Technology Focus: Production and Facilities (December 2022)

Abstract

The COVID-19 pandemic has caused unprecedented circumstances affecting production and facilities. Restrictions in mobility between sites and reduction in manpower challenged the business continuity of several operations. This accelerated the development and implementation of various technological solutions. We can see many examples in the works submitted this year: drone surveillance, inspection robots, digital twins, and automated systems. The digitalization tendency brought by the fourth industrial revolution continues to be the dominant topic of the works submitted. Approximately 28% were on simulation and modeling, of which one-third used machine learning. A total of 9% addressed intelligent management systems, 5% robotics and drones, 3% 3D printing, and 1.5% digital twins and augmented reality. The main topics addressed were inspection and maintenance (20%), flow assurance (7%), corrosion (6%), drilling (6%), nonmetallic materials (3%), and debottlenecking (2%). A few papers were on clean energy subjects, such as hydrogen energy and wind turbines (2%). I would like to highlight the following works as promising technological developments for production and facilities: innovative measurement techniques, such as the development of a new adjustable cone meter that adapts automatically to flow conditions of wet and dry gas (paper SPE 207505); improvements to drilling safety, such as the design of a new casing connector that significantly reduces rig time and health, safety, and environmental exposure risks (paper OTC 31075); new developments in piping inspection, such as the combination of direct-response spectroscopy with microwave for inspection of hard-to-inspect piping with coatings and overwraps (paper IPTC 21799); and a very interesting study of triangular vs. circular cross-sectional pipes, which shows that triangular pipes and elbows have significant less erosion, better heat transfer properties, and reduced slug frequencies for multiphase flow (paper SPE 208101). In the matter of optimizing production, debottlenecking continues to be a challenge. Whether it is for increase of production needs or for handling greater water cuts from aging wells, new technological solutions are arising to make production facilities increasingly efficient. Paper IPTC 22365 discusses dual-frequency AC/DC desalting technology. It shows a reduction in costs and energy requirements while achieving superior basic sediment and water removal. One of the topics becoming more relevant is the reduction of CO2 emissions. At least 5% of the abstracts I reviewed addressed lowering CO2 emissions as their main topic. Energy harvesting is an economically interesting way to reduce emissions because the energy consumption of the facility is reduced. The study shown in paper OTC 31724 describes energy harvesting from hydraulic pressure drops as an example of the circular economy applied to oil-production facilities. In this study, the energy and costs savings were evaluated at different pressure-drop points of a gas/oil separation plant. Paper SPE 207096 uses pinch analysis to perform a detailed heat-exchange-network retrofitting study of a crude distillation unit, predicting 8% of energy savings. I sincerely hope that we can see more developments in this area in coming years. Recommended additional reading at OnePetro: www.onepetro.org.
