ABSTRACT:
A controller for gas-oil well installations which is microprocessor driven and compiles a datalog which is accessible locally for operator use. Customized microprocessor control for a given well installation is available on a practical basis by resort to the employment of a program approach utilizing bit-string patterns selected from a relatively large sequence of predefined well installation operational parameters or variables which have been identified. The masking and pattern recognition approach permits the handling of relatively large amounts of data and greatly simplifies the customization of well programming. This programming facility permits remote alteration of programs either by telephonic communication or by networking of a plurality of controllers within a given oil field. The programming feature is complemented by the utilization of a variable opening control over a motor valve.
