Potential use of hollow spheres in dual gradient drilling
(Texas A&M University, 2002)
The increasing number of significant deepwater discoveries has pushed the operator and service oil companies to focus their efforts on developing new technologies to drill in deeper water. Dual gradient drilling (DGD) ...
Analysis of condensate banking dynamics in a gas condensate reservoir under different injection schemes
(Texas A&M University, 2002)
If the reservoir pressure falls below the dewpoint pressure when producing a gas condensate reservoir, liquid dropout takes place in the reservoir. Liquid builds up in the near wellbore area causing what is known as a ...
Experimental study on the formation and dissociation conditions of methane hydrates in porous media
(Texas A&M University, 2002)
Gas hydrates are crystalline compounds formed when gas and water molecules are combined under low temperature and high pressure conditions. This study experimentally investigates the conditions leading to the formation and ...
Continuous Circulation System: a new enabling technology
(Texas A&M University, 2002)
Wellbore problems have existed since the very first oil well was drilled. These problems have cost the oil industry millions of dollars because they lead to substantial loss of valuable rig time, or even loss of the well. ...
A new approach for interpreting a pressure transient test after a massive acidizing treatment
(Texas A&M University, 2002)
Interpreting a pressure transient test from an acidized well in the framework of the thin skin concept is not straightforward for several reasons. First, the effect of stimulation cannot be considered to be localized in ...
A better understanding of a Uinta Basin channelized analog reservoir through geostatistics and reservoir simulation
(Texas A&M University, 2002)
The Green River Formation is located in the Uinta basin of northeastern Utah. It contains several reservoirs that can be classified as lacustrine such as the Altamont-Bluebell and Red Wash. Lacustrine reservoirs are ...
Experimental study of enhancement of injectivity and in-situ oil upgrading by steam-propane injection for the Hamaca heavy oil field
(Texas A&M University, 2002)
Experiments were conducted to study the feasibility of using propane as a steam additive to accelerate oil production and improve steam injectivity in the Hamaca field, Venezuela. The experiments utilized a vertical ...
Experimental study of oil yields and properties of light and medium Venezuelan crude oils under steam and steam-propane distillation
(Texas A&M University, 2002)
Six experimental runs were carried out to study the yields for a light crude oil (34.2°API) and an intermediate crude oil (25.1°API) under steam distillation and steam-propane distillation. Yields, were measured at five ...
Development of neural network models for the prediction of dewpoint pressure of retrograde gases and saturated oil viscosity of black oil systems
(Texas A&M University, 2002)
Accurate prediction of gas condensate and crude oil fluid properties are critical elements in reservoir-engineering calculations. Dewpoint pressure of gas condensate reservoirs and oil viscosity of black oil systems are ...
Performance of a well with lateral and vertical wellbores
(Texas A&M University, 2002)
This thesis presents three major topics: analysis of pressure transient behavior of horizontal wells, analysis of pressure transient behavior of slanted wells, and performance analysis of wells with lateral and vertical ...
