Field-Applied Computerized Tracking System: A Practical Approach to On-Site Quality Control

Abstract

Automation and monitoring of modern hydraulic fracturing treatments demand a unique approach incorporating intelligent data acquisition and control equipment. This paper describes how a computerized system was applied to the task. During a treatment, several operations are conducted concurrently. Concentrated gelling agents must be precisely proportioned with various additives to form a base gel. This base gel is then blended with sand, crosslinking agents, and breakers to form the slurry that is pumped into the formation. These operations dictate the metering, measuring, and controlling of many parameters simultaneously over several pieces of mobile equipment. Multiple microprocessor-based control modules are used to perform this task. Each module interfaces with various transducers involved in a particular operation. The use and design of these control modules are outlined, as well as the transmission of information between the modules and the operations control computer. The hardware, software, and ergonomic aspects of the system are discussed. Finally, an additional engineering computer system is outlined, including it link to the central monitor. The presentation of information in a manner to facilitate quality control is discussed. Throughout this paper, emphasis is placed on the use of computer technology to simplify and improve data analysis and quality control.
