4. Introduction MWD
What is MWD?
Resistivity, natural gamma ray, porosity
wellbore geometry (inclination, azimuth),
Mechanical System

5. MWD Components
There are few components:
1. Telemetry channel
2. Transmission system
3. Power source
4. MWD sensors
5. Surface system

8. MWD Telemetry Process
• Telemetry is the process of transmitting data
from one place to another
• The process includes:
1. Down hole measurements
2. Data conversion
3. Signal generation
4. Signal propagation
5. Surface sensor acquisition
6. Signal demodulation

9. Surface Systems
• The purpose is to collect and process data about
drilling parameters and geological information
about formation.
• Surface system is composed of five main parts:
1. Sensors (Signal Pressure Transducer, Rotary Torque Sensor)
2. Sensor peripherals
3. Computers
4. Logging units
5. Peripheral components
9

10. Way Forward
• Sonic logging while drilling
• The expanding role of mud logging
• A hybrid rotary steerable system
• Shale gas: a global resource

11. PLC (Programmable Logic Control)
11
sebuah peralatan elektronik digital yang menggunakan memori
pemrograman untuk penyimpanan internal instruksi yang
berguna melaksanakan fungsi-fungsi spesifik seperti logika,
urutan, waktu, menghitung dan aritmatika untuk mengontrol
mesin-mesin dan proses-proses dalam suatu pengendalian
(controller) melalui modul digital atau analog, komputer, dan
berbagai jenis mesin atau proses, serta bahasa pemrograman.

14. Distributed Control System
14
DCS merupakan
sistem kontrol yang
mampu menghimpun
(mengakuisisi) data
dari lapangan dan
memutuskan akan
diapakan data
tersebut, secara
singkat DCS ->
ambil/baca data +
lakukan pengontrolan
berdasar data
tersebut.

17. Microprocessor
The uP is the ‘brain of the microcomputer’ Is a single chip which is
capable of
• –processing data
• –controlling all of the components which make up the
microcomputer system
• μP used to sequence executions of instructions that is in memory
• uP Fetch , Decode , and Execute the instruction
• The internal architecture of the microprocessor is complex.
• Microprocessor (MPU) typically contains
– Registers: Temporary storage locations for program instruction or
data.
– The Arithmetic Logic unit (ALU): This part of the MPU performs
both
arithmetic and logical operations
– Timing and Control Circuits: that keep all of the other parts of
system
(Regs, ALU, memory & I/O) working together in the right time
sequence. 17
