    Abstract: The loss of circulation is an extremely unhealthy phenomenon for drilling, as the liquid solution leaving in the reservoir often leaves the entire drilled breed in the borehole and, in most cases, all the large particles in the solution itself. The settling masses are compacted and can create around the drill tool dense shell and also cause so-call... Show More

    Abstract: This paper presents experimental findings on upward swirling liquid film for both single-phase and two-phase gas-liquid flow in a vertical gas-liquid cyclonic separator. The upward swirling liquid film is one dynamic phenomenon that occurs in pipe cyclonic separator. The upward swirling of the liquid film in the upper part of the cyclonic separator... Show More

    Abstract: In order to counter-balance the formation pressure, the drilling mud is weighted up using a chemical additive, usually Barite. The usability of locally sourced Nigerian Barites on the major types of drilling fluids in conventional conditions is presented. Water-Based mud, Oil-Based mud and Synthetic-Based mud formulations with locally sourced Barit... Show More

    Abstract: Oil rim reservoirs present unique problems during production. This is because of the proximity of the water and/or gas to the oil in the pay zone leading to phase distortion due to pressure disequilibrium during production of the oil. The resultant effect is early water/gas breakthroughs which ultimately lead to increased well operational cost, dam... Show More

    Abstract: The ability to detect leak is crucial in pipeline fluid transport operations. Leaks will inevitably occur in pipelines due to wide range of uncertainties. A good leak detection system should not only be able to detect leak but also accurately estimate the actual time of leak occurrence. This will enable proper estimation of the fluid loss, from the...

    Abstract: In order to carry out hydrocarbon production in the basement, a drilling must be carried out and the latter crosses several layers or formation until reaching the desired objective. At the beginning of the production, the well will have a natural pressure and the oils in a reasonable quantity which will allow to make an exploitation but over time t... Show More

    Abstract: This work evaluates the economics of GTL plant using two synthesis gas methods. The first method called the base case utilizes oxygen as fuel for combustion of natural gas, while the proposed case uses steam/CO2 instead of Oxygen. The aim is to ascertain a more economically viable GTL configuration for an optimal GTL process. The associated flare g... Show More

    Abstract: This paper evaluates method for optimisation of GTL plant using Steam/CO2 reforming for syngas generation. Extensive modelling of GTL plant has been done. Two cases were considered during the simulation of the GTL plant. The first case was the use of oxygen gas as the feed reactant gas using an auto-thermal reformer for the production of synthesis ...
