Wired Drill Pipe for Petrophysics – What’s in it for me?
Date: April 13th 2016
As well construction process takes place, the cost per day for such operations are significant and can have a great impact for the final overall project economics. It is also of great importance of the subsurface data gathering and analysis. With the enchantments observed in regards of LWD technology, it has become of great importance not on the type but speed of the information acquired in Real time. Beyond the obvious benefits related to flat times reduction (Telemetry time), this presentation aims to provide an update of the Wired pipe Technology and ways to benefits from the bandwidth available in real time.

With WDP systems all downhole MWD and LWD data is been sent uphole to surface in real time despite the lack of mud flow, in other words the data transmission is continued independent of the mudflow. Some positive feedback from the use of the system has been:
- Unlimited memory quality data available (not limited by MWD tool memory capacity)
- Short space density image logs available in real time for Wellbore Stability Issues and fault identification.
- Higher data density results in higher quality RT LWD Logs.
- Gamma Ray images in real time with sufficient quality to recognize faults (and some borehole breakouts).
- Improved image quality increases confidence RT Dip picking service, and saving time as need for re-logging is eliminated.
- Potential for 120 sector RT Hi definition resistivity image in WBM.
- No loss of data even if LWD tools are lost downhole
- Able to determine borehole quality in and around cement plug, and confirm when bit is sidetracked in to new formation.
- Improved diagnostics capabilities from both RSS and MWD/LWD tools.
- Wired pipe provides increased data density meaning that images acquired at relatively high bit velocity (180 ft/hr) are still sufficiently good to provide invaluable information in regards of wellbore integrity/stability.
- High speed formation pressure acquisition - in one well drilled Deepwater GOM, a total of 54 formation pressure stations were conducted at 7 minute intervals per test.
- Opportunity to have complete petrophysical analysis performed on RM quality data when the well is at TD, i.e. no waiting for POOH, then RM data memory data extraction.
In summary there are many tangible benefits for subsurface groups from WDP data. Examples will be shown where the data has been released.
Jesus graduated from Monterrey Tech in late 1996 and obtained a Bachelor’s of Science of Mechanical and Electrical Engineering. He has over 18 years of experience in the industry, most of which relate to the well construction process. His career started as MWD/LWD/DD operator with Schlumberger and eventually held some management roles. Late in 2008, he became Director of Operations for NOV IntelliServ and managed several installations over the years. Early in 2015, he started as Business Development manager for IntelliServ. His experience in well construction process include the regions of US Land, Gulf of Mexico, Latin America, North Sea and North Africa.
