This paper describes the formulation and operation of a Reserves and Economic Analysis program written for micro-computers. The program was constructed as a template to be used with spread-sheet program was constructed as a template to be used with spread-sheet software. The version being discussed in this paper uses a popular commercial software program called 1-2-3* which was written for the IMB-PC** or compatible machines.
Being a spreadsheet template, this program can be converted to other software and/or hardware systems. It also offers the user a high degree of formatting flexibility, which can be used to create customized in and/or output for specific purposes. Other advanced facilities available in 1-2-3 such as "Self-Explanatory" Menu and "User-Defined-function" Macro make the program user friendly.
The logics and instructional equations of this program is relatively compact and efficient in terms of hardware requirements, processing speed and accuracy. processing speed and accuracy. This program can be utilized for most projects that involve reserves and economic analysis, for it offers many of the options available on much larger commercial packages. Some of these desirable options include a third phase of production, automatic scheduling of the decline rate and the production stream, two payout conversions in cumulative dollar or volume of the primary phase, changing secondary and/or tertiary phase(s) to primary phase ratio and manual inputting.
The economics of the system, whose cost includes the minimum hardware and software requirements, are also discussed by comparing the cost of running numerous cases on this system versus runs on a commercial timeshare system.
The program will be in the public domain. Its listing and an operator manual can be obtained through the authors or the Energy Engineering Department of First City National Bank of Houston for the distribution cost.
If we were to characterize the technical advancement of a society through the computing power available to its office workers, most, if not all of us, will have to agree that in the last twenty years or so, our society has made a giant forward leap, and this was particularly true for the last couple of years, during which the particularly true for the last couple of years, during which the proliferation of desk-top microcomputer was practically bringing proliferation of desk-top microcomputer was practically bringing unimaginable calculating speed and accuracy to (almost) everybody's fingertips.
Prior to the arrival of high power and compact calculating devices Prior to the arrival of high power and compact calculating devices such as the desk-top computers, the engineers were placed in sort of a dilemma. We all realize that many of our daily tasks, most of which involve hundreds of calculations, may not deserve the treatment of a mainframe (or mini) computer, yet they are definitely too large to be worked out by hand (with or without a calculator). In these occasions, we were forced to use the mainframe and to go through the mainframe inconvenience, only wishing that an intermediate device was available to save our time and the computer time.
The micro-computer answers our wishes for that intermediate device. It is a crossing between the impotent hand-held calculator and the bulky mainframe machine, and it can offer both computing power and portability. For most practical purposes, the micro's computing portability. For most practical purposes, the micro's computing power provides the user plenty of maneuvering space that is not power provides the user plenty of maneuvering space that is not available in a calculator, thus brings it closer to the ability of a mainframe computer.
