Appalachian Region


The Digital Revolution: Archive, Organize and Deliver

Traditionally, public oil and gas databases in the Appalachian basin have contained various parameters associated with site specific well locations, including tops, thicknesses, treated intervals, initial well test and pressure and production histories. More recently, individual reservoir data were compiled on a field scale for oil (TORIS) and gas fields (Gas Atlas). Recent effort compiled a variety of other data types (stratigraphy, structure, seismic, petrology, geochemistry and gas production) for the Trenton-Black River trend.

Basin-wide databases created during recent research projects include: digital maps, cross sections and other illustrations that were either works in progress or finished versions in reports and slides used for presentations. References from the literature and lab data generated during the projects also are included in this "new generation-style" database, one that captures in digital form all aspects of previous work as well as this new information (as an example, see page 7—12-CD set of DOE's unconventional gas research data).

In a recent Appalachian Region workshop, those involved in developing and delivering data described the "digital" systems and resources available for their state. These offerings are dynamic, so an update like this has great value for those operating in the region.

Speakers representing the Pennsylvania Geologic Survey (PGS) described and demo'd (1) the WIS (Well Information System) and (2) PA*IRIS (Pennsylvania Internet Record Imaging System). WIS originally was for internal use only, but evolved into a system that can be used by visitors to the PGS offices. Survey personnel help the visitors log on to find information on individual wells. PA*IRIS was developed to enable industry to access well records from their offices. Essentially, the PGS scanned everything in their files and put it into this system. An expensive software system is required to view the information, so the PGS charges each subscriber a one-time $5,000 fee, plus $500 for annual maintenance.

Originally PA*IRIS included scanned location plats, the completion record (drillers' log) and perhaps a plugging affidavit, but it has evolved since '99 to link to WIS, so more detailed information on an individual well can be accessed.

This includes interpreted information, such as log tops picked by staff geologists, plus lists of available logs, lists of "canned" reports with data in spreadsheets and a production module that allows the user to gather production data. ArcReader allows users to view tiff images of oil and gas base maps.

The PGS is planning several new products that will become part of PA*IRIS. This includes 7.5 minute topo maps with well locations, the ability to view several layers, download capability, interactive tools, etc. They plan 10-15 interactive layers that can be turned on or off, with print capability.

Staff from the Ohio Geologic Survey described and demo'd POGO, the Production of Oil & Gas in Ohio database that is updated annually; the digital map series; bedrock geology, on CD or online; and the interactive map series. Most of the time was spent describing the interactive map series, which includes the oil and gas maps in combination with topographic maps, aerial photos, roads and streams, etc. A print layout feature with scaling options allows you to create a PDF.

Searches can be made on many parameters, but most begin with the state permit number. Ohio has one file, one folder per well in their system, whereas Pennsylvania has separate files for the plats, well record, plugging record, etc. The Ohio system allows a user to cut and paste well data and create their own shape files. They also have a query string option, allowing a user multiple choices to add to the query string before the search is executed and the data are assembled in a table or on a map.

In New York there is ESOGIS (Empire State Oil & Gas Information System). Early punch card and tape systems eventually evolved into the online system of today. Their goal in NY was to make all subsurface data and information, including all of their reservoir studies, available online. This includes slides of numerous talks presenting results of research. To use the site, one first must create an account, then log in. Creating an account allows one to create different project files and then to add data to these files. There is no limit to the number of wells that you can download, but there is a one minute time limit on the downloads. A project manager feature allows one to create a project, add wells, tailor the data, display and download the data. Scanned images of well records, logs, etc. are available, as are production data. There is also a virtual core library, where one can look at core photos or core images. NYSERDA reports are also available there.

Subscriptions range from $2,500 to $25,000, depending on which of five levels one chooses.

Staff from the West Virginia Geologic Survey (WVGS) described their (1) oil and gas database and (2) a current project to assemble from a variety of sources all data on five tight gas plays and deliver the data online. Current online services include "pipeline," a subscription service that allows users to access data on individual wells; production summaries, where queries can be made by well, by county or by years; e-logs, as scanned images in tiff files; focused datasets, mainly from project work, like Trenton-Black River, coal bed methane, etc; and the IMS site, which is hosted by the WVGS. The idea in the DOE-supported Log Scan project is to find every piece of data on five tight gas plays in two states, organize the data into a database and delivery it to users online. This data is currently widely scattered among offices and even within offices.

Demonstrating their commitment to the digital world, the Kentucky Geologic Survey has taken a bold step of closing their oil and gas record room (open by appointment only) and replaced it with a system that can display everything in that room on a user's computer. To do this, the user needs to download and install a free web browser plug in. No fees are required and no subscription service is necessary.

Those looking for data should not forget Google. Its searches not only lead one to the resources within geological surveys and state agencies, but there can be other sources. When one finds a resource of value, bookmark it and it's easy to go there again.
