(2017-04-03)Oil and gas production, industrial manufacturing, mining, and agriculture all produce significant amounts of wastewater, often containing harmful heavy metal ions such as cadmium, lead, and arsenic. Radioactive disasters ...
-
(Texas A&M University, 2006-10-30)This study presents a simplified and accurate procedure for selecting the rheological model which best fits the rheological properties of a given non- Newtonian fluid and introduces five new approaches to correct for tool ...
-
(2013-05-03)A model for the evaluation of CO2-EOR projects has been developed. This model includes both reservoir simulation to handle reservoir properties, fluid flow and injection and production schedules, and a numerical economic ...
-
(2017-12-07)According to the 2014 EIA statistics, natural gas production from shale and tight oil plays accounted for 48% of US natural gas production and this number is expected to grow to 69% in 2040. Natural fractures are commonly ...
-
(2017-05-01)Successful exploitation of unconventional resource plays relies on the massive hydraulic fractures which provide high conductive paths and large contact area between formation and wellbore. The pursuit of efficiency and ...
-
(Texas A&M University, 2005-11-01)According to the Texas Railroad Commission (TRC), ????over 250 billion gallons of produced water is taken out of Texas Soil every year, and more than 35% of this water is not currently fit to use.?? Therefore, it can be ...
-
(2018-07-31)The objective of this study was to perform analysis in to the mechanisms of motor failure in the curve lateral portion of an operator’s high temperature Eagleford shale wells. This was achieved through multiple high frequency ...
-
(2009-05-15)Petroleum coke or petcoke, a refinery byproduct, has generally been considered as an unusable byproduct because of its high sulfur content. However energy industries now view petcoke as a potential feedstock for power ...
-
(2015-08-05)The presence of complex water-in-oil emulsions is a growing concern in heavy oil recovery due to the complexity and expenses involved in separating the water from the produced oil. Hence, it is of paramount importance to ...
-
(2012-12-11)Natural gas is an important energy source that contributes up to 25% of the total US energy reserves (DOE 2011). An increase in natural gas demand spurs further development of unconventional resources, including methane ...
-
(2014-12-18)Concerns about the substantial amounts of water and chemicals pumped into the subsurface during hydraulic fracturing are valid because long term effects of these stimulation actions are unknown at the present time. Although ...
-
(2014-09-24)Properties of both shale gas reservoirs and hydraulic fractures are usually estimated by analyzing hydrocarbon production data while water data is typically ignored. This study introduces a new method to estimate the ...
-
(2013-02-08)In this work, I present the development of analytical solutions in the Laplace domain for a fully-penetrating, horizontal well producing at a constant flow rate or constant wellbore pressure in the center of a composite, ...
-
(2018-08-06)Oil and gas producers around the world face a major challenge in estimating zonal flow contributions in wells with multiple pay zones. This study develops an analytical approach that estimates zonal flow contributions from ...
-
(2017-07-20)Since their introduction to the petroleum literature in 2008/2009, the stretched exponential (SE) and the power-law exponential (PLE) relations have become the "conservative" standard for time-rate (decline curve) analysis ...
-
(2012-02-14)Numerical simulation has been used, as common practice, to estimate the CO2 storage capacity of depleted reservoirs. However, this method is time consuming, expensive and requires detailed input data. This investigation ...
-
(2017-04-18)This research presents an analytical 1D radial-flow model for estimating the transient flowing-fluid temperature in a single-phase oil reservoir. The model allows fluid density, viscosity, and the J-T coefficient to vary ...
-
(Texas A&M University, 2006-08-16)Fracture-injection/falloff sequences are routinely used as pre-frac well tests to estimate reservoir pressure and transmissibility, but the current interpretation methods are limited to analyzing specific and very ...
-
(2014-11-13)Modern downhole temperature measurements indicate that bottomhole fluid temperature could be significantly higher or lower than the original reservoir temperature, especially in ‘more challenging’ low-permeability reservoirs, ...
-
(2013-09-29)Two methods of hydraulic fracturing most widely utilized on unconventional shale gas and oil reservoirs are “gelled fracturing” and “slick-water fracturing”. Both methods utilize up to several million gallons of water-based ...
