Technical, Economic And Environmental Considerations For Selecting Next Generation Hydraulic Fracturing Equipment Technology

SPE – 210215


Recently, the North America Oil and Gas industry has seen a rapid increase in the adoption of new hydraulic fracturing technologies such as dual-fuel diesel engine, electric system powered by gas turbine or engine on-site and turbine direct drive technology, to reduce emissions and operating costs. The objective of this paper is to provide a detailed analysis of economic, environmental, and technical considerations when selecting the next generation hydraulic fracturing equipment platform.

A Cationic Friction Reducer Fully Compatible With Produced Water



The high intensity of hydraulic fracturing in unconventional reservoir has resulted in dramatic increase in water consumption. The reuse of produced water has been driven by both the environmental and economic benefits. The performance of conventional anionic friction reducers is usually affected by the total dissolved solid (TDS) in the water source. We present here a cationic friction reducer which is fully compatible with most of produced water based on results from the lab and field.

Perfecting Operational Execution: The Journey To High Reliability In The Oilfield



High Reliability Organizations (HROs) are organizations with systems that maintain exceptionally low failure rates while operating in environments where the nature of the risk and complexity of serious incidents would be anticipated. The aim of this paper is to illustrate how the principles, concepts, and processes of HROs, including Crew Resource Management (CRM), can optimize operational execution.

Far-Field Diversion System Designed For Slickwater Fracturing



Fracture geometry control and increased fracture complexity have been recognized to be critical factors in optimizing unconventional well completion design. A major challenge of far-field diversion in slickwater fracturing is ensuring transport of material to the fracture tip or secondary fracture in a low-viscosity fluid. This paper will present an innovative far-field diverter system for fracturing with low-viscosity fluids composed of an engineered mixture of unique ultra-lightweight proppant and degradable material.

Can Friction Reducers Transport Sand During Fracturing Treatment?



This paper provides a comprehensive study of friction reducers as linear or crosslinked guar system replacement for transporting proppant. An in-depth understanding of the key factors controlling proppant carrying capability of FRs is critical to improved fracturing fluid design.

Gelled Isolation Fluid Makes Refracturing Well Feasible



A gelled fluid offers the benefits of being both temporary and easily cleaned up after the treatment. The objective in this application was to use a low cost gelled fluid to fully isolate existing perforations along a lateral to stimulate new zones. The novelty of this work included the application of using a gelled fluid in conjunction with a sliding sleeve system.
