In the past, serial drilling operations have been employed for the conventional well-architecture construction process. In this paper, new technological advancements from initial design planning to execution processes will be discussed. These advancements produce a "step-change" well architecture with a uniform well diameter and fullbore production delivery conduit called a monowell. From the well-construction processes to the "end" product, efficiency is driven in the technologies and processes described. Technical improvements in mechanical and chemical solutions can help achieve a well architecture with a uniform diameter in reduced serial operations. Technological advancements in the areas of composite technology and real-time downhole monitoring can enhance deployment efficiency compared to conventional methods. The efficiency processes yield a well architecture with more efficient reservoir penetration and oil-production delivery by:Reducing formation/reservoir evaluation time and well placement through better methodsIncreasing penetration rateReducing the volume of drill cuttings and the oil content contained on the cuttingsReducing fluid requirements (i.e. drilling fluids and cements)Reducing casing size and the number of casing strings requiredReducing overall rig timeReducing overall flat timeImproving well productivityReducing required horsepower and rig size The unique design and planning features of the monowell are discussed, including reservoir focus, geomechanics, and design requirements of drilling systems, formation evaluation equipment, fluid systems, and wellbore hardware. Multiple "uniform diameter" well-construction execution methods, including multiple deployment methods, are discussed. Together, the well-architecture change and execution-process changes result in a monowell with improved well construction design, execution, and production efficiencies. The monowell provides a significant industry step change in reducing cost per barrel of oil equivalent through improved efficiencies through a multitude of technologies. Factors to Consider during the Monowell Well-Construction Process A higher level of engineering and technological precision is needed to deliver the monowell compared to traditional well-construction processes. When a monowell is drilled, increased precision is required in the following areas: Upper BoreholeClear understanding of the formations to be drilled and being drilledBorehole stabilityDrilling hydraulicsEffective management of equivalent circulating density (ECD)Borehole qualityMethod of strengthening the borehole (borehole management)Well-life integrityReliability and run life of the bottomhole assembly (BHA) componentsLonger cementing and casing execution intervalsBorehole structural support Reservoir SectionCompletion, beginning with drilling of the reservoir barrierBorehole qualityBorehole stability across the reservoirReservoir evaluationReservoir productivityFormation damage minimization
Kenyataan lapangan membuktikan bahwa terjadinya kesenjangan antara tujuan khusus pengajaran dengan apa yang dikerjakan guru Pendidikan jasmani di lapangan menyebabkan prestasi akademik tidak dinyatakan secara jelas. Penekanan evaluasi proses belajar mengajar di sekolah adalah pada evaluasi formatif dan sumatif, tanpa disadari bahwa berbagai penyimpangan dan kekurangan sering dialami guru pendidikan jasmani dalam merencanakan program pengajaran senam dan mentransformasikan ke dalam proses belakar mengajar. Pembuatan satuan pengajaran hanya menitikberatkan pada input, proses, dan produk untuk memperbaiki hasil belajar mengajar melalui pengajaran remedial dan belajar tuntas, tai kenyataannya prestasi akademik tidak dapat dinyatakan secara jelas (intangibel). Di samping itu, satuan pengajaran di sekolah seolah-olah dianggap baku, walaupun tiap sekolah berbeda dan dilaksanakan hanya sebagai pertanggungjawaban administrasi tanpa dievaluasi.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
