The well-collision-avoidance management and principles presented in this paper are a
culmination of the work and consensus of industry experts from both operators and service …

Magnetic debris in a drilling fluid have a significant influence on the ability of the drilling fluid
to maintain its function. Down hole logging can suffer from poor signal to noise ratios …

Improving the Accuracy and Reliability of MWD/Magnetic-Wellbore-Directional Surveying in

Time-dependent current fluctuations in the Earth's ionosphere cause inaccuracies in
wellbore directional surveying. These inaccuracies increase at higher latitudes, and …

Different logging operations can suffer from presence of metallic particles in the drilling
fluids. Directional drilling in Arctic areas can be a challenge because of magnetic …

Magnetic shielding of the Measurement While Drilling (MWD) directional tools and damages
to mud pumps, down-hole tools and casing/drill-pipe and difficulties in understanding …

The complex process of anti-collision in directional well planning has gained particular
attention in the Alaska North Slope (ANS) as the economic and environmental constraints …

The auroral zone is the region surrounding the geomagnetic North and South Poles, and it is
where the largest and most frequent disturbances in the Earth's magnetic field are …

Positioning and Position Error of Petroleum Wells We present a new model for the
estimation of positional uncertainty of petroleum wells. The model uses a heavy tailed …

The magnitudes of certain significant error terms vary with latitude, for both magnetic and
gyroscopic surveying instruments. This implies an increase in surveyed azimuth uncertainty …
