The well logging process creates a detailed record of an oil or gas well's subsurface geology. Well logging information is a valuable resource for developing a detailed understanding of the volume of an oilfield, or to map the extent of gas deposits. After an exploratory well reveals the presence of oil or gas, detailed well logs are a critical asset for further exploitation of the resource.

A well logging provider can develop a well logging list, which can in turn be used to create a three dimensional model of the subsurface. Find well logging information from the area to determine the feasibility of more costly exploration. A mathematical analysis between the well logs and other geophysical data can be used to determine the best areas for exploration.

1. Hire a competent well logging provider to develop a complete record of all well logs in the area.

2. Use advanced technology to gather well logging data.

3. Perform a detailed analysis of well logging information in order to plot the locations of potential oil and gas deposits.

Action Steps
The best contacts and resources to help you get it done

Compare the portfolios of well logging providers before you hire

An experienced well logging provider can save a great deal of time and money in the development of new and existing oil and gas fields. Drilling a well is an expensive undertaking, and a qualified well logging provider can help a business target its assets in areas with the highest potential for a strike.

I recommend: Schlumberger is a world-leading provider of oilfield services. It can provide a fully-integrated, cost-effective well logging and related operations. Horizon Well Logging provides services for mudlogging and other wellsite related services. It's an internationally respected company with experience in the US and abroad.

Buy or rent well logging equipment from an industry leader

Well logging equipment can be customized by an experienced company to suit a site-specific need. The equipment should be easy to operate but also robust enough to hold up under harsh conditions. If possible, ask for an onsite demonstration of any unfamiliar well logging equipment before you employ it in the field.

I recommend: Drilling products from Sondex provide a method for measuring and well logging while drilling, which keeps your business competitive and increases efficiency. Geosearch Logging offers a full range of services for monitoring geological and hydrocarbon wells.

Incorporate data analysis tools into the well logging process

Reams of well logging information has little value until it has been analyzed. After the information is gathered it must be digitized and incorporated into a geo-referenced data analysis software program. The data modeling and visualization tools can then target the available well logging information.

I recommend: Geologix carries a full suite of well logging software and analytical tools. Its Geologger software has an easy-to-use interface that seamlessly integrates well logging data with the other programs. WinLog provides a quick and easy method for analyzing geological information from boreholes and well logs.
