03: What we see on a seismic record
Переглядів 1189 місяців тому
When looking at a seismic shot record, we see different seismic trends, including direct and refracted waves, reflections, multiples, ghosts, and ground rolls. To process seismic data, the first step is to identify these events. In this video, you will learn how to discern different seismic events on a shot record.

How does gas production differ from oil, and why? Why aren't there any organizations, such as OPEC for the global gas market? What challenges are associated with gas marketing? In this video, you will discover some interesting information about natural gas production and marketing.
Hydrocarbon Behavior in the Reservoir (T-P diagrams)
Переглядів 34311 місяців тому
To achieve the best possible production from a hydrocarbon reservoir, understanding the behavior of hydrocarbons during production is essential. This understanding can be attained through the analysis of a temperature-pressure diagram. In this video, I discuss temperature-pressure diagrams and how they can be utilized to formulate the best strategies for optimized production.
NMR Log-Formation Evaluation
Переглядів 2,4 тис.11 місяців тому
Nuclear Magnetic Resonance (NMR) is a versatile logging tool that offers various pieces of critical information, including porosity, pore size distribution, effective porosity, permeability, oil viscosity, gas density, hydrocarbon type, etc. Therefore, compared to conventional logging tools, NMR is robust in terms of the variety of data it provides. In this video, I delve into NMR.
Sonic Logs-Formation Evaluation
Переглядів 2,5 тис.Рік тому
Sonic logging tools measure the travel time of seismic waves in the formation, from which we can estimate the primary porosity. By using the sonic porosity, we can further estimate the secondary porosity index, which serves as a measure of the fracturing level in the formation.
Neutron Porosity Log-Formation Evaluation
