Horizontal Sucker Rod Pumping Wells – Novel Unconventional Dyna Card Signatures Interpretation for Pump & Rod Run-life Optimisation

Abstract

Abstract This paper presents a comprehensive and pioneering analysis, exploring the hitherto uncharted terrain of newly discovered dyna-card signatures and learnings associated with their analysis. These signatures, emblematic of an intricate interplay between high-deviation, azimuth, Dog-Leg Severity, and rod-guide application in horizontal-well configurations, constitute a novel dimension in the pursuit of optimizing pump and sucker-rod run-life. The emergence of these distinct dyna-card signatures unveils a paradigm shift, transcending the boundaries of convention by redefining the landscape of artificial lift systems. These signatures, while intricately linked to the complex conditions of horizontal-well operations, are conspicuously absent from the annals of existing literature. So, this paper will fill the gaps of theory & literature. By methodically delving into the core of these unconventional signatures, this paper embarks on an intellectual journey that transcends the known boundaries of understanding. This journey traverses through a comprehensive examination of not only the novel dyna-card signatures but also a spectrum of both rare and common dyna-card signatures. The outcome of this analytical odyssey is a revelation of strategies that cast light on the path to bolstering the longevity and efficacy of rod-string and pump performance. These novel & unconventional dyna-card signatures are connected with the challenges posed by elevated wear rates of rod-couplings and rod-guides, particularly where they interface with the tubing-wall, the paper introduces an arsenal of specialized rod-string designs to overcome these problems identified by the specialized dyna-card signatures. These designs, forged at the intersection of innovation and necessity, stand as a testament to the commitment to harnessing newfound knowledge in a practical manner.
