... in an economic and timely fashion to allow for large-scale CO 2 sequestration. A promising option to boost storage capacity would be to retrofit some of the nation's millions of legacy oil and gas wells for use as sequestration wells. We present an analysis of wellbore retrofit, the process of augmenting an old...

... One of the causes of pressure variations in a reservoir setting is the thickness and differential rate distributions across the reservoir. Damage around the wellbore area also contributes to the degree of pressure variations from adjoining wells within the reservoir. The damage radius, r d...

..., the additional pressure required during flowback is needed to produce the water used during fracturing. The reservoir energy to lift this water to the surface requires more pressure drop around the wellbore. Additionally, unnecessary water used during fracing operations incrementally increases the pressure drop...

..., resulting in weakening hydrocarbon-bearing rocks. Drilling issues such as wellbore stability, loss circulation, differential sticking, formation damage remarkably influenced by the pore pressure decline, increasing the risk of losing part or even all the horizontal interval. This paper presents an extensive...

... Abstract Asphaltene precipitation and deposition occur in the reservoir, near-wellbore, inside the tubing, and production facilities during primary, secondary, or tertiary production. As more water-flooded oil fields produce under miscible gas flooding, this problem becomes more common around...

For a long fall-off period, formation recharge may appear with a slope between unit and 1.5 slopes derivative, especially in over-pressured dry gas reservoirs. Analyzing fall-off data after stages...

We use as a measure, the SOR (Steam Oil Ratio) to ascertain the optimality of the conversion points and compare it to our modeling work. During the CSS process, steam injectivity is gradually...
