Fluids are key in drilling highly deviated wells (Journal ...

Abstract. Many problems in drilling highly deviated wells can be related to the drilling mud. Poor hole cleaning, excessive torque, drag and hole fill, stuck pipe, well bore instability, loss of circulation, formation damage, poor cement jobs, and difficulties running wireline logs are among the problems that can result if a mud job is executed poorly.

Sand control on a horizontal well is completely different from a vertical well. We can no longer rely on the gravity for the gravel placement. Most service companies uses an alpha and beta wave design to cover the total length of the horizontal well with gravel.

Better Design and Control of Deviated and Horizontal Wells ...

Our industry now finds itself in the era of horizontal wells and massive frac jobs. Horizontal wells are deviated before they reach the horizontal. Our industry needs downhole measurements in deviated wells that serve the same purposes that the 1990s measurements served for vertical or near vertical wells.

Abstract. Key factors in the efficient removal of sand fill from deviated wells are the proper selection of a fluid and the pump rates. The operation should be designed to (1) reduce or eliminate the formation of beds of particles in the annulus between the casing and tubing, (2) maintain the particles in suspension and (3) transport the fill to the surface.

Well types - AAPG Wiki

Horizontal wells are drilled in a specific configuration. The tangent section of the well is drilled along a deviated well path to just above the reservoir section, to what is known as the kick off point. From the kick off point, the well is drilled at an increasingly higher angle, arcing around toward an angle close to horizontal.
