Water and gas injection techniques were compared, gearing towards improving oil recovery factor in Gas-Condensate Reservoirs. The primary input data of the model were estimated using average values of the field, separator recombined fluids and laboratory test data: total gas-condensate initially in place, recoverable gas and liquid volumes, permeab...

Locally non-polymeric de-emulsifier was formulated using locally available additives. The non-polymer de-emulsifier formulated was compared with the most common conventional de-emulsifier used in the Niger Delta oilfields. The two de-emulsifiers were subjected to the same condition of heat and chemical treatment at 60°F in a time interval of 1 to 3...

As a result of enormous uncertainties and high cost of drilling operations in the oil and gas industry, care must be taken to increase efficiency and reduce cost of drilling operations. The essence of this work was to employ laboratory analysis in finding and developing process of improving the suitability

Nature has given every country or community some natural resources. The extent to which each country or community utilizes its gifts of nature depends upon the level of that country’s technology. well developed country or community makes maximum use of it gifts of nature for the benefit of its citizens, because: - It can create a home in an ocean...

Water injection is a notable method used primarily for reservoir pressure maintenance and voidage replacement which boosts oil recovery. A problem associated with water injection operation is the injectivity loss due to rock porosity and fluid resistance to displacing oil to producing well, formation damage caused by accumulation of oil and solid p...

Natural gas compression volume to supplement gasoline fuelled vehicles in Nigeria and economic values models have been developed using Niger Delta natural gas production data. The importance of this research and innovation is to enhance diverse utilization investment (INV) of large scale with adoption of natural gas fuelled vehicles, improve perfor...

Natural gas fractionation components and economic values models have been developed in the Niger Delta. The importance is to enhance diversifying utilization, reduce gas flaring, creates fast development, impacts on building the Nation's economy, industrialization and jobs creation in the country. This was possible calculated average Natural gas va...

Models for natural gas fractionation have been designed to enhance diversifying utilization. Natural gas, a compound containing methane to heptanes plus was transmitted in 4- lines of similar streams. These lines were each fractionated based on business plans. The first stream was fractionated into two components liquefied petroleum gas for cooking...

Gas wells of mature gas field will inevitably produce liquid at some stage of their productive lives. As gas wells mature they produce liquid which flow together with gas. When the flow rate is not enough to sustain the critical velocity liquid condense out which flow as bubbles and later coalesce to slug and fall to the bottom of the well. The acc...

High accuracy evaluation models for predicting gas-reserves, recovery-factor and time were successfully developed, using production rate decline trend analysis. Existing gas data from wells in the Niger Delta geological formations (Agbada, Akata and Benin) were used to generate decline constants 'b' that were subsequently used in predicting yearly...
