(4,248 meters), bringing total footage drilled to 8,662 feet (2,640

meters) with zero NP.

o drill and log through the HP/H reservoir in the 8 -inch hole,Halliburton used a SOLAR Geo-Pilot XL system with a full suite of

SOLAR LWD tools including gamma, resistivity, density, bi-modal

acoustic sonic (BA) and neutron porosity sensors. Te SOLAR

suite made it possible to assess and characterize the quality of the

reservoir, identify perforation intervals and assist in correlation and

casing point selection, while providing better understanding of the

field. Te 8 -inch section was treated with BARACARB bridging

agent and SEELSEAL lost circulation material incorporated into

the drilling fluid to seal microfractures and help strengthen the

formation during drilling operations.

With all LWD sensors working perfectly in both real-time and

memory modes, the SOLAR Geo-Pilot BHA with SOLAR LWD quad

combo delivered the entire 2,323-foot (708-meter) section in a single

run, intersecting all geological targets with zero NP. In what was the

fourth longest section in the UK for drilling hours on bottom since

records began, the SOLAR LWD quad combo was down hole for

355.25 hrs (14.8 days) with the telemetry pulser functioning flawlessly

for 296 circulating hrs (12.3 days). Successful LWD performance

eliminated the need for wireline logging, and the well reached total

depth at 16,232 feet (4,948 meters) 25 days ahead of plan.

ECONOMIC VALUE CREATED Halliburton executed the

Drilling Performance solution and delivered the well 25 days ahead of

plan. Assuming an approximate rig rate of $250k per day, Halliburtons

performance resulted in economic savings to the customer of

approximately $2 million. In addition, successful acquisition of a full

suite of LWD logs eliminated the need to perform wireline logging

a first for the operator in this North Sea reservoir.
