A computerized handbook known as an ‘i-Handbook’ is adapted to be stored in a memory of a computer
system and displayed on a display screen of the computer
system for assisting field personnel in the performance of their respective job related responsibilities. The ‘i-Handbook’, when displayed, has the appearance of a real handbook and it includes a
database and a plurality of calculators for calculating a plurality of oilfield or
wellbore related data in response to a first plurality of data in the
database and a second plurality of
data input by a user. The plurality of calculators are adapted for calculating: unit conversions, triplex pump volumes, tank volumes, tubular stretch and free point, annulus volumes,
slurry density, gate percentage, screen out,
cement slurry, casing lift, HCL density, oil gravity and API, and salt requirements. The ‘i-Handbook’ has a
wellbore diagram feature which will allow a user to draw and create differing types of downhole tubular, packers and perforations in the tubular adapted to be disposed in a
wellbore. In addition, the ‘i-Handbook’ can display: tubular capacities and displacement volumes, and tubular data based on suppliers which will enable a user to search through a
database of the tubular data to locate the suppliers. This abstract is provided for the sole purpose of aiding a patent searcher; it is provided with the understanding that this abstract shall not be used to interpret or limit the scope or meaning of the claims.
