...Jamal Daneshfar; Richard G. Hughes; Faruk Civan The rate of CO 2 production in many states, primarily from coal-fired power plants, is such that it only takes a few years to fill up any depleted oil and gas reservoirs. In order to reduce the level of CO 2 in the atmosphere and to minimize the cost...

...Aldo Costantini; Gioia Falcone; Geoffrey F. Hewitt; Claudio Alimonti The fundamental understanding of the dynamic interactions between multiphase flow in the reservoir and that in the wellbore remains surprisingly weak. The classical way of dealing with these interactions is via inflow performance...

...Binshan Ju; Xiaofeng Qiu; Shugao Dai; Tailiang Fan; Haiqing Wu; Xiaodong Wang The coning problems for vertical wells and the ridging problems for horizontal wells are very difficult to solve by conventional methods during oil production from reservoirs with bottom water drives. If oil...

..., the Joshi model predicts a 0.0 stb∕day-psi PI, which is wrong. In this paper, the flow for a horizontal well is divided into three flows: the flow in the reservoir above the horizontal wellbore, the flow in the reservoir with a thickness of 2 r w containing the horizontal wellbore, and a flow...

... to be viable. The ability to predict and control such formation damage can thus become critical to project success under such circumstances. The work described in this paper presents how the risk may be managed from early in the CAPEX phase of projects through to the OPEX phase by use of reservoir simulation...

...D. Brant Bennion; F. Brent Thomas Very low in situ permeability gas reservoirs ( Kgas < 0.1 mD ) are very common and represent a major portion of the current exploitation market for unconventional gas production. Many of these reservoirs exist regionally in Canada and the United States and also...

... reservoir pressure; an optimum area ratio for the gas/liquid pistons is approximately 40. The effect of friction in the pumping system was predicted to have a small effect on this optimum design. The results of this investigation will now be used to design and construct a prototype for field testing. 25...

...L. Guan; D. A. McVay; J. L. Jensen; G. W. Voneiff Background. Identifying the locations and amounts of unproduced gas in mature reservoirs is often a challenging problem, due to several factors. Complete integrated reservoir studies to determine drilling locations and potential of new wells...
