A positive Bouguer anomaly indicates extra mass below the surface, while a negative Bouguer anomaly indicates missing mass. The depth to the top of a gravity source can be estimated from the half-width of the anomaly. Gravity interpretations are non-unique, as different combinations of object geometry, depth, and density contrast can produce the same anomaly.

Introduction
Petrophysic of the rocks
It is the study of the physical and chemical properties of the rocks related to the pores and fluid distribution
Porosity, is ratio between volume of void to the total voids of the rock.
Permeability, is ability of a porous material to allow fluids to pass through it.
Electric, most of the sedimentary rocks don’t have conductivity.
Radiation, clay rocks have 40K, radiate alpha ray.
Hardness, it depends on the cementing material and thickness of the sediments.
WELL LOGGING
The systematic recording of rock properties and it’s fluid contents in wells being drilled or produced to obtain various petrophysical parameters and characteristics of down hole sequences (G.E Archie 1950).
The measurement versus depth or time, or both, of one or more physical properties in a well.
These methods are particularly good when surface outcrops are not available, but a direct sample of the rock is needed to be sure of the lithology.
A wide range of physical parameters can be measured.
In some cases, the measurements are not direct, it require interpretation by analogy or by correlating values between two or more logs run in the same hole.
Provide information on lithology, boundaries of formations and stratigraphic correlation.
Determine Porosity, Permeability, water, oil and gas saturation.
Reservoir modeling and Structural studies… etc.
Types of Well Logging
Logs can be classified into several types under different category
Permeability and lithology Logs
Gamma Ray log
Self Potential [SP] log
Caliber log
Porosity Logs
Density log
Sonic log
Neutron log
Electrical Logs
Resistivity Log

2 d and 3d land seismic data acquisition and seismic data processingAli Mahroug
The seismic method has three important/principal applications
a. Delineation of near-surface geology for engineering studies, and coal and mineral
exploration within a depth of up to 1km: the seismic method applied to the near –
surface studies is known as engineering seismology.
b. Hydrocarbon exploration and development within a depth of up to 10 km: seismic
method applied to the exploration and development of oil and gas fields is known
as exploration seismology.
c. Investigation of the earth’s crustal structure within a depth of up to 100 km: the
seismic method applies to the crustal and earthquake studies is known as
earthquake seismology.
A photon is a self-sustaining, electromagnetic traveling spin wave disturbance in a polarizable vacuum. A photon is described as a spin 1 boson with helical geometry. A graviton represents a momentary resonance superposition of a photon and counter-propagating phase conjugate photon with net zero linear momentum. A graviton is described as a spin 2 boson with helicoid geometry with additive spins. Phase conjugation reflection occurs at EM wave front interference anti-nodes at Fresnel zone boundaries.
Einstein's General Theory of Relativity interpreted in terms of a polarizable quantum vacuum. Electromagnetic wavelength increase corresponds to apparent time dilation while a frequency increase corresponds to an apparent space contraction as a result of a spectral energy density gradient.
Einstein's General Theory of Relativity interpreted in terms of a polarizable quantum vacuum. Electromagnetic wavelength increase corresponds to apparent time dilation while a frequency increase corresponds to an apparent space contraction as a result of a spectral energy density gradient. Matter in motion generates a de Broglie matter wave (contracted moving standing wave). An inverse effect of induced motion of matter by matter wave synthesis is predicted.

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
