ABSTRACT The well construction process has recently made a considerable step forward enabling drilling of challenging onshore and offshore wells due to implementation of new technologies. This refers to wells featuring complex paths, high temperatures and high pressures, mud losses, fluid and gas kicks. Mitigation of drilling hazards is generally time consuming and costly, to say nothing of possible environmental damages. Incorrect or late event detection can result in costly downtime. For instance, inadequate mud weighting to avoid a kick or a blowout can result in increased differential pressure and lost circulation as the fracture gradient is exceeded. This, in its turn, will induce kick and loss cycles and additional costs to restore operations. And this will therefore entail increased drilling costs. Consequences of such actions can include formation damages, decrease of initial production rates or local formation damages with a need for sidetracking. This paper covers state-of-the-art technologies enabling to prevent various drilling hazards including managed pressure drilling, continuous circulation drilling and drilling-with-casing or liner. Managed pressure drilling technologies help mitigate well construction risks, improve drilling efficiency and make previously undrillable wells drillable by maintaining an optimal pressure differential and virtually managing inflows. Application of closed-loop control systems both on onshore and offshore rigs creates a range of opportunities to improve the drilling process for higher personnel safety, exclude risks for the environment and equipment and at the same time improve the well economics. Continuous circulation drilling during the whole “running-drilling-makeup-drilling-pulling” cycle along with the managed pressure drilling technology enables drilling in “narrow drilling windows” but does not feature a closed-loop system, which limits its equivalent circulation density control capabilities to mud flow rate only. The drilling-with-casing technology is considered not only as a revolutionary means to mitigate hazards such as tight spots preventing further casing running or water kicks, but also as a means for well design optimization. Combined drilling-with-liner and managed pressure drilling technologies enable to solve the problems of optimal reservoir exposure and casing. Application of pressure management techniques during well cementing, in its turn, considerably improves the casing quality and reliability in challenging wells thus providing long-term economic benefits during well operation. The DwC/DwL technology can use both retrievable and nonretrievable assemblies, which enables to use downhole motors with M/LWD systems. Torque can be transferred to casing by various devices including OverDrive system. Many of the above technological solutions have been used in Russia, though as pilot projects, and have good “track records” worldwide, especially at offshore fields.

ТЕЗИСЫ ДОКЛАДА

В докладе будет представлен новый выпуск Прогноза развития энергетики мира и России до 2040 г. Предыдущие выпуски показали высокую потребность страны в наличии собственного видения раз-вития мировой энергетики. Материалы «Прогнозов» широко обсуждаются в России и за рубежом, активно используются в государственных и корпоративных стратегических документах, в научных и прикладных исследованиях. Новый выпуск представляет видение развития ситуации на мировых энергетических рынках и в России на период до 2040 г. В новом Прогнозе-2016:

• анализ последних изменений, трансформирующих устоявшиеся тренды в мировой экономике и энер-гетике, и оценка того, как будет развиваться мир в ближайшие 25 лет;

• результаты прогнозирования конъюнктуры рынков углеводородов на основе усовершенствованного модельного комплекса, позволяющего детально рассматривать мировые рынки нефти, газа и угля;

• детальный анализ изменения перспектив российской экономики и энергетики под влиянием новых трендов: насколько чувствительны будут последствия этих глобальных изменений для России?
