The problem of lost circulation occurs almost permanently during drilling operations. When drilling highly permeable, highly fractured, and depleted zones, large drilling fluid losses lead to increased operational expenses. Lost circulation may have several consequences, including fluid inflow, wellbore collapse, formation damage, nonproductive rig time, and environmental issues. In the last century, lost circulation has presented great challenges to the petroleum industry, requiring large capital expenditures and time to address the problem. A particular challenge is depleted reservoirs. As the reserves decline, pore pressure decreases, resulting in weakened hydrocarbon-bearing rocks; nearby or inter-bedded low permeability rocks, however, may maintain their pore pressure. This situation can make the drilling of certain depleted zones extremely difficult. Generally, the fluid density necessary to support the shale above exceeds the fracture resistance of the sands, silts, or carbonates below. Consequently, it is vital to design the drilling fluid to minimize mud invasion into formation and prevent lost circulation, and to provide the possibility of removal at a later stage (completion).To mitigate circulation loss risks, a broad range of treatments and preventive methods using lost circulation material (LCM) have been tried and recommended over the years with varying degrees of success and efficiency. This paper presents an extensive review of the applications of various technologies, both proven and potential, in LCM for sandstone and carbonate depleted reservoirs. It describes the state of the art, advantages, limitations, and suggested specific applications. It also presents recent references of their uses in the petroleum industry and discusses the application and the status of the technologies.For sandstone, the materials discussed focus on LCM in the form of flakes, granules, fibers, blends of these materials, particulate materials, polyglycolic acid (PGA) and polylactic acid (PLA) materials, as well as nanoparticles (NP) and nanocomposites. For carbonate formations, the scope includes conventional LCM, such as cement plugs, settable plugs, polyurethane grouting and other new technologies, such as gels, viscoelastic surfactant gels (VES), and crosslinked gels.This review compiles crucial information necessary to design and formulate the fluid using LCM for the depleted reservoir challenges.

Efficient Adaptive Test Method for Textile Development Length in TRC

Natural resources can be conserved if we carefully maintain the building stock and indeed extend the useful economic life of buildings. One way to achieve this is to enhance load-bearing structures by repair, restoration, or strengthening. Such upgrading often involves applying a strengthening to existing concrete elements. Over the past decade, textile-reinforced concrete (TRC), encompassing a combination of fine-grained concrete and noncorrosive multiaxial textile fabrics, has emerged as a promising novel alternative for strengthening of conventional steel-reinforced concrete (RC) structures, offering enhanced load-bearing capacity with minimal weight and stiffness change. Although TRC has been extensively researched during the last two decades, the formalization of experimental methods and design standards is still in progress. Attempts to design for good load transfer are often hindered by lack of knowledge regarding bond behaviour. For instance, there are neither standard recommendations nor proofs regarding the required development length of textile fibres in TRC for practical applications up to now. e aim of this work was to provide a test specification, which gives a direct result for the development length (required for the anchorage of a reinforcement, also referred to as "anchorage length") of textile reinforcements in fine-grained concrete-quickly and easily. e aim of this paper was to present the test specification developed in a way that it is useful for the future work of other researchers as well as for construction engineers. Some selected experimental investigations with different textile reinforcements and different bonding properties were performed with the aim of showing the applicability of the proposed adaptive test specification. e results of these tests indicated that conventional AR glass and carbon fabrics without coating required large anchoring lengths. e tests further showed that an additional application of different kinds of coating to textile fabrics greatly increased the reinforcement's resistance to pullout. is is of special interest for carbon fibres, which have a substantially higher strength than AR glass fibres and different bond behaviour; that is, carbon fibres have, by nature, larger development lengths.
