Objective/Scope Optimizing production across unconventional assets requires rapid identification of well performance anomalies, efficient artificial lift optimization, and scalable evaluation of intervention opportunities such as acid jobs and lift-system transitions. Traditional surveillance workflows struggle to keep pace with high well counts, changing lift designs, and evolving reservoir...

Oil and gas operators face growing expectations to improve operational performance, manage risk, and demonstrate responsible emissions management. Finalized New Source Performance Standards (NSPS) rules for OOOOa and OOOOb sites enable a more efficient, data-driven approach to Leak Detection and Repair (LDAR) compliance. Under these regulations, operators can use traditional Optical Gas Imaging...

1. OBJECTIVES/SCOPE Modern wellhead inspection systems depend largely on operators interpreting electromagnetic signal graphs displayed on their laptops. Because this task demands both extensive training and unwavering focus, results can vary or be inconsistent due to the subjective nature of human judgment. This work seeks to present an approach based on intelligent algorithms to reduce such...

Beneath the Surface: Data-Driven Analysis Illuminates Well Performance Artificial lift decisions directly influence production sustainability and operating costs across thousands of unconventional wells. Yet despite the volume of data surrounding rod-lift systems, the information that should guide performance improvement often remains scattered across departments and disconnected from the...

As companies move to lower their operating and maintenance costs, gas lift use has seen a dramatic increase in unconventional production patterns in the Permian Basin.1 Due to the corrosivity of acid gasses and the corrosive nature of produced water in these wells, asset protection is crucial to provide long-term production and minimize costly workovers. In this study, we will review a gas lift...

To address the escalating demands for decarbonization within the petroleum industry, a pioneering technology known as in-situ hydrogen (H2) production via electromagnetic-assisted catalytic heating has recently been proposed for extracting clean H2 directly from petroleum reservoirs. This study explores H2 generation from hydrocarbon/water reactions in the presence of natural rock powders under...

The phenomenon of liquid loading is a dominant limitation in developed gas fields globally. Apparently, all gas wells will experience this depleting process in the subsequent phases of their production. The primary problem in dealing with liquid loading is the issue of forecasting its occurrence and accurately determining its onset. This paper is focused on developing an improved model for...

Vulnerability of remote monitoring and control systems in the Oil and Gas industries By George Tyson and David Allen, Oiltek Systems LLC The Modern oil and gas industry extensively uses systems to remotely monitor and control operations throughout the process. Supervisory control and data acquisition (SCADA) systems have had wide acceptance and used for years. Many SCADA systems use the Modbus...

Catastrophic accidents in offshore drilling operations have greatly endangered human lives, environment and capital assets. Although risks in offshore oil and gas operations cannot be completely eliminated, a substantial amount of risks can be minimized through preventive and mitigative measures. A key aspect of the offshore drilling risk is the reliability of drilling systems. According to the...

The perceived impact of chlorine dioxide (ClO2) on the corrosion of steel used in the oil patch has been a controversial issue for many years.   Although a few studies on this issue have been published, those results have been contradictory. As concerns surrounding this issue continue to be raised, a systematic study has been undertaken to understand the corrosive effects of ClO2 towards steel in...
