1) Rotary drilling uses a rotating drill bit attached to a string of drill pipe to bore holes into the earth for extracting oil, gas, water or other resources.
2) The normal drilling operation involves attaching the drilling apparatus into the hole, drilling to reach the preset depth, casing and cementing the hole, testing at the final preset depth, and completing the well.
3) Well completion establishes a conduit for resources to flow from the reservoir to the surface and includes perforating the casing near the reservoir, and installing a tubing, packers and valves to control flow.
Geological sample preparation is a vital stage in the analytical process, given the highly variable nature of mineral samples. The purpose of sample preparation is the production of homogeneous sub-sample, representative of the material submitted to the laboratory.
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

Room and Pillar mining method is one of the oldest existing mining methods. This system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. Usually those room and pillars are uniform size. Pillars may or may not be removed after extraction.
Used for soft as well as hard rock mining and is commonly associated with coal, potash, uranium, and other industrial materials.
Open pit mining is the process of mining a near surface deposit by means of a surface pit excavated using one or more horizontal benches.
The term open pit mining is usually used for metallic or non-metallic deposits and sparingly used for bedded deposits like coal.
The presentation comprises the Gravity Method, It's anomaly, reduction, and its applications. The Gravity method is commonly used in Geology specifically in Geophysics.

Adani SEBI investigation revealed that the latter had sought information from five foreign jurisdictions concerning the holdings of the firm’s foreign portfolio investors (FPIs) in relation to the alleged violations of the MPS Regulations. Nevertheless, the economic interest of the twelve FPIs based in tax haven jurisdictions still needs to be determined. The Adani Group firms classed these FPIs as public shareholders. According to Hindenburg, FPIs were used to get around regulatory standards.

Understanding User Needs and Satisfying ThemAggregage
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs

4. Normal Drilling Operation
In normal drilling operation, we simply divide
the process into several steps. That are :
The attachment of the drilling apparatus into
the hole.
The drilling process.
Casing and Cementing
The Final Preset Depth Test
Well Completion
5. The attachment of the drilling apparatus
into the hole
In this phase, the drilling crews place the drill
bit, the drill collar, and the drill pipe and then
attach it with kelly and put it on the turn
table, then we begin to drill the hole.
6. The Drilling Process
The drilling process refers to the drilling itself. In
this phase the drill bit will move in a rotary
motions and begin to cuts up the rock
formation. As the drilling progresses, the drilling
crews circulate the mud through the pipe in
order to push the rock cuttings out of the hole.
This will continue, until the preset depth is being
reached.
7. Casing and Cementing

8. The Final Preset Depth Test
Actually in drilling we will do such the same
thing repeatedly until we reach the final preset
depth. And when the final preset depth is
expected to be reached (usually known from the
rock cuttings), we do 3 kind of tests (may be
more) in order to ensure that that was the final
depth. The tests are: well logging, drill stem
testing, and core sampling
9. Well Logging
The purpose of this test is to take a
measurement of the rock formation there. And
in well logging, we knew several methods such
electrical logging, radioactive logging, mud
logging, and accoustic logging
10. Drill Stem Testing
The drill stem testing purpose is to measure the
pressure of the recent depth in the hole by using
such a device.
11. Core Sampling
Core sampling, don’t misunderstood this as mud
logging, they are DIFFERENT. In core sampling or
coring, you take the whole long formation from
the top into the reservoir using a pipe then you
analyzed it, not analyzing the rock cuttings that
is being delivered by the drilling mud.
12. After the test done and the results was positive
that it is the final depth, we start doing as what
we call for well completion, and this is the one
step we do before starting the production
phase.

14. Well Completion
After the perforation is done, we put the tubing
on the hole as a conduit for oil and gas to flow
up the well. The tubing is being hold by the
packers to form a seal around the outside of the
tubing, so it will be steady. Finally we put a
multivalve structure (the chrismast tree) at the
top of the tubing, the christmas tress allow us to
control the flow of the oil and also to make such
a great pressure difference between the surface
and the reservoir.
