Modeling and Simulation of Reservoir Formation Damage due to Chemical Precipitation and Particulate Processes
(2011-11-20)
Formation damage is an undesirable operational and economic problem that can occur in many phases of field development including drilling, completion, workover, production, stimulation, waterflooding and enhanced oil ...
Practical Approaches for Solving Lost Circulation Problems while Drilling
(2011-12-12)
As the demand for petroleum resources increases, drilling of oil and gas wells are often carried out in challenging and hostile environments. Among the top ten drilling challenges facing the oil and gas industry today is ...
Evaluating Uncertainty in the Volumes of Fluids in Place in an Offshore Niger Delta Field
(2011-12-12)
The purpose of this work is to evaluate the uncertainty in the volumes of fluids in place in Fault Block A (Segment 3) of the G-1 Sands in the OND field located offshore Niger Delta. The evaluation was performed in three ...
Investigating Horizontal-Well Interference Test Applications
(2011-11-20)
One of the major challenges in reservoir engineering is the accurate description of the reservoir. This description is essential in all aspects of petroleum
engineering, and is typically achieved through reservoir ...
Vertical-Horizontal Permeability Relationships in Stress and Non Stress Sensitive Reservoirs
(2011-12-12)
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 ...
Measurements of the structure of turbulent premixed and stratified methane/air flames
(University of CambridgeDepartment of Engineering, 2011-11-08)
The influence of stratification on the structure of turbulent methane/air combustion is investigated using experimental data from laboratory scale burners: a weakly turbulent slot burner, and a higher turbulence co-annular ...
Stochastic hub and spoke networks
(University of CambridgeJudge Business School, 2011-10-11)
Transportation systems such as mail, freight, passenger and even telecommunication systems most often employ a hub and spoke network structure since correctly designed they give a strong balance between high service quality ...
Ultra-High Speed Particle Image Velocimetry on Drop-on-Demand Jetting
(Proc 27th Int. Conf. on Digital Printing Technologies NIP27, 2011)
An experimental setup to study the dynamics of droplet jetting from a commercially available print-head is described. A MicroFab print-head with an 80 µm
diameter transparent nozzle was set to print droplets at a speed ...
Experimental investigation of the impact, spreading, and drying of picolitre droplets onto substrates with a broad range of wettabilities
(2011-10-02)
The effect of the substrate wettability on the deposition of
picolitre droplets by drop-on-demand technology is investigated
experimentally. Substrates with a broad range of wettabilities are
considered with contact ...
The dynamics of the impact and coalescence of droplets on a solid surface
(Biomicrofluidics, 2011)
A simple experimental setup to study the impact and coalescence of deposited droplets is described. Droplet impact and coalescence have been investigated by high-speed particle image velocimetry. Velocity fields near the ...
