... Abstract Understanding the fluid-flow characteristics in reservoir rocks requires a reliable assessment of permeability and saturation-dependent relative permeability. It is also essential for quantifying the primary recovery mechanisms and enhancing the ability to exploit reserves...

... Abstract Objectives/Scope: Proper assessment of reservoir depletion by offset development is essential for well spacing and completion optimizations, particularly in infill developments. Typically, such assessment is available after new wells are completed or eventually put on production...

... Abstract This paper outlines how modern horizontal well completion designs and stimulation techniques are being further optimized with new assessment techniques and leading to even more efficient operations and evenly stimulated stages along longer laterals in the reservoir. Chevron wanted...

... Abstract Unconventional shale formations pose unique challenges and opportunities for hydrocarbon extraction. This study focuses on the Abu Roash Formation (ARF) in Egypt's Western Desert, aiming to assess its potential as an unconventional reservoir. Leveraging insights from successful North...

... instant and does not require human synthesis and calculation of the data which must then be relayed to the rig. Theory and Method The use of drilling data to detect pore pressure is rooted in the fundamental assessment that drilling a well disturbs the stress state of the subsurface. As pore fluid...

... Abstract Unconventional wells have been known to revolutionize the oil and gas industry in the last decade. The downhole diagnostics play an essential part in understanding the well completion and reservoir performance. Main objectives for the downhole surveys can include: – Assessment...

... Production and Optimization Program (BPOP), and will cover 1) a review of the wells that have been refractured in the North Dakota portion of the Bakken petroleum system (BPS), 2) an evaluation of production performance of the refractured wells, 3) an assessment of refracturing economics, and 4...

... (in less detail) to assess the heat flow vertically among targets. The properties were initially upscaled using arithmetic averaging and then modeled in 3 dimensions using sequential gaussian simulation. The 3D porosity and permeability models provided an understanding of the reservoir quality along...

... Abstract Some of the underperformance encountered in the petroleum industry is attributed to cognitive biases in project assessments (estimates or forecasts). It has been shown in the literature that if biases are reduced, portfolio profitability is increased. We will demonstrate that biases...

... Abstract Fluid characterization and correct volumetric assessment can be very difficult to quantify in saturated fluid systems. Commonly, during initial fluid sampling, the flowing sand face pressure condition is less than saturation pressure, leading to multiphase flow. In this common...

Our results show that hydraulic fracturing water use intensity (HFI), true vertical depth...

... Abstract The U.S. Geological Survey (USGS) recently completed an assessment of water and proppant demands associated with petroleum production from the Upper Cretaceous Eagle Ford Group in South Texas. The water and proppant assessment builds on the 2018 petroleum assessment conducted...

... Abstract Reliable fluid saturation assessment in organic-rich mudrocks has been a challenge for the oil and gas industry. Composition and spatial distribution of rock components have a significant impact on electrical resistivity and, thus, on hydrocarbon reserves estimates. Clays are typically...
