... A deepwater Gulf of Mexico reservoir exhibits a simple geologic structure of a tilted sheet reservoir, three-way seal against salt. However, the (well-connected) oil column is complex and bimodal. The top half of the oil column exhibits an enormous gradient of gas-oil ratio (GOR) of 8000 scf/bbl...

... With the advent of dedicated OBN we routinely achieve excellent repeatability and low 4D noise levels in the Deepwater GoM. Clear 4D signals for reservoirs at depths down to 25000’ are regularly observed. For the field we select here, which is part-subsalt, we observe clear 4D signals at 23000...

... Groundwater undergoes dissolution along carbonate rock fault zones, leading to the development of different types of caves, pores, and fractured reservoirs along these fault zones, depending on the strength of the dissolution process. These different reservoir types exhibit different seismic...

... Present-day distributions of reservoir fluid properties result from mixing of gas and oil charges, over geologic time. Fluid mixing outcomes are highly variable, covering the whole range of reservoir realizations from simple equilibrated to complex disequilibrium distributions. Fluid dynamic...

... Seismic impedance inversion methods are widely used to obtain the impedance of reservoirs from seismic data. However, conventional inversion methods have many challenges to accurately estimate impedance of complex reservoirs. Deep learning has shown great potential in the field of seismic...

... This case study in the Oriente Basin demonstrates how integrated and weighted seismic post-stack and pre-stack attributes enable identification of upside potential as well as de-risking of well planning and execution in reservoirs with complex stratigraphic architecture within a mature oil field...

This inquiry harnesses sophisticated AI models including Artificial neural network (ANN) to develop a robust empirical correlation for critical oil flow using the most efficacious parameters for managing coning. The study presents a 3D reservoir simulation model that has been tested...

... Dolomite fines, referred to as dolo-trash and capable of migration through porous strata, were identified in porous (Leonardian) Clear Fork Formation reservoir rocks in Goldsmith field. During Clear Fork deposition the future site of Goldsmith field was positioned within the inner shelf...

... Conventional logging for reservoir evaluation relies on logging data and the manual setting of evaluation criteria to classify reservoirs. However, the complexity and heterogeneity of tight reservoirs make it a challengeable job in accurately classifying target layers using traditional well...

... With the deepening of unconventional exploration and development, geophysical prediction technology will run through the whole process of unconventional oil and gas exploration and development. M Area is a tight sandy conglomerate reservoir with low permeability. In the study area, the single...

... Conventional modeling methods for tight gas reservoir often consider procedures including fracture framework, geo-stress field, and fluid-solid interaction. The economic and human costs of the procedures are high because the procedures are driven by technique service companies and commercial...
