“…The oil and gas industry has witnessed an upsurge in measures aimed at increasing the oil recovery from green reservoirs [2][3][4]. As part of these initiatives, waterflooding has been widely adopted as the cheapest form of recovery [5][6][7][8][9][10]. However, different factors affect the overall performance of this method [11][12][13], including the structural setup of the reservoir and well type [14,15].…”

Recovery efficiency is a key factor in decision-making in oil and gas projects. Although structural setup and well type considerably influence waterflood recovery, few studies have explored the performance of highly deviated wells during the waterflooding of complex shallow reservoirs. Here, we applied numerical simulations to investigate the performance of vertical, horizontal, multilateral, and highly deviated wells during waterflooding of complex shallow reservoirs using the J1 Oilfield as a case study. Recovery efficiencies of 31%, 33%, 31%, and 26% could be achieved for vertical, horizontal, multilateral, and highly deviated wells, respectively. The gas production rate was 39% higher in the vertical wells than in the other types. Highly deviated wells yielded the highest water-cut (80%) over a short period. Highly deviated wells delivered the least production, and, despite branching laterals, multilateral wells were also not the most productive. Our results provide insights into the performance of different well types during the waterflooding of green heterogeneous non-communicating reservoirs and present an example of the successful practical application of waterflooding as an initial recovery mechanism when oil is near the bubble point. This study indicated that multilateral wells are not a panacea in reservoir development. Highly deviated wells are the ideal choice for the shallow, heterogeneous non-communicating reservoirs when economic and environmental impact are considered in decision-making. Well design should be a case-by-case study considering reservoir characteristics, economics, and environment impact.

“…There are several methods for understanding the quality of connection between injectors and producers of a field, including tracers, traditional reservoir simulators and datadriven approaches (Moghadam et al 2011;Rong et al 2016;Suleymanov et al 2016;Salehian and Çınar 2019). A datadriven approach uses the injection and production data of a field in order to find the quality of connection between the wells.…”

Waterflooding is among the most common oil recovery methods which is implemented in the most of oil-producing countries. The goal of a waterflooding operation is pushing the low-pressure remained oil of reservoir toward the producer wells to enhance the oil recovery factor. One of the important objects of a waterflooding operation management is understanding the quality of connection between the injectors and the producers of the reservoir. Capacitance resistance model (CRM) is a data-driven method which can estimate the production rate of each producer and the connectivity factor between each pair of wells, by history matching of the injection and production data. The estimated connectivity factor can be used for understanding the quality of connection between the wells. In the waterflooding operation, the injected water always has the potential of causing formation damage by invasion of foreign particles deep bed filtration (DBF), mobilization of indigenous particles (fines migration), scale formation, etc. The formation damage can weaken the quality of connection (connectivity factor), between the injectors and producers of the field, increasing the skin of injection well. In this paper, DBF is used for creation of formation damage in synthetic reservoir models. Then, it has been tried to find the existence and amount of formation damage by evaluating the connectivity factor of CRM. Finally, the results of that have been used for prediction of skin variation in a real case by using the connectivity factor of CRM.

Актуальность исследования обусловлена необходимостью обобщения накопленного опыта и информации по применению общепринятых методов анализа эффективности системы поддержания пластового давления, выявления достоинств и недостатков каждого отдельного метода и формирования рекомендаций по упрощению процесса проведения анализа эффективности при одновременном увеличении глубины и качества анализа, в перспективе обеспечивающих сокращение потерь добычи нефти. Целью исследования является формирование рекомендаций по совершенствованию процесса анализа эффективности системы заводнения нефтяных пластов на месторождениях, находящихся на поздних стадиях разработки. Объект: южная лицензионная территория Приобского месторождения (Ханты-Мансийский автономный округ). Методы: сравнительный анализ существующих методов оценки эффективности систем заводнения нефтяных пластов, выявление достоинств и недостатков, формирование комплексного подхода к применению методов анализа эффективности системы заводнения, оценка перспективности применения результатов исследования. Результаты. Рассмотрена методика оптимизации процесса анализа эффективности системы заводнения нефтяных месторождений путём разделения их на более мелкие гидродинамически замкнутые участки пласта – блоки (ячейки заводнения). Для повышения качества проводимого анализа предложен переход от реактивного подхода диагностики потерь к проактивному подходу, позволяющему предсказать и предотвратить снижение добычи нефти. На основании тенденции к укрупнению участков пласта, подлежащих анализу, по сравнению с традиционными методами анализа, и внедрения проактивного подхода предложен алгоритм повышения эффективности управления базовой добычей – проактивный блочно-факторный анализ. Рассмотрена перспективность применения результатов блочно-факторного анализа на примере одного из блоков Приобского месторождения (Ханты-Мансийский автономный округ). Возможно применение представленного алгоритма анализа для схожих геолого-физических условий других пластов с целью адаптации данной технологии на территории других месторождений.
