Temperature Anomaly Mapping provides a cost effective and accurate method for determining presence of subsurface hydrocarbons. Surveying accomplished in the early morning can provide analytical results the same day. After data acquisition is complete, data is downloaded to a desktop computer for calculations and charting analysis. What would the value proposition be if results are presented real-time while the surveyor is logging the data? Table 1 provides a summary of those benefits.
The advancement of computer technology in the last two years has dramatically improved desktop computing power for mathematical and scientific analysis. This enables further refinement and additional of features of TAM (Temperature Anomaly Mapping) Services for scientific analysis. The thermal surveyor has the ability to view the mathematical analysis of the survey in real-time while performing mobile data acquisition.

Real-time logging of corrected survey data provides intelligence for prospecting adjacent survey areas and correlation of converging areas of interest. Real-time presentation of the thermal log provides a visual reference to the accuracy of data, including sensor performance, accuracy, and atmospheric changes. The real-time chart provides a visual explanation of what the surveyor may already recognize through his senses.

Exploration Architecture Overview Simplified Field Operations Software and hardware tools that have a simplified learning curve without special programming provides a significant advantage to the user. These tools provide easy manipulation of raw survey data in real-time. Survey recording templates and programs can be preprogrammed, and selected for use during various portions of the data collection or survey type. These simplified processes allow the surveyor to focus on the survey area and attributes. Using car mounted laptops, the surveyor can monitor the results during the survey. Hands free viewing provides an auto-pilot type control for easy log monitoring. Data integrity and storage are accomplished using USB or compaq flash based data storage. The block diagram labeled Figure 2 provides a hi-level view of the real-time architecture. Sensors

Figure 2 Web Based Presentation Web page presentation of raw and corrected data via TCPIP connectivity to the data logger can be easily configured. This enables the use of Flash-based charting tools. Adobe Flash is available on 90% of the computers today with low memory overhead. These flash based charts can be easily stored using XML based tables and reference files. This allows easy retrieval over the web, or from the user’s locally stored data files. Standard web-based browsers such as Internet Explorer are utilized. With proper mobile connectivity, these flash based charts can be easily uploaded and viewed remotely by customers or for later customer or survey analysis retrieval. Enhanced post survey analysis Specialized data analysis of survey sections can be accomplished using customized charting software. Common and frequent chart presentations can be saved as templates for simplified chart building processes. XML based data storage is the method of choice for real-time and post analysis chart data organization.

Geo-Reference of Survey data The affordability and simplified integration of GPS technology for surveying has improved recently for COTS (commercial off the shelf) mapping tools and survey equipment. Handheld GPS devices are readily available for viewing survey areas on a color LCD monitor. Georeferenced surveys provide a vantage point for the surveyor to make annotations of the survey area. Use of handheld data collection methods can be used where a closer look at thermal anomalies are required. Indexing of survey points for retrieval Thermal data referenced to GPS coordinates, can provide a reference location for search and review at a later date. The field surveyor that performs the work may or may not be the scientist evaluating the survey data. Start and stop times, waypoints, and notes of interest including summaries are easily indexed while performing the thermal survey. GPS index points can be easily inserted in the chart data for later reference.
Words from a legend In my opinion, the time has come for the adoption of radical and aggressive methods of prospecting, and a fraction of the money wasted yearly in drilling shallow wells in hopeless locations might well be devoted to this purpose. Anthony Lucas, September 1918. Colorado Meeting. American Institute of Mining Engineers.
Expert Comments An exhaustive Alberta, Canada study shows that temperatures below oil and gas fields are 15ºF – 34ºF warmer than the average values observed outside of the fields. A scuba diver reports a 58ºF temperature at a water depth of 60’ in Lake Superior off Michigan’s Keewenaw Peninsula. Because the water temperature at that depth for that area is about 40ºF, it is likely that the temperature anomaly is the result of a buried copper deposit. Jerry Whittaker, former V.P., Canadian Hunter stated that temperatures of 200ºF to 250ºF are prevalent below major gas fields in Canada where the average non-field temperatures at the same depths are only about 160ºF to 180ºF. His stated relationship was “The bigger the field, the greater the temperature anomaly.” A Michigan study shows that undrilled Prairie DuChien commcial reservoirs can be discovered by the processing of existing shallower temperature data.

Information about the Science E. DeGolyer in 1931 stated: “In the coastal fields of Texas and Louisiana, a rapid increase in temperature of 10ºF to 20ºF, or even more, is always noted before water makes its appearance in flowing wells.” Again, in 1931, E. DeGolyer reports flowing oil temperatures from Mexican Eagle, Portraro DeLano #4 as 102ºF when flowing at a rate of 100 BPTD, 133ºF when flowing at 30,000 BOPD and 149ºF at a flow rate of 100,000 BOPD. The depth to the pay zone was 1911’.

[email protected] This white paper summary highlights the benefits of realtime data logging architecture for temperature anomaly surveying and mapping.
When newly drilled wells are spotted on old temperature anomaly maps, the relationship between ‘old’ prospect exhibiting negative anomalies to new discoveries is near perfect. Temperature anomaly maps, when compared with developed field structure maps have been shown to exhibit startling similarity as indicated by Louisiana’s Irene Field example as presented to me by Phylko’s Don Timko. Average Seismic Costs: $3,000 per mile, vibrator in East Texas $8,000 per mile using dynamite in the Gulf Coast $25,000 per mile, Louisiana swamps $40,000 per mile, Gulf of Mexico Average Seismic Success: 10%, Eastern Colorado (Masters) 20% Overall (Robert Snyder) 35-40% Manistee County, Michigan (Mike Bricker)* 15% overall (Bill Wilfong) *There is a success rate of 35% in Manistee County, with or without seismic. $40,000 per mile, Gulf of Mexico Errors in Operational Publications used today The old definition of thermal conductivity is incorrect and misleading, in the Encyclopedia Britianica and Remote Sensing in Geology. The “International Organization for Standardication” changed the definition in 1992, not to limit the heat transfer to conduction.
Conclusion With America’s need to find more oil accurately and cost effectively; Temperature Anomaly Mapping provides a very favorable value proposition for reducing dry-hole percentage. Real-time survey functionality that provides ease of use and scalability can enable field operation teams the necessary momentum for documenting vast areas of unproduced land. Real-time calculation and analysis has the potential to exceed expectations for the
