There is currently a lack of understanding how sport psychology practitioners navigate the nuances working within esports domain in applied literature. Therefore, current case study provides three confessional tales, which aim to outline unique experiences two and exercise psychologists training, with national Overwatch team during World Cup preparation period. We first provide contextual elements format, roster, team’s needs, program work. In form we share series critical reflections...
Time-lapse seismic data play a key role in hydrocarbon field monitoring and infill opportunity development. In several deepwater hydrocarbon-producing reservoirs, time-lapse softening changes have been observed at the oil-water contact. Here, we refer to this as contact softening. Contact occurs when acoustically softer hydrocarbons above invade replace stiffer brine pore space below This typically pressure depletion from production elsewhere is transmitted through shared aquifer, causing...
Our study shows that time-lapse changes in the amplitude of seismic reflection at an oil–water contact (OWC) and/or produced OWC can be used to estimate directly displacement efficiency water displacing oil, E D , without need a rock and fluid physics model. From this value, it is possible determine remaining oil saturation if required. A preliminary application performed using several published literature examples, which are reinterpreted assess average ensure theory consistent with...
We present examples of 4D time-shifts obtained with offset and angle sub-stacks seismic data acquired in deep (Gulf Mexico) shallow water (North Sea) marine environments. compare the observations two proposed rock-physics models using different linear relationships between velocity change strain field induced by reservoir compaction. The model involving only vertical component predicts a similar time-shift behavior as that observed from data. do not observe strong decrease reported previous...
Abstract The Southern North Sea is a mature gas basin, producing mainly from faulted Permian Rotliegend sandstones. Identifying infill well opportunities in un-depleted or partially depleted blocks these fields challenging, particularly if the sealing capacity of faults within field uncertain. Time-lapse (4D) seismic monitoring provides an opportunity to identify reservoir by measuring differences travel time across interval between surveys acquired before and after production. 4D tests were...
A case history from the West of Shetlands, UKCS, demonstrates that careful planning and acquisition a 4D repeat/monitor towed streamer survey provided significant improvement in repeatability. This was achieved by ensuring source receiver locations for baseline monitor were repeated as closely possible. Close interaction between oil companies specialist contractors during execution phases ensured required level repeatability achieved. Comparison with previous repeat survey, acquired two...

The role of sport psychology practitioners in contributing to the drafting process athletes teams, by providing their input on athletes’ psychological makeup, has become a common practice. Similar traditional sport, esport organizations also engage periods identify next talents. Yet, paucity literature exists examining practitioners’ experiences operating during such trial context. In this case study, we outline our being involved as and exercise psychologists training professional National...
We present two confessional tales of our transnational experience as U.K.-based trainee sport psychology practitioners working in a professional organization Trinidad and Tobago. first provide contextual elements placement before sharing the regarding nuances providing services cultural context different from one which we are currently training. In tales, share some challenges hurdles experienced relating to culturally led assumptions. The titled “Boundary Issues” “Punctuality Is Privilege.”...
Sport psychology practitioners are increasingly operating in the esport domain. Yet it remains unclear how who have exclusively been trained traditional sport develop a contextually grounded understanding of their practice esport. This study, framed from an ontological relativism and epistemological interpretivism approach, involved semistructured interviews with 10 qualified (three female, seven male) transitioned to Data were analyzed using reflexive thematic analysis presented via three...

Summary Several models have been recently proposed to connect observations of velocity change with strain deformation in and around reservoirs undergoing production recovery. In this work we show that a simple compliance-based model combined the original conceptual understanding Hatchell Bourne (2005) can adequately explain magnitude R factor values currently observed from calibrated field data variety settings. The is also used determine an expression for gradient overburden time-shift...
Time-lapse 4D seismic data acquired over the Gannet F Field has allowed inferences to be made about extent of thin bedded reservoirs in field, and identified some unexpected fluid flow between different reservoirs.
