This paper presents a user's view of well-data systems and gives the historyof their development within one company. In 1951, Imperial Oil Limitedestablished a punched-card system for well data. In 1958, this system wasabandoned when it was decided to go ahead with the development of acomputer-based well-data system with the data stored on magnetic tape. By 1963,this system contained basic factual data and geological tops on everyone of the37,000 wells drilled to that time in Western Canada. Since then, another 7,000wells have been drilled. Data on these, as well as changes to existingdata, are being added as they come in every month.
With regard to the design of the well-data systems, the paper makes twobasic points. First, the users of technical-data systems such as the onedescribed must take an active part in their design, development and operation.This is more important in this type of system than in a business-data system,which does not require the same flexibility in answering requests. Second, awell-data system should be restricted at the start to basic factual data, andextreme care must be taken to ensure that only reliable and useful datacontinue to be included. Otherwise, the system will lose the confidence of itsusers and will ultimately fail.
On the subject of economics, if the evaluation of technical-data systems isconfined solely to the unit costs of storage and retrieval, these costs willprobably be judged to be fairly high and therefore the system not economic.However, the value goes beyond this analysis, and the worth of technical timeis considered to be a much more important and sensitive factor. Despite thedifficulty of evaluation in dollars, this advantage probably makes theinvestment in the system worthwhile.
