Sun Unveils Next Steps in its Vision of “The Network is the Computer”
Three newly unveiled while-drilling products from Schlumberger set new standards for reliability and data quality, while quadrupling the data transmission rate over the industry standard.
EcoScope, StethoScope and TeleScope comprise the Scope family of new-generation drilling services – extensively field tested and proven to improve drilling performance and well placement to increase production sooner.
 EcoScope:
Multilogging while-drilling, delivers industry first measurements, faster.
StethoScope:
Formation pressure while-drilling, improves efficiency and reduces risk.
TeleScope:
High-speed telemetry while-drilling, transmits more data, faster.
“The Scope series of products represent a step-change in real-time logging-while-drilling and measurements-while-drilling technology that provides the operator greater efficiency, reliability and help to better manage risk,” said Paal Kibsgaard, President, Schlumberger Drilling & Measurements, speaking at the recent launch of Scope at the 2005 SPE/IADC Drilling Conference in Amsterdam.
“Innovative products and services such as Scope keep Schlumberger on the forefront of drilling measurement technologies.”
The EcoScope multifunctional LWD service integrates drilling and formation evaluation sensors in a compact collar to deliver industry first measurements from a while-drilling service. EcoScope provides more downhole information from a single collar than any other LWD tool. Drilling and formation evaluation sensors are integrated into one collar to increase efficiency and safety. The EcoScope service replaces the traditional AmBe source with a pulsed neutron generator.
In wells from vertical to horizontal, StethoScope services provide formation pressures, fluid typing and mobility while-drilling, “helping the driller to optimize mud weight for better drilling performance and improving borehole placement for optimal productivity,” said Andy Hendricks, Marketing Manager, Schlumberger Drilling & Measurements.
StetheScope has already proven to be a key technology, helping Statoil in both exploration and field development programs. The Norwegian operator recently used the StetheScope service in its Kristin Gullfaks fields, among others, enabling early production and saving significant rig time.
“Its flexibility allowed us to run it successfully in a variety of downhole environments including vertical to high-angle deviations, high temperature/high pressure wells, as well as in formations with both low and high mobility,” said Harald Laastad, Advisor, geo-operations and data acquisition, Statoil. “We see great opportunities for this key technology in Statoil, especially in the production drilling environment.”
In the North Sea, real-time StethoScope data in a high mobility reservoir helped Statoil place a high-angle sidetrack wellbore, saving over $1 million in rig time. Data telemetry has long since been the bottleneck in real-time bit to surface communications. The TeleScope high-speed telemetry while-drilling service, when used in conjunction with the Orion telemetry platform, increases data transmission rates fourfold, compared to the industry standard.
“Actual data rates are very much a function of borehole conditions – mud weight, depth and the like,” said Hendricks. “During recent work on a 15,000-ft. high mud weight well, conventional data rates were around 3 to 6 bits/second (bps), while TeleScope achieved an approximate fourfold increase in data transmission rate. The maximum rate achieved to date has been in excess of 40 bps, clearly setting a new standard for borehole telemetry.”
The information that TeleScope delivers to surface improves drilling efficiency, reduces risk, optimizes well placement and ultimately increases production and recovery by providing a comprehensive picture of the downhole environment through real-time measurements from multiple tools.
