The cement sheath, serving as the primary element of well barriers, plays a crucial role in maintaining zonal isolation, protecting the casing from corrosion, and providing mechanical support. As the petroleum industry shifts from conventional to deep unconventional resources, the service environment for cement sheaths has become increasingly complex. High temperatures, high pressures, cyclic loading, and thermal stresses in downhole conditions have significantly increased the risk of cement sheath failure. A growing trend toward theoretical analysis of stress distribution, failure modes, and control mechanisms within the casing-cement sheath-formation system is evident. This paper comprehensively reviews theoretical research on cement sheath integrity from four key perspectives: (1) the concept of cement sheath integrity failure, (2) cement sheath constitutive models, (3) analytical models of the cement sheath-casing-formation system, and (4) numerical simulations of the cement sheath-casing-formation system. Through these discussions, this review provides profound insights into cement sheath integrity failure and offers valuable guidance for future research and practices.

“…В работе S.Taoutaou и др. [30] описывается успешное полевое испытание самовосстанавливающейся цементной системы в качестве вторичного барьера для повторной зональной изоляции на газовом месторождении в отложениях Хуфф на Ближнем Востоке. На скважине периодически возникали проблемы с наличием постоянного давления в обсадной колонне из-за скважинных напряжений и других факторов.…”

“…Самовосстанавливающийся цементный композит, используемый в качестве вторичного барьера для восстановления зональной изоляции (в случае утечки газа в результате разрушения первичного гибкого и расширяющегося цемента), основывался на технологии активации углеводородами (в данном случае газом) с механизмом перекрытия путей утечек путем набухания. Таким образом, самовосстанавливающаяся суспензия была разработана для конкретных условий месторождения (газ на 90% состоит из метана) и включала в свой состав пеногаситель для уменьшения пенообразования во время смешивания, диспергатор для понижения трения и контроля реологии, агент контроля водоотдачи и замедлитель схватывания [30].…”

“…Цемент был равномерно распределен по обсадной колонне за счет хорошей централизации, мероприятий по проектированию состав суспензии и хорошего удаления бурового раствора. В целом, использование самовосстанавливающегося цементного композита в качестве вторичного барьера оказалось очень эффективным и рентабельным мероприятием для обеспечения долгосрочной зональной изоляции, а по результатам проведенного гидравлического тестирования утечек не наблюдалось [30].…”

The main purpose of cementing oil and gas wells is zonal isolation of the formations exposed by the wellbore. During the entire life of the well, there should be no uncontrolled hydraulic communication between the developed formations and the surface, regardless of the composition and type of fluid (water, oil or gas). During the operation of the well, in addition to constant static ones, the casing and cement stone also experience various dynamic loads. The article presents an up-to-date review of experimental studies on the modification of grouting compositions and cement composites capable of autonomous selfhealing due to the introduction of various additives and nanomaterials. Such modification technologies significantly increase the tightness and resistance of cement to the effects of dynamic loads, the integrity of the cement stone. As a replacement for traditional cement materials, the authors propose the creation of grouting compositions with controlled physical and mechanical properties and the possibility of their re-liquefaction under the influence of temperature on the basis of bitumen or bitumen composites. Keywords: well plugging and abandoning; self-healing materials; autonomous self-healing; casing durability; impermeability of the cement stone; self-healing cement; bitumen and bitumen composites.

Areal footprints of current and future hydraulically fractured oil and gas reservoirs and potential CO2 geological‐sequestration intervals often overlap in sedimentary basins. Significant vertical separations between prospective subsurface volumes, however, will limit their interaction, particularly if the carbon‐storage site is deeper than the hydrocarbon resource. Recent intense development of shale resources translates into a reduced need for sequestration capacity. It has also resulted in technological innovations directly transferable to the carbon‐storage industry, in particular progress on well completion, such as new approaches to cementing, more mature horizontal drilling methods, and development of field‐treatment techniques for saline water. In addition, knowledge collected by operators on stratigraphy and faults – for example, using 3D seismic – and on abandoned wells is directly useful in reducing risk in future carbon‐storage projects. Both industries can benefit from development of regional transmission pipelines, pipeline rights‐of‐way, and a trained workforce. From a regulatory standpoint, hydraulic fracturing of shale and tight formations is not considered injection. Under the US UIC program, because hydraulically fractured wells fall under the production category, they do not follow the same set of rules for protecting water resources as oil and gas industry disposal wells do (UIC Class II). Both subsurface uses share some risk elements, however. Environmental risks result mostly from abandoned wells and faults, poorly characterized for carbon storage, and from defective well completions and surface spills during oil and gas production. Operators of both fields are also concerned about disposal of large fluid volumes possibly generating seismic events. © 2012 Society of Chemical Industry and John Wiley & Sons, Ltd
