First Successful Fishbone Stimulation Completion in Onshore Oil Field in the United Arab Emirates.

Abstract

Fishbone Stimulation Technology was developed to increase the well productivity from the tight reservoir for maximum hydrocarbon recovery. Additionally, this technology was implemented in a thin reservoir where conventional stimulation techniques have not been effective and very risky for more aggressive stimulation technique such as hydraulic fracturing. The application of Fishbone Stimulation Technology was the first time experience representing a massive uncertainity. Thus, a multidisplinary team was estasblished, including members of different departments of the operator and contractors, to design the operational procedures, conduct risk assessment, contingency plans, technical requirements and technical limitations. this first implementation of the fishbone stimulation in ADNOC Onshore served as the benchmark and reference for other fishbone candidate wells in ADNOC Onshore and other ADNOC subsidiaries. The deployment of the equipment and the production results were a complete success overcoming the risks and previously mentioned uncertainities, closing some gaps from previous partial effective applications in other companies. The Fishbone stimulation technology will help to increase the well productivity via below mechanism in a well that is too risky to be hydraulically fractured and beyond the coiled tubing reach: Extension of the needles to connect natural fractures and vertical layers (for reservoir with poor Kv/Kh) Increase reservoir contact Sweep Efficiency of the reservoir

A Comprehensive Review of Fishbone Well Applications in Conventional and Renewable Energy Systems in the Path towards Net Zero

“…Several case studies have demonstrated the effectiveness of fishbone well designs in various geological settings and conditions, achieving productivity increases and successful stimulation of reservoirs [24][25][26][27][28][29][30]. These studies have also discussed drilling equipment, tools, and methods used for fishbone well drilling, such as the bottom hole assembly (BHA) consisting of a positive displacement motor (PDM), bend-sub, PDC bit, rotary steerable system (RSS), and logging while drilling (LWD) tools.…”

Design and Performance Analysis of Dry Gas Fishbone Wells for Lower Carbon Footprint

“…Four additional case studies from Russia have been documented in the literature, including sandstone formations in the Vostochno-Messoyakskoye onshore field [17], low permeable formations in the East Messoyakha field [18], the Vankor oilfield in Krasnoyarsk, Eastern Siberia [19], and the Srednebotuobinskoye oil and gas condensate field in Eastern Siberia [20]. In the UAE, successful FbD case studies have been reported in naturally fractured reservoirs [21,22], and an innovative Fishbone infill well was applied in the Canadian oil sands play [23]. Research into applications of Fishbone well configurations in areas such as geothermal drilling, enhanced oil recovery, steam-assisted gravity drainage, and underground saltwater disposal are ongoing [24,25].…”
