COMPUTATION OF CONSOLIDATION CONSTANTS FROM THE CONSOLIDATION TEST
By ACHOR ENGINEERING LTD

The two important quantities which have to be determined in the consolidation test are the coefficient of compressibility Mv and the coefficient of consolidation Cv. From a knowledge of MV the total settlement can be estimated. The rate of settlement is estimated from a knowledge of Cv.

USES OF SHEAR TESTS

The laboratory shear test has to produce the possible mode of failure of the soil under the actual site conditions.

The type of shear test to be used will therefore depend on the nature of the problem to be investigated,and a few typical examples are given.

Clay soil below building foundations are usually loaded by the foundations at such a rate that only very little drainage will have taken place at the time of the completion of the building.

The actual building period may be one or two years,but the process of dissipation of the excess pore pressures which are caused by the load of the building may go on for many years. The undrained shear test is therefore appropriate.

LATE SANTONIAN TO EARLY CAMPANIAN PALYNOSTRATIGRAPHY AND PALAENVIRONMENT OF KEMAR-1 WELL, BORNU BASIN,NORTHEASTERN NIGERIA.
By Olofinnade M.

Oil production is the cornerstone of Nigeria's economy ranks as the largest oil producer in Africa. Presently, Nigeria has been rated as the largest oil producing country in the world, with a proven ultimate reserve of thirty billion barrels of oil and two hundreds and sixty trillions cubic feet of natural gas.

Quite a number of exploration campaign have been undertaken and some are still ongoing in the sedimentary basin of Nigeria with the sole aim of expanding the national exploration and production base and to thereby add to the proven reserves asset.

As a result of this, the Bornu basin, the largest area of inland basin and the southeastern sector of the chad basin, has experienced petroleum activities in the last two decades base on the discovery of commercial hydrocarbon in the Niger and Chad portions of the chad basin.

Intact recent discovery of commercial quantity of hydrocarbon in the cretaceous Anambra basin has strengthen the attention on the Borno basin as a member of in-land basins in Nigeria.

LOW ENERGY BUILDING AND THE MITIGATION OF THE IMPENDING DANGER OF CLIMATE CHANGE IN OGUN STATE (Paper 1)

By Olofinnade M.
+2349027136464

Low Energy buildings use passive techniques, such as optimal solar gain, and advanced active systems, such as mechanical ventilation with heat recovery, to create comfortable internal environments that have low energy demand and associated greenhouse gas emissions.

Some low energy buildings use renewable energy generation to further reduce or eliminate their greenhouse gas emissions in us.

Good design can cut CO2 and energy bill by nearly two thirds and incorporating renewable energy can produce buildings that require no active power source thereby reducing the level CO2 in the atmosphere.

5- Geoscientists / Georesearchers / Geology - Hydrogeology /hydrology / Geophysics students.
6- Related Disciplines.

** Course Description:
Specially recently, the Electromagnetic Methods have gained more wide application spectrum in oil and gas exploration and production, mineral exploration, groundwater exploration and monitoring, Geothermal Prospection, Reservoir monitoring, geotechnical and environmental industries. Although it has widespread application spectrum, it is not generally understood well by the geoscientific community. As a result, it is underutilized, and in some cases, misused, as a technology.
There are various EM techniques, some are active (Using artificially created fields) while other are Passive (using natural fields). Each technique has an optimum depth range, which depends on the
resistivity environment, with some overlap between these different methods.
This training Program varies for applications in hydrocarbon, Groundwater, mineral or geothermal exploration and production. For example, for hydrocarbon exploration, more focus will be on the strength of EM to resolve resistive reservoirs and marine electromagnetics, while for geothermal exploration, more focus will be on detecting conductive reservoir anomalies and changes.
Electromagnetic techniques are important for hydrocarbon Exploration &Production Geoscientific teams because they can distinguish between oil and water saturated rock, responding directly to water-filled porosity as well as they act as a useful tool for Reservoir Monitoring…
The sensitivity of EM decreases slowly with depth, so they can often be applied when seismics fails. However, their real strength lies in their complementary use, along with seismic, either to improve the seismic velocity interpretation or to provide additional information such as the resistivity structure & the inferred porosities. For example, the Magnetotelluric (MT) technique has been used
for oil exploration in seismically difficult areas, including karst in east and SE Asia, and for sub-salt and sub carbonate exploration in the Mediterranean and Gulf of Mexico.
The future of electromagnetic measurements lies clearly in their combination with reflection seismics to better define fluid content. In addition, EM results can be used to constrain the interpretation of seismic velocities.

1.What could be the cause of vibration in a building!

2. Could this leads to a building failure
3. Most especially through a decking,and there is vibration when someone pass through or when through the corridor?
4.Could this be as a result of Beam Or Stress Or something not properly layer?
