Pressure build-up data in low permeability reservoirs take too long and are usually of poor quality. A pressure buildup test is perhaps the most widely performed transient test. In pressure buildup test, a well which has ...

Cuttings transportation during in non-vertical boreholes is necessary for oil and gas wells. Adequate cuttings removal from a well in drilling is critical for cost-effective drilling as high annular cuttings buildup often ...

Unconventional resources are of major importance to the oil and gas industry due to its enormousness, however, due to the low permeability of these resources, there is a need for hydraulic fracturing. Hydraulic fracturing ...

Proper handling of sour gas produced is crucial to the development of sour reservoirs. Over years of research and practice, many methods of sour gas processing have been developed from the solid storage of sulfur to ...

Appropriate selection of rheological models is important for hydraulic calculations of pressure loss prediction and hole cleaning efficiency of drilling fluids. Power law, Bingham-Plastic Herschel-Bulkley models are the ...

Data-driven analytical models are important tools employed in the petroleum industry to forecast production rates and reserves of petroleum assets. Studies have shown that existing rate forecasting models project future ...

Slug flow along slightly inclined horizontal pipes is a major problem in gas-liquid transportation, it is very pronounced in chemical, oil and gas processing industries. In reality, there is no absolute horizontal pipe due ...

The effect of liquid flow rate, pipe size (diameter) and pipe orientation (inclination) on liquid hold-up was investigated. Liquid flow rate between 500 STB/day and 5000 STB/day was studied. An oil of 25 ̊API at an average ...

The main challenge of heavy oil (bitumen) is the high viscosity making it not flow easily to production wells at normal reservoir conditions. Thermal recovery methods are used to exploit heavy oil reservoirs, where oil ...

Increasing oil recovery has been one of the issues enlisted for attention in oil producing countries around the world for past decades. So many forms of oil recovery techniques have been considered; infill drilling of new ...

Down-hole temperature and pressure data are important information needed to understand flowing conditions and production optimization. For example, knowing the wellbore temperature profile is useful in predicting the wax ...

The concept of dumpflooding is to flow water from a high pressure aquifer zone to a low pressure oil producing zone by natural force of gravity through a well connecting the two zones to enhance oil sweep into a producing ...

In the estimation of most reservoir parameters in well test, the reservoir is assumed to be isothermal which is practically not true due to the fact that there are heat sources due to friction in the wellbore, works done ...

A gas condensate reservoir is a type of gas reservoir that exists when the reservoir temperature is between the critical temperature and the cricondentherm. Compositional simulators are used to simulate these types of ...

A gas condensate reservoir is a type of gas reservoir that exists when the reservoir temperature is between the critical temperature and the cricondentherm. Compositional simulators are used to simulate these types of ...

There is insufficient literature for annular flow and applications of Machine Learning in the petroleum industry; thus, this thesis is centred on annular flow prediction. Liquid holdup and flow behaviour during annular ...

One of the important petrophysical parameter in reservoir description is the permeability distribution in a given reservoir. It is well known that most reservoir are heterogeneous in nature and homogeneous ones been the ...

Waterflooding is a secondary recovery process in which water compatible with the reservoir of interest is injected into the reservoir to displace residual oil. The goal of waterflood management is to maximize oil recovery ...

The practical application of various production parameters and relations to predict the well performance analysis of a solution gas drive reservoir is the primary objective of this study. These parameters include: IPR ...
