Numerical reservoir simulators are employed to obtain meaningful and reliable solutions for an actual case due to extreme complexity of the reservoirs systems. Wilcox formation is a reservoir in the gulf of Mexico with ...

A data-driven approach to solving the problem of excess water production was the focus of this study. In this research, several reservoir models were simulated for 26 years, and data obtained after simulation was used to ...

One of the ways of maximizing recovery from a reservoir is by drilling infill wells. Infill well placement is challenging because many well scenarios must be evaluated when undertaking the optimization program and very ...

In the past years, several researches have been done on gas-condensate reservoir recovery performance using fully compositional simulators. Fully compositional simulators are more expensive, time consuming and have complex ...

The first part of this study discussed in details the two major model that was developed for the study of a multilayer reservoir system. They are the Dual permeability model proposed by Bourdet and the semipermeability ...

Oil reserves are now located in hard-to-reach locations. This, combined with low oil prices, makes drilling for new reserves very expensive and risky. Enhanced oil recovery, which increases the amount of oil that can be ...

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 ...

Gas condensate reservoirs are initially discovered as single-phase gas reservoirs. As the reservoir is produced below the fluid dew-point pressure, an increase in condensate saturation in the near wellbore region occur ...

Reservoir development planning and well placement significantly affect hydrocarbon recovery. Therefore, strategic well placement and development techniques are essential to minimize the risk of unproductive drilling and ...

The study area which is the Niger Delta Province is predominantly an unconsolidated sandstone terrain, the sand grains are friable suggesting the expectation of some geomechanical problems while developing hydrocarbon ...

The use of horizontal wells with zonal isolations is a common completion practice in the oil and gas industry to check for very significant production challenges such as wellbore damage/skin, early water breakthrough and ...

In this study, we present a new analytical solution method that accurately corrects the non-isothermal effects from injection and fall-off tests. The derivative of these solutions is applied to develop the Tiab's Direct ...

Waterflooding is the most dominant secondary oil recovery method and its popularity is mainly due to the general availability of water, the relative ease of injecting water, the ability of water to spread easily through ...

Optimizing the placement of new wells and well spacing is a vital issue in oil field development. Drilling infill wells is one way to maximize the recovery of oil from reservoirs. The problem of infill well placement is ...

This research work mainly investigates the implication of void prediction in the estimation of total pressure gradient in vertical pipes for multiphase flow systems. Experimental data was collected for a multiphase flow ...

Clastic reservoirs may be heterogeneous and exhibit lateral and vertical variations in porosity and permeability. Therefore, the spatial distribution of the petrophysical properties within the reservoirs is important to ...

Gas condensate reservoirs are single phase at the initial condition. It changes to multiphase when the reservoir conditions are located between the critical point and the cricondentherm of the reservoir in the phase envelope. ...

The need to re-develop one of the Brown fields located in the Niger Delta area of Nigeria was necessitated by the fact that there are still three undeveloped reservoirs in the field. A total of six stacked reservoirs, A100 ...

The concurrent flow of gas/liquid in pipes poses a great challenge due to the difficulty associated with the flow of fluid. The flow is characterized by the existence of flow regimes which can be identified by the geometrical ...

From the inception of the oil and gas industry, water production has always been an aching problem for various operators. Throughout the productive life of a field, oil production is often accompanied with some amount of ...
