The Challenges and Lessons Learned from the Unanticipated Long Run Well Unloading Campaign in T Field, Malaysia

This paper presents overall challenges and experiences that the team were facing during offline well unloading campaign recently. On paper, offline well unloading is more favorable as an option to minimize environmental impact, economize rig days and reuse produced clean-up oil. This practice is not new. The implementation of this practice to a 40-year-old brown fields led to successfully bring adopted for two drilling campaign. The well unloading to the existing facilities requires substantial strategies to be adapted and possibilities to handle drilling fluids and solid/debris are extensively discussed within multi disciplinary team whereby risk evaluation was conducted ensure the good progress of this operation. The assurance part to handle production of solid/debris along with produced fluid to surface within 12 hours operation with the assitace from Hook-Up and Commissioning (HUC) work barge initially and resumed later by daily trip via boat to offshore site will be discussed in this paper. Almost 90% of this activity is carried out with crews mobilized with 45-minute boat trip from Bintulu to site, highly depended on weather condition. This paper also will share the major challenges that resisted the good progress of unloading for four wells such as limitation associated setting of the surface Hi Lo Pilot safety switch that cannot handle the transient flow condition, huge pressure drop exerted by the inline surface strainer that temporarily installed to filter any solid production, unintentional jammed close of Tubing Retrieveable Surface Controlled Subsurface Safety Valve (TRSCSSV), unanticipated low performance of gas lift compressor that restricted the wells to continuously flow to the test separator and temporary high H2S gas release throughout the well unloading operation. Due to daily tripping, the crew left with constrained time of 4 - 5 effective hours only per day in attempts to kick off and flow the wells. On paper, offline well unloading indeed offered 70% cost saving compared to clean up with rig. However, in actual it resulted to increase 3 times in well cost and delay in achieving first production target which was 6 months later from the plan due to unanticipated causes that prolong the unloading activities.

Real Driving Range in Electric Vehicles: Influence on Fuel Consumption and Carbon Emissions

This paper is focused on the determination of real driving ranges for electric vehicles (EV’s) and how it influences fuel consumption and carbon emissions. A precise method to evaluate the driving range of an EV can establish the correct reduction in GEI amount, mainly CO and CO2, ejected to the environment. The comparison of the daily driving range between an internal combustion engine (ICE) vehicle and an EV provides a useful tool for determining actual fuel saved during a daily trip and a method to compute carbon emissions saved depending on the type of ICE vehicle. Real driving range has been estimated on the basis of a daily trip consisting of five different segments, acceleration, deceleration, constant speed, ascent and descent, which reproduce the different types of driving. The modelling has been developed for urban routes since they are the most common and the most polluted environment where the use of electric vehicles is applied. The effects of types of driving have been taken into account for the calculation of the driving range by considering three main types of driving: aggressive, normal and moderate. The types of vehicle in terms of shape and size as well as dynamic conditions and the types of roads have also been considered for the determination of the driving range. Specific software has been developed to predict electric vehicle range under real driving conditions as a function of the characteristic parameters of a daily trip.

METHODS OF IMPLEMENTATION OF AN ALPINE SKIING SCHOOL

Nowadays, various programs are used in ski schools to teach beginners. All programs have the same goal, and that is to teach beginners specific body movements with which they will be able to manage their skis. Three programs are most commonly used in alpine skiing schools. According to one program, ski beginners are taught the basics of alpine skiing exclusively with elements of parallel skiing techniques. In the second program, ski beginners acquire knowledge using elements of snowplough and parallel ski technique. The third alpine skiing learning program combines these two methods. In addition to the program, in practice there are two approaches to learning alpine skiing. The first method involves a daily trip to a ski slope or a nearby winter tourist centre, where the skiing technique is adopted and beginners return to the place of residence the same day. The second way consists of an organized, usually seven-day, winter trip, during which the basics of alpine skiing are learned every day during the stay in the ski-resort. Regardless of the learning programs used, the safety of skiers is a priority in every alpine skiing school. Therefore, it is advisable for all beginner skiers to get involved in an alpine skiing school, as this is the best way to prevent injuries.

Optimal Driving Range for Battery Electric Vehicles Based on Modeling Users’ Driving and Charging Behavior

This paper proposes a simulation approach for the optimal driving range of battery electric vehicles (BEVs) by modeling the driving and charging behavior. The driving and charging patterns of BEV users are characterized by reconstructing the daily travel chain based on the practical data collected from Shanghai, China. Meanwhile, interdependent behavioral variables for daily trips and each trip are defined in the daily trip chain. To meet the goal of the fitness of driving range, a stochastic simulation framework is established by the Monte Carlo method. Finally, with consideration of user heterogeneity, the optimal driving range under different charging scenarios is analyzed. The findings include the following. (1) The daily trip chain can be reconstructed through the behavioral variables for daily trips and each trip, and there is a correlation between the variables examined by the copula function. (2) Users with different daily travel demand have a different optimal driving range. When choosing a BEV, users are recommended to consider that the daily vehicle kilometers traveled are less than 34% of the battery driving range. (3) Increasing the charging opportunity and charging power is more beneficial to drivers who are characterized by high daily travel demand. (4) On the premise of meeting travel demand, the beneficial effects of increased fast-charging power will gradually decline.

Spatial behaviour and healthy aging. A GPS-ased study of the older residents in Shanghai

The spatial behavior of elderlies is essentially the result of interactions between people and the environment. In order to explore a demand-responsive spatial intervention through new types of data from the perspective of urban planning, this study attempts to identify the differentiated trip features within the aged group, and proceed to gain a further understanding of their daily trip pattern, trip chain, and daytime activity sequence . 76 older residents from a typical public housing neighborhood in Shanghai were asked to carry an Android Phone for 102 consecutive days. By collecting and analyzing the trajectory data, we found that even in a highly consistent social and physical environment, there are still significant differences among the elderlies’ daily activities, mainly existing in the age and gender aspects. The research indicates that elderlies’ daily trip patterns are related to the starting point, effective interval, travel time, and the physical conditions of the individuals.
