Introduction As we approach the new millennium, the era of the paperless office is becoming a reality. In line with this trend, the Alberta Energy and Utilities Board (EUB) implemented the requirement for Electronic Submission (ES) of well test data, by e-mail, effective March 1, 1999. This is the culmination of a long-term joint initiative by industry and the EUB. Although the implementation of this electronic process will allow the EUB to substantially improve its services to industry, many companies are struggling with acquiring the "know-how" of ES. In this article, attempts are made to remove some the ambiguities related to ES including software, hardware, and file format requirements. EUB Database History The EUB has one of the most comprehensive databases of the petroleum industry in the world. The number of pressure and AOF tests in the database and on microfiche are estimated at around 500,000 tests, with an additional 300,000 DSTs, that date back to 1945. In the past, a summary of each test was keyed into the EUB database, and the entire report was stored on microfiche. This process is slow and labour intensive, which resulted in a backlog of data delaying its availability. Furthermore, data retrieval from microfiche is tedious, and does not capture the electronic capability of the data. In the situation where well test data was required to be re-analyzed, data from the microfiche was difficult utilize. In the early 1990s, a joint industry/EUB committee discussed the standards and methods of well testing and data storage, as well as current and future needs. The concept of ES and dissemination of data evolved from these discussions. A system was defined to meet the following criteria:Acceptable standards to all companies, agencies, etc.Simple and user friendlyEasy and affordable accessibilitySecurity of confidential informationCompatibility with EUB legacy databases The committee had several public meetings to obtain industry's feedback, and the EUB agreed to proceed with ES in 1995. However, government funds were not available until late 1997. On July 1, 1998, the EUB went into production with ES of well test data on a voluntary basis. The deadline of January 1, 1999, for full implementation of ES for well test data was extended to March 1, 1999, to give industry more time for preparation. The infrastructure developed for ES has an 80 GB " jukebox," with ability to expand to 320 GB. A search engine has been designed for retrieval of electronic data, with selection available by UWI, test type, area, field, pool, operator, date, etc., or any combination. Overview of Electronic Submission (ES) In order to standardize the ES process, the EUB now requires all producing companies to provide well test data using only the "PAS" file format (Pressure Ascii Standard). Since no other file format will be accepted by the EUB, it is imperative to comply with this rule.
