Types of curves in Vertical Electrical Sounding In Vertical Electrical Sounding, there are basically 4 types of curves but in real situations in the field, we usually encounter situations where these curves are merged to form a compound curve. ρ1 < ρ2 > ρ3      …...     K-type curve   (maximum type) Do you know the difference between schlumberger array and wenner?   ρ1 > ρ2 < ρ3      ……   H-type curve   (minimum type) ρ1 > ρ2 > ρ3      ……   Q-type curve (descending type) ρ1 < ρ2 < ρ3      ……   A-type curve   (ascending type) Some compound curves: ρ1 < ρ2 > ρ3< ρ4      ------ KH type ρ1 > ρ2 < ρ3> ρ4   ----- HK type

COMPARISON   BETWEEN SCHLUMBERGER ARRAY OVER WENNER ARRAY Find below the pros and cons of Schlumberger Array over Wenner Array and vice versa Are you a young geologist? Click HERE NOW!!! Advantages of using Schlumberger Array over Wenner                 It requires less manpower and time than Wenner soundings.                 It is less sensitive to lateral variations in resistivity. The potential electrodes are moved only occasionally; In a Wenner sounding the potential and the current electrodes are always moved after each measurement. It is faster in field operation. Types of VES Curves Requires less physical movement of electrodes than the normal Wenner array because only the current electrodes must be moved between readings. The effects of near surface, lateral inhomogeneities are less on Schlumberger measurements when compared to Wenner measurements. In industrial areas, stray currents and telluric currents that a

Have you heard of Vasquez Rock? Credit: The above picture will be alien except to those within the vicinity of Aqua Dulce, California or perhaps, those that have visited here at one time or the other. Just watch the arcs and the angles formed by this deposit!! In case you do not know, the image you are seeing is Vasquez Rocks. Am fascinated about the arcs and the acute angles formed by this deposit.. Your groundwater may be polluted!!! Nature is indeed wonderful!!!! For emphasis sake, this is in Aqua Dulce, California, north of Los Angeles. Research has it that the ‘arcs’ formed (i.e. tilting was as a result of the North American Plate collision with the Pacific Plate) along the San Andreas fault. We can see that the collision resulted in the uplift.

Are you an undergraduate studying geology in any tertiary institution and bothered about what may become of you after graduation? Are you yet to enter the university perhaps to study geology but seems you do not know what and what you may be at the instance of your graduation? The truth is … you are in the right place. That is why you landed on this page!!! Be that as it may, Geology is the study of the history (and present) of the Earth. We will not delve much into this definition now. A geologist is one that studied geology. Are you a young Geologist and you want to know the problems usually encountered by them? The main aim of our discussion here is to throw light on the opportunities prevalent as a geologist. They include: Hydrogeologist / hydrologist Geochemist Geophysicist / seismologist Mudlogger Geoscientist Wellsite geologist Do you know the apparent resistivities of common rocks?? Economic geolo

See credit here :: Add caption See credit here :: I was browsing and came across this. So I decided to share it to my readers. Happy reading!!! This outcrop is the  geologic type section  for the  Qusaiba Member , which is a primary  source rock  for the world's largest  oil field  ( Ghawar ). The  organic-rich shale  of the  Lower Silurian  Qusaiba Member, of the  Qalibah Formation , is one of the most prolific source rocks on the planet. It provides more than 90 percent of the  Paleozoic   light oil  and gas accumulations known on the Arabian Peninsula.

Hey dear reader… How are you? I will be sharing this piece with you because you are on this blog. Wait a minute!!! How much do you know about arrays? Are you a geologist? Are you passionate and want to delve into geology or it’s related fields?
