Abstract A method for maintaining in a computer memory laboratory test records for a plurality of projects, particularly adapted to projects for cementing oil or gas wells, are disclosed. Records of data identifying the plurality of projects and records of test data for the plurality of projects are entered within the computer memory. Data from selected records are compiled in a predetermined report format. More particularly disclosed is a method of designing a cement job for an oil or gas well. This includes receiving into a computer, programmed with records of data in predetermined categories for a plurality of previous cement jobs, a field of search for a selected predetermined category of data pertinent to a cement job being designed. Automatic searching within the computer finds records which contain data within the field of search. These are displayed. Design data are selected in response to the displayed records and the design data are stored in the computer in a record for the cement job being designed. Modifications can be made if desired after the initially defined design has been tested. Also disclosed is the direct entry of test data into the computer from test equipment in which a selected design has been tested.
A method of designing a cement slurry for an oil or gas well in a computer system having a display, comprising the steps of: cataloging substances used in cement slurries for oil or gas wells; grouping the cataloged substances by types; storing in said computer system encoded signals defining a first set of distinct records of the grouped types of cataloged substances, wherein each said record identified the substances of a respective type; determining properties of a plurality of actual cement slurries, said determination being performed by one of experimental and historical means; storing in the computer system encoded signals defining a second set of distinct records identifying the plurality of actual cement slurries and their respective determined properties, and including at least one of the stored cataloged substances from the first set of distinct records; entering into the computer system, via a sequence of successive input selecting menus appearing on said display a field of search for a cement slurry to be designed for an oil or gas well, the field of search including at least one of the types of cataloged substances and properties and in automatic response thereto, searching the stored records by said computer system and displaying on said display stored records having entries within the entered field of search, wherein the displayed records are from at least one of the first and second sets of distinct records; and selecting a design cement slurry in response to the displayed records.
