Совершенствование метода прогнозирования при многостадийном гидроразрыве пласта юрских отложений на нефтяных месторождениях Западной Сибири

В работе рассматривалась использование технологии бурения горизонтального ствола с применением многостадийного гидравлического разрыва пласта. Проанализирован опыт применения данной технологии на различных месторождениях Томской области, приведенный к равным условиям. Смоделирована адаптированная, при помощи фактических данных, секторная гидродинамическая модель месторождения. Сформулированы рекомендации по выбору ориентации горизонтального участка ствола скважины при помощи полученных результатов расчета модели и экономических показателей.In the paper, the use of horizontal drilling technology with the use of multi-stage hydraulic fracturing was considered. The experience of using this technology in various fields of the Tomsk region, reduced to equal conditions, is analyzed. A sector-specific hydrodynamic model of the field was adapted using actual data. Recommendations are formulated for choosing the orientation of the horizontal section of the wellbore with the help of the results of calculating the model and economic indicators

Oncoplastic breast consortium recommendations for mastectomy and whole breast reconstruction in the setting of post-mastectomy radiation therapy

Aim: Demand for nipple-and skin-sparing mastectomy (NSM/SSM) with immediate breast reconstruction (BR) has increased at the same time as indications for post-mastectomy radiation therapy (PMRT) have broadened. The aim of the Oncoplastic Breast Consortium initiative was to address relevant questions arising with this clinically challenging scenario. Methods: A large global panel of oncologic, oncoplastic and reconstructive breast surgeons, patient advocates and radiation oncologists developed recommendations for clinical practice in an iterative process based on the principles of Delphi methodology. Results: The panel agreed that surgical technique for NSM/SSM should not be formally modified when PMRT is planned with preference for autologous over implant-based BR due to lower risk of long-term complications and support for immediate and delayed-immediate reconstructive approaches. Nevertheless, it was strongly believed that PMRT is not an absolute contraindication for implant-based or other types of BR, but no specific recom-mendations regarding implant positioning, use of mesh or timing were made due to absence of high-quality evidence. The panel endorsed use of patient-reported outcomes in clinical practice. It was acknowledged that the shape and size of reconstructed breasts can hinder radiotherapy planning and attention to details of PMRT techniques is important in determining aesthetic outcomes after immediate BR. Conclusions: The panel endorsed the need for prospective, ideally randomised phase III studies and for surgical and radiation oncology teams to work together for determination of optimal sequencing and techniques for PMRT for each patient in the context of BRPeer reviewe
