Maintains safe and economically optimized drilling performance.
 |
Technical data acquisition is aimed to: - Control the compliance of current drilling with planned one; - Early detection of oil and gas shows and circulation loss; - Optimize the well deepening depending on geological problems; - Recognize and determine the technological operation duration; - Select and maintain the suitable drilling regime and control drill bit lifetime; - Early detection of shows and fluid absorption, manage filling-up operations; - Optimize RIH/POOH operations (limit running speed, calculation of equivalent mud weight, etc.); |
- Control bottomhole pressure;
- Control formation pressure and predict zones with abnormally high and low pressures;
- Manage casing and cementing works;
- Real-time identification of pre-emergency situations;
- Manage the current type of work at the well site: drilling, circulation, reaming (gauging), well logging, etc.
The following technical parameters are measured while drilling:
|
Wh. – Weight on hook |
Рвх. –Manifold pressure |
|
Ns. – Strokes amount |
Nr. –Rotary per minute |
|
Mrot. – Rotary torque |
Qout. –Flow out |
|
Qin. – Flow in |
Нtb. –Travelling block location |
|
Vmud. – Mud levels in mud pit |
Mud conductivity flow in and out of well |
|
Тin. – Flow-in mud temperature of well |
Тout. – Flow-out mud temperature |
|
Mud weight flow in and out of well |
Т – Drilling time |
We receive the following technical parameters after data processing by logging unit software:
|

|
Average ROP |
Round trip speed |
|
Weight on bit |
