MICRO DOGLEG DETECTION WITH CONTINUOUS INCLINATION MEASUREMENTS AND ADVANCED BHA MODELING
Micro doglegs are a natural effect of any vertical or directional well that can explain a wide variety of down hole problems, from additional torque and drag to an inability to run completions.

SYSTEMATIC FIELD VALIDATION OF NEW CASING WEAR QUANTIFICATION PROCESS
To properly derive the wear from simulated mechanical work, a 3-D oriented wear model is used. This 3D mesh is able to distinguish the influence of different contact geometries on the wear groove shape and the location of thinnest

MITIGATING AND UNDERSTANDING STICK-SLIP IN UNCONVENTIONAL WELLS
Stick-slip is still present in most of the wells drilled today, especially in unconventional wells. Friction is an inevitable and important force along the long lateral section, but it contributes to many types of dysfunctions that lead

USING ALUMINUM DRILL PIPE WITH AXIAL OSCILLATION TOOLS TO SIGNIFICANTLY IMPROVE DRILLING PERFORMANCE
Aluminum drill pipe has already been proven as a viable alternative to steel drill pipe when drilling long horizontal wells thanks to its lighter weight that does not compromise resistance to yield.
