Abstract:

The oil and gas industry plays a vast and vital role in our society. Despite the numerous benefits of the production of crude oil, its activities pose a lot of dangers to the environment and living organisms because it generates a huge volume of solid and liquid wastes, thus, these wastes require treatment before disposal. The major drilling wastes are drilling muds, drilling cuttings, and obnoxious gas emissions. Parameters that should be considered during the disposal of decontaminated drilling muds and drill cuttings are heavy metals. These wastes are introduced into the environment through

A great number of studies are dedicated to the definition of heat conductivity of drilling muds and cement slurries. It should be noted that existing works on the specification of heat conductivity of the drilling mud are based on either experimental or theoretical studies in which well conditions are reflected incompletely. Considering all above-mentioned aspects, the practical interest consists in the definition of thermal conductivity of drilling muds and cement slurries in well drilling on the basis of the data obtained at the wellhead during unsteady processes execution.

Each year, the oil industry generates millions of barrels of wastes that need to be properly managed. For many years, most oil field wastes were disposed of at a significant cost. However, over the past decade, the industry has developed many processes and technologies to minimize the generation of wastes and to more safely and economically dispose of the waste that is generated. Many companies follow a three-tiered waste management approach. First, companies try to minimize waste generation when possible. Next, they try to find ways to reuse or recycle the wastes that are generated. Finally,

The chemical agents, materials and drilling mud types developed on them and applied in the drilling of oil and gas wells significantly affect the technical-economic parameters of well construction. Moreover, in the time of the innovative technologies implemented in the context of the drilling mud, the consideration of the environmental aspects is crucially important and defines the most significant research areas as well. Therefore, the minimization of the impact of the drilling mud types and the particles of subsurface rocks transported from the depth on the environment is of no small interes

Abstract:

Hydrocarbon-based solutions (HCBS) today are capable ofperforming tasks that water-based muds cannot do. First of all — theability to keep the well walls at a lower density, their insensitivity to clayand salt deposits, the similar nature of the hydrocarbon base and reservoirfluids. These advantages make it possible to use HCBS in the constructionof wells characterized by intensive caving, with high zenithangles and extended horizontal sections. HCBS is successfully appliedat the fields located beyond the Arctic Circle when opening, for example,Devonian deposits. But in addition to the indispu

Abstract:

Fishbone Drilling (FbD) consists of drilling several micro-holes in different directions from the main vertical or deviated wellbore. Similar to multilateral micro-hole drilling, FbD may be used to enhance hydrocarbon production in naturally fractured formations or in refracturing operations by interconnecting the existing natural fractures. When combined with underbalanced drilling using a coiled tubing rig, FbD enhances the production further by easing the natural flow of the hydrocarbon from the reservoir to the wellbore. The design aspects of the Fishbones include determining the number, l

Unconventional geothermal resource development can contribute to increase power generation from renewable energy sources in countries without conventional hydrothermal reservoirs, which are usually associated with magmatic activity and extensional faulting, as well as to expand the generation in those regions where conventional resources are already used. Three recent drilling experiences focused on the characterization of unconventional resources are described and compared: the Campi Flegrei Deep Drilling Project (CFDDP) in Italy, the United Downs Deep Geothermal Power (UDDGP) project in the

The introduction of energy sanctions differed from other trade restrictions imposed on other Russian sectors of the economy or individual goods and services due to the fundamental feature of oil as an easily traded and relatively interchangeable commodity. The results of the study showed that the impact of sanctions on the Russian economy was mitigated by redirecting oil to other countries that, according to their national law, are not obliged to comply with sanctions. Relatively inelastic short-term demand for oil and natural gas at a price led to Russia’s revenues from the sale of energy res
