Seismic signature of sedimentary rocks with CO₂ flooding
(2012)
Surface seismic offers a promising technique to monitor CO₂ flood fronts during enhanced oil recovery process. Changes in seismic signature have been observed with CO₂ flooding but quantification of the seismic signature ...
Stable nitrogen isotope signal in crude oils throughout geologic time
(2017-05-12)
Stable nitrogen isotopic compositions of asphaltene and NSO hydrocarbon fractions from sixty-two crude oils derived from siliciclastic, carbonate/marl, hypersaline and lacustrine source rocks of known geologic age ranging ...
Inferring Interwell Connectivity by Statistical Diagnostic Tools and Signal Processing Methods
(2018-12-14)
Data mining has become increasingly crucial in deciphering reservoir dynamics. Operators currently acquire an enormous amount of data that are not effectively being used. These data contain valuable information about ...
PERFORMACE OF UREA-BASED IN-SITU CO2 EOR: INFLUENCES OF DIFFERENT POROUS MEDIA
(2018-12-14)
Carbon dioxide (CO2) flooding has been proved as a successful method for enhanced oil recovery (EOR) in oil fields globally in recent decades. However, significant growth of applying CO2-EOR technology is largely restricted ...
Non-Destructive Index Testing For Relative Assessment Of Rock Strength
(2016)
Index tests for the determination of rock properties have been employed since the early 90s, based on methods developed since the 1900s in the metallurgical industry. Examples include the Brinell hardness test, Rockwell ...
UNCERTAINTY ANALYSIS OF PRODUCTION FORECAST IN SHALE SYSTEMS
(2019-05-10)
This research evaluates the impact of decision making and uncertainty associated with production forecast in shale oil and gas wells; over 11000 wells completed in the Barnett & Haynesville plays and more than 2000 wells ...
Numerical simulation of transient cuttings transport with foam in horizontal wells
(2013)
The use of foam for underbalanced drilling applications is increasing significantly. This is because foam exhibits properties, which are desirable when drilling depleted and low-pressure wells. However, a good knowledge ...
Surface Area Study in Organic Rich Shales using Nitrogen Adsorption
(2017)
Low-pressure nitrogen adsorption technique was used to investigate the specific surface area and pore size distributions and controlling factors for 11 wells from seven different shale formations with varying thermal ...
AUTOMATION AND INVESTIGATION OF INTELLIGENT DRILLING AND ITS IMPLEMENTATION IN EXPERIMENTAL SETUP
(2019-05-10)
On January 9, 1845, Robet Beart in Great Britain was granted a patent on the first of a new style of rig, the rotary rig with continuous circulation [21]. Since then, not many advancements have been made in drilling ...
Importance of Capillary Heterogeneity in Developing a Representative Reservoir Model for Shales with Complex Fractures
(2016-12-16)
Our advancement in hydraulic fracturing has enabled us to produce shale formations economically. The formation stimulation is successful when the effective transport properties of the formation is improved significantly, ...
