geophone, incontact, bad signal: Dear Ahmed, Couple is a term used for being incontact with the ground. If a geophone was mistakenly placed and was not couple with the earth, it records a bad signal and more background noise. Thus a geophone needs to be coupled with the earth surface good....

Geophysics: Time-Depth, depth conversion, seismic line

depth conversion, seismic line, time depth: Dear Suresh, A depth map is prepared normally by considering a datum. In seismic such a datum is SRD from where the velocity is referred to a depth of a reflector. Thus you need an average velocity. The root mean squared function normally increases rapidly...

Geophysics: diameter of the earth's surface, diameter of the earth, usgs website

diameter of the earth, usgs website, spherical object: Dear Jose, Sorry for a late response actually I am very busy now a days. Hm! I read the article and got your point. I do not know exactly how did they assume a spherical object of 1,385km (dia) containing water. Apologies that I wouldn t be able to...

Geophysics: AVO, amplitude response, seismic amplitude interpretation

amplitude response, seismic amplitude interpretation, shear velocity: Dear Blessing, OK! The Far-Near is a difference stack. We assume that in a normal condition, the Far angle amplitude response is an effect caused by the shear velocity and densities (fluids). And the near offset stack is mainly an influence of rock velocities...

Geophysics: AVO: Fluid Angle, intercept, gradient

intercept, gradient, short answer: Dear Blessing, You need this equation: Fluid effect = Intercept * cos(angle) + Gradient * sin(angle) Lithology stack = - Intercept * sin(angle) + Gradient * cos(angle) Note: Both effects are orthogonal to each other. If you predict one, the...

Geophysics: Dix formula, depth maps, depth structure

depth maps, depth structure, time structure: Dear Haider, If the provided velocities are interval velocities, you need to convert them into average velocities from the datum. If the provided velocities are RMS then you need to convert them into interval velocities first using the Dix Interval Velocity...

Geophysics: Geophysics, operator length, kfupm

operator length, kfupm, deconvolution: Dear Dhanam, It is always been very difficult to predict the operator length. Autocorrelation method is normally used to predict the operator lenght: 1- Autocorrelation of the source signature - if it is known. 2- Autocorrelation of the seismic trace....

Geophysics: Geophysics, seismic wavefield, dense sampling

seismic wavefield, dense sampling, wave field: Dear Mazhar, It is not very simple to explain in a short answer. Conventionally we do not record a complete reflected wave field. To get a better image of the sub-surface, we could acquire wide-azimuth recording and sufficiently dense sampling to obtain...

Geophysics: Porosity, thin section, resolution limit

thin section, resolution limit, porosity: Dear Blessing, I will say thin section. But there is a pitfall in it as the wireline log suffer the resolution limit and the thin section measures ultra high resolution. So, the well porosity is actually the next porosity measurement whereas the thin section...

Geophysics: seismic project, seismic project, well logs

seismic project, well logs, routine job: Dear Dhannie, I guess you are thinking of a successful story that you would like to publish. Of course, what you need to think of is beyond your routine work. The fact is when you are doing the routine job you do not get time to think. The better way of...

Geophysics: Velocity Push-Up, river niger, high velocity

river niger, high velocity, dry well: Dear Suresh, Without seeing the data, it would be hard to explain this. Here is my thought! A possible case would be that the statistics might have not been applied with care. Second scenario would be that you used 2D data and didn t apply the right...

Geophysics: porosity estimation of carbonate reservoir using AVO attributes, hampson russell, seismic interpretation

hampson russell, seismic interpretation, porosity: Dear Researcher, Yes you can do the porosity prediction from the HR Software. For the carbonate reservoir AVO signature may vary because of dolomitization and cementation. You will have to establish the AVO character by studying the wells per field area....

Geophysics: Identification of lithologies

Dear Amjad, A first straight answer is NO! A flexible answer is yes, if you talk about an inverted seismic data. Due to inversion, you an characterize the seismic response being shale/sand. A seismic signal natively is a series of amplitudes nothing...

Geophysics: Petroleum Geophysicist

Dear Anthony, I think the best would be reservoir characterization as you can get into geophysical field quickly with this. Rest, I always say, Make your own choice and figure out what do you like the most than the rest. Try to think where your interest...

Geophysics: angle stacks

Dear Krishna, Here are the quick answers to your questions: 1- At first place, this varies with the depth of target interval. We can go normally up to 40-45 deg. of angle. However, you can choose a variation such that you create stacks after every 5-deg....

Geophysics: stacks

Hi Krishna, 1. A lithology stack is a stack based on theoretical knowledge. For instance, on an AVO plot, you can draw a background trend representing a lithology and call it a lithological trend. You can use such a trend to make a new stack and call it...

Geophysics: Geophysics, reservoir properties, seismic energy

reservoir properties, seismic energy, seismic wave: Dear Jeevan, When a seismic wave passes through Earth, some energy is lost by attenuation. This attenuation is generally quantified by Q. Note that there are two processes: intrinsic and extrinsic/scattering attenuation. The first one is considered t be...

Geophysics: Geophysics, water saturation, saturation levels

water saturation, saturation levels, acoustic impedance: Dear Kashif, I do not understand it fully but I believe you meant to generate a contour map. If so, you need to get a relationship between water-saturation and Acoustic impedance. Then apply that relationship on a volume or grid. Otherwise, I will suggest...

Geophysics: Seismic data processing, automatic gain control, time gate

automatic gain control, time gate, seismic data: Dear Shahbaz, Here are my answers: 1- AGC is applied to compensate the amplitude decay with depth. It is like boosting up the amplitude based on a time gate. It is a sliding window operation with an average amplitude scaler. Normally it is done with...

Geophysics: Geophysics-Amplitude spectrum, amplitude spectrum, signal amplitude

amplitude spectrum, signal amplitude, phase spectrum: Dear Jeevan, I hope the following concise answers explain your questions: 1) Power spectrum defines the power of a signal amplitude at frequencies whilst the amplitude spectrum defines signal amplitude at frequencies without taking its power. Amplitude...

Geophysics: Geophysics-well log correlation, trend surface analysis, relative geologic time

trend surface analysis, relative geologic time, amplitude spectrum: Dear Jeevan, I will go brief. 1) You need to clarify the objectives prior to correlation. This means that you need to know what type of correlation are you going to establish. Lithostratigraphic, chronostratigraphic, sequence stratigraphic or allostratigraphic....

Geophysics: Sample Interval Effect, 2ms, higher frequency

2ms, higher frequency, aoa: Dear Shahbaz, Yes! If you upscale the data from 2ms to 4ms, you shall expect to remove the details that were recorded at a finer scale. You should do it if the objective is to study the coarser information and the higher frequency information are mostly...

Geophysics: Defining SEG Polarity together with American and European Convention

Dear Nabila, This is always confusing and I wonder if you are stating it from my earlier answers or is this your own perception. The difference between the SEG and EU is -1. If SEG says +1 then EU says -1 for the same thing. Let us assume that we...

Geophysics: Earth`s formation

Dear Cole, To me, matter changes it form with time, pressure and temperature. If you see it like this, you may consider that a black hole with only a single form of energy should be sufficient to make various elements. The only problem is to recognize how...
