Analysis of shaly sand reservoir rocks in the eastern Niger Delta Basin using geophysical well logs

Hydrocarbons in the Niger Delta Basin are produced predominantly from the Agbada Formation which is a major intercalation of shales and sandstones. Shales in the reservoir can cause complications for the petrophysicist because they generally are conductive and mask the high resistance characteristic of hydrocarbons. Data from a suite of well logs comprising of gamma ray, spontaneous potential, resistivity, neutron and...

Effect of heavier hydrocarbon fraction in optimum surface separation condition

The hydrocarbons fluids are separated on the surface before they are sent to the market. There are several factors affecting the hydrocarbons surface separation conditions, pressure and temperature are the main studying factors. To obtain stabilized hydrocarbons phases optimum surface separation pressure and temperature must be selected. Several empirical models have been developed to obtain optimum surface separation...

Testing and Analysis Rheological Properties of Water Based Mud Using New Organic Additives

Polymers which are used as fluid loss control agents are commonly organic and are used in both circulating as well as non-circulating phases of drilling operations. Drilling costs associated with these types of agents are very high contributing to 5 – 15% of total drilling costs and hence it is very important to find a substitute for these additives that can be used for same purpose but at lower drilling cost and at better...

The sulphur content in refined petroleum products namely diesel (AGO), kerosene (DPK) and gasoline (PMS) obtained from a commercial Filling Station in Abakaliki, Ebonyi State were determined before and after desulphurization with aqueous ionic solutions of NaOH, BaCl2, Ca(OH)2 and HCl using a single beam UV-Vis spectrophotometer (Genesys 1OS, Thermo-Scientific). Results obtained showed that the amount of sulphur contained...

Laboratory study of rheological properties of novel drilling fluid

Rheological specifications of drilling mud which contains nano zinc oxide ( 1 gr) in high temperature – high pressure viscometer are considered in this work to simulate the drilling conditions occurred in deep wells. Shear stress, shear rate, effective viscosity, plastic viscosity and gel strength are measured versus temperature (30, 40, 50, 60, 70 and 80 C) and working time (0, 1, 3, 5, 7, 10, 12 and 15 days). Also,...

Enhanced Oil Recovery Practices: Global Trend, Nigeria’s Present Status, Prospects and Challenges

Unimpressive oil recovery characterized by declining oil rates and increasing water cut and gas-oil ratio trend necessitates the need for enhanced oil recovery (EOR). However, at present, EOR is yet to be applied in Nigeria, though it was reported that by December 2008 approximately 52 billion barrels of crude oil were potential targets for EOR in Nigeria. It is against this background that this paper reviews the global...

Numerical Investigation of Rock and Fluid Properties on Water-Oil Relative Permeability Curves by Design of Experiment Method

Relative permeability curves crucially control fluids displacement and reservoir performance in any fluid injection process and EOR projects. Unsteady state core flood test, considered in this study, is the most common method to calculate relative permeability curves. Ignoring capillary pressure and core heterogeneity, the well-known Johnson, Bossler and Neumann (JBN) method is usually used to calculate kr curves in these...

High resolution infill drilling modeling: A viable tool for effective field development and optimization

The drive for infill drilling is capacitated by the sudden quest for oil and gas development and optimization particularly in the Niger Delta has critical geotechnical constraints such as the favourable position, number of wells and even to know when the well should come on stream. The aim of this study is to apply the above statement with the view of determining the reasonable maximum cumulative gas to be produced and to...
