Borehole data obtained during a drilling process can greatly improve the understanding of evolving reservoir characteristics and conditions. Drilling logs and sensor data such as gamma ray, resistivity, and dipmeter can provide engineers with a wealth of additional geologic detail associated with a borehole. When newly-acquired borehole datasets are combined with existing reservoir data, then…
When developing well-collision avoidance strategies, petroleum professionals should rely on data integration and visualization to aid in well planning. Enhanced visualization gives engineers the ability to see more of the subsurface and provides them with additional opportunities to prevent drilling into danger zones or colliding with established wells. There are two software tools that asset…
The ability to visualize data that characterize a wide array of subsurface conditions and environments, including geology, lithology, geophysics, wellbores, casings, completions, oil, gas, water, and production data is dramatically changing the way engineers approach petroleum planning and analysis. Beginning with initial seismic surveys and building an archive of data generated throughout the life of…
There are two main classes of oil well production problems—mechanical and reservoir. In both classes, much of the same unstructured data can be used to diagnose and resolve the problem but it is the resolution processes that differ once the source of the problem is identified. When resolving oil well production problems, engineers and geoscientists…
New Tools, New Paradigms, New Discoveries By using natal charts, colorful geological maps, deep magnetic field analyses, and ephemerides of various astral objects, a comprehensive picture for optimal well surface location and hydrocarbon exploitation can be achieved with 3D and 4D diverse data integration software and astrocartographic workflows. Integrating disparate data found in the oil…
Modern seismic, drilling, and production technologies allow petroleum engineers to generate or acquire substantial volumes of data that characterize well performance—from initial exploration up to yesterday’s production metrics. These data can provide valuable insight when reservoir engineers are considering wells to be drilled into offset prospects or wells drilled to extend an existing producing reservoir.…
Efficient oilfield development requires a multidisciplinary team that consists of geologists; geophysicists; reservoir, drilling, facility, production, and logistics engineers; and more. This phase of operations is where the majority of the data is acquired and requires the most investment capital. When looking to enhance this phase of operations to maximize recovery, petroleum professionals need to…
Tracer technology for the oil and gas industry has become an increasingly important tool for reservoir surveying and monitoring. Tracers can help portray reservoir characteristics more clearly, depict fluid pathways, reveal communication—planned or unexpected—between wells, and provide better estimates of remaining oil saturation. Tracer technology in oil and gas has become indispensable for showing fluid…
A mechanical issue in a well is a common occurrence, but issues found in more than one well could indicate a larger problem within the reservoir. To avoid reservoir dilemmas that can hamper well-placement strategies and incur long-term costs, analysts need a complete visual of the reservoir. To prevent operational stalls, analysts also need accessible…
A bad completion can ruin a well and waste millions of development dollars. Petroleum engineers who know how to exploit the inherent value of subsurface geologic and wellbore data are better prepared to design, drill, and complete wells to safely deliver maximum oil recovery. Every stage of the development process yields additional data that…
