From 2012, ExxonMobil GmBH planned to drill several technically challenging, horizontal wells to access tight gas reserves in the Straßfurt Carbonates. Baker held the drilling contract and after review refused to attempt this program as they believed their technology could not meet ExxonMobil’s objectives. Schlumberger believed that with our technology, people, drilling practices and experience that we would be a good partner to drill these wells and meet the objectives.
The two initial wells, Goldenstedt Z-21 and Z-25, would be drilled in tough, abrasive conditions with the
expectation of total loss of circulation in the faulted and fractured zones. Mature technologies such as the PowerDrive Xtra, MicroScope, PeriScope and AdnVISION services were used to proactively geosteer and fully characterize this unpredictable reservoir.
Every individual bespoke BHA was extensively engineered by D&M Drilling Engineering, utilizing i-DRILL,
IDEAS and DOX for specific applications and challenges identified during the offset analysis stage. The
BHA’s were designed for the high-friction formations and tailored to reduce the excessive Shock & Vibration, stick-slip, differential sticking, H2S and total losses through faulted and fractured zones. Given these factors, Smith consulted the Z-25 Drilling Engineering team to design a bit to be suited and used. Show less

Bati Raman is a well developed reservoir in SE Turkey with over 400 wells (almost all vertical).

Bati Raman is a well developed reservoir in SE Turkey with over 400 wells (almost all vertical).
Area has heavy oil (12-13 API) and various EOR techniques are being used to increase the production.
One idea to improve the production is to drill horizontal wells and have bigger exposure in the reservoir
layer. However, production pumps are limited to operate in maximum 10 degrees inclination which
place them above KOP. Combined with low reservoir pressure and low static fluid level, efficiency of the
horizontal well does not reach desired level.
Solution to the problem was found in using twin wells: One vertical well is drilled for accommodating the pump below the reservoir level and horizontal well is drilled to intersect the vertical
well to provide drainage section. Show less

industry to put focus on the development of
more complex reservoir targets and drilling
profiles. The actual recent history of offshore
drilling in Libya is marked by a recurrent increase of difficulties to complete the data acquisition, associated increases in costs with
additional rig time and drilling risks.
Challenges:
When REMSA planned to drill concession
NC202 they faced several challenges:
HP/HT: A1-NC202 well was planned to TD at
a depth of 15900 ft and estimation for static
temperature was over 350 F.
HSE: due to local regulations and high risk of
getting stuck, any radioactive material was
banned from the logging program.
Real Time Data: High drilling risk and hole stability issue that could result in a loss of data, as
well as real time interpretation and decision
making capabilities put the Real Time delivery
at the top of the priority list.
Reservoir Characterization: To be able to
evaluate a new reservoir, in carbonates
Schlumberger focused on delivering the best
quality most complete set of logs to achieve the
goal.
EcoScope was proposed to provide a complete
petrophysical evaluation logging capability, by
being able to provide Density without natural
radioactive source, in recorded mode as well as
in real time. This unique logging tool was able
to perform the logging in A1-NC202 and evaluate the main target reservoir section Show less

Schlumberger Libya has seen considerable change in the past 12 months, in terms of Activity and the level of service expected. In Q4 2008, there was a clear step change in activity, moving from what was a traditionally land orientated operation to an offshore exploration GeoMarket with all the expectations that go with this. The number of LWD jobs increased by 300% in 6 months. The focus changed again in February 2009, when ExxonMobil brought forward their Deepwater exploration plan by 6months, with the intention of spudding by 1st May 2009. This left Schlumberger Libya with just 3 months to prepare and deliver a fully operating Deepwater Service out its supply and maintenance base in Tripoli. Any Deepwater project is high profile, with high cost and consequentially high risk. The additional focus that ExxonMobil expects and demands for the very highest standards required a global coordinated approach by Schlumberger. Show less

The application of the periscope at that time would have been to steer the well at the top

landing the well on the other side of the fault and identify the top of the reservoir.
The modeling study show that Periscope was performing as expected and would have
been able to achieve these objectives.
Even more, the study shows that periscope would have been able to steer the well at the
top of the reservoir along the whole section of the well.
In that case Periscope would have minimized the drilling hazards, especially when crossing the fault. It would also have maximized the production and recovery by maintaining the well in the upper part of the reservoir, far away from the water and reducing drastically the attic oil. Show less

Both sections were drilled flawlessly with excellent data quality. The well placement team were able to use the PeriScope information to remain in the reservoir despite the thin target zone. The entire Scope suite were able to identify faults and determine if they compartmentalized the reservoir, adding significant value to the well. Show less

In 2006, NGA had suffered from 1 CAT BHA twist off and five thread cracks for the same Non-Mag crossover sub between ARC8* and Powerpulse* (5-1/2” IF Pin x 6-5/8” FH Pin) which had serious impact on D&M reputation where a client like ExxonMobil refused to reuse the service unless they understand the root causes, close to $500K of red money losses in 2006 and serious concerns about the yield strength for that particular sub. NGA service delivery team proactively started the analysis using SLB-SCAT process to identify the root causes with the support of LWD sustaining team. The project had significant successes from redesigning the sub after calculating all the stress computations locally using DRILCO software program (Torsional yields, DS-1 CAT 3-5, BSR etc.) taking into considerations the impact on internal components such as extenders, future machinability and the make up torques applied on the rig site. NGA proactively field tested (more than 500 operating hours with 100% success rate) the new sub after the fabrication of four prototypes. The project triggered two global changes for sub redesign including material change to P550 (from the original P530), torque specifications and a transition plan to replace all existing old design subs in the field. A worldwide notification is expected to be issued in a Tech Alert for other locations to replace the old designed crossover subs (Number of subs in NGA only is more than 50 pcs). Show less
