For data managers and petrophysicists struggling to understand older well logs, the Denver Well Logging Society (DWLS) has made its Historical Collection of Wireline Charts available on CD-ROM.
The DWLS has compiled a collection of most of the logging company charts published between 1947 and 1999. The collection is now available as a seven CD set from the Society of Professional Well Log Analysts (SPWLA). The CD set is said to be an invaluable reference source for anyone analyzing logging data from the past 50 years. More from www.spwla.org.
