark, and that will be your depth to water, or head.

What are the types of well logs?

The standard well logs are the temperature log, the caliper log, and the resistivity log.

What are well logs used for?

Well logging is used for electrical imaging, mine mapping, and hydrocarbon and hydrological exploration to obtain in situ properties of possible reservoir rocks. Electric logs are considered useful for evaluating formation fluid properties.

How many types of well logging are there?

Four types will be described here: acoustic velocity, acoustic waveform, cement bond, and acoustic televiewer. Spontaneous potential (SP) is one of the oldest logging techniques.

How do I put a well on my property?

The Step By Step Process Of Well Installation
  1. Step 1 – Picking the Spot. The first step of building a well comes with an initial consultation period.
  2. Step 2 – Drilling The Well.
  3. Step 3 – The Casing.
  4. Step 4 – Screens.
  5. Step 5 – Grouting.
  6. Step 6 – Cleaning/Developing.
  7. Step 7 – The Final Touches.

How do I get a well completion report?

To request copies of this pamphlet, write or call DWR's Publications and Paperwork Management Office, P.O. Box 942836, Sacramento, CA 94236-0001, (916) 653-1097 or imr-publications@water. ca.gov. Copies are also available at: ca.gov/wells/.

How do you read an oil well log?

Follow the Ko Ko Rules:
  1. Tight non-reservoir: Right-Right-Right-Right.
  2. Shale: Right-Right-Right-Left.
  3. Low porosity (tight) reservoir: Left-Right-Right-Right.
  4. Water bearing reservoir: Left-Left-Left-Left.
  5. Oil bearing reservoir: Left-Right-Left-Left.
  6. Gas reservoir: Left-Right-Left-Right.

What is well completion report?

California Water Code Section 13751 requires that anyone who constructs, alters, or destroys a water well, cathodic protection well, groundwater monitoring well, or geothermal heat exchange well must file with the Department of Water Resources a report of completion within 60 days of the completion of the work.
The State of California does not regulate water quality in private domestic wells. The Division of Drinking Water regulates the water quality in public water systems.

How much does it cost to dig a well in Montana?

Drilling a well costs anywhere from $25 to $29 per foot. Throw in another couple of thousand to cover the pump and pressure tank. A standard gravity-flow septic system will usually run between $3,500 and $5,000, and engineered septic systems can go up to $7,000.

What is static water level?

Static water level refers to the level of water in a well under normal, undisturbed, no-pumping conditions. Static water level is best determined when the well has not been pumped for several hours prior to measuring.

What do resistivity logs measure?

Resistivity logging is a method of well logging that works by characterizing the rock or sediment in a borehole by measuring its electrical resistivity. Resistivity is a fundamental material property which represents how strongly a material opposes the flow of electric current.

What are wireline logs?

1. n. [Reservoir Characterization, Formation Evaluation, Drilling] A continuous measurement of formation properties with electrically powered instruments to infer properties and make decisions about drilling and production operations.

What is open hole logging?

Open-hole logging refers to logging operations that are performed on a well before the wellbore has been cased and cemented. In other words, the logging is done through the bare rock sides of the formation.

What is porosity log?

The "Porosity" logs. There are three types of logging tools that are used to estimate the amount of pore space in a rock: the neutron, density, and acoustic velocity (or sonic) tool. So, the log is mainly a measure of hydrogen concentration (mostly contained by the pore fluids of the formation).

What is a geophysical log?

Geophysical logging provides measurements of a wide variety of parameters down the length of an open borehole or cased monitor well, similar to the surface geophysical methods (Fig. 18.1). Geophysical logging is commonly used in the oil and gas industry as part of exploration and development.

What is production logging tool?

Definition - What does Production Logging Tool (PLT) mean? A Production Logging Tool is any instrument that is used in the preparation of production logs. These tools are run through wells that are complete and ready to operate.

What is electrical well logging?

Introduction • Well Logging involves measuring the physical properties of surrounding rocks with a sensor located in a borehole. The record of measuring as a function of depth is called as well logging.
