Comparative study of performance between Positive Displacement Motor (PDM) and Rotary Steerable System (RSS).

Abstract

Directional drilling is a precise and efficient technique used in the hydrocarbon industry to extract natural resources from beneath the Earth's surface. It involves drilling at specific angles using advanced equipment to reach targeted layers accurately. By controlling the drill bit's direction, directional drilling optimizes the utilization of oil and gas fields, reduces the need for multiple wells, and minimizes environmental impact while lowering production costs. This technology has been extensively employed in the Ouargla region of Algeria, a prominent oil-producing area. By employing directional drilling, operators can access previously inaccessible reservoirs, resulting in enhanced reservoir contact, increased production rates, and improved overall well performance. Two notable drilling technologies, Rotary Steerable Systems (RSS) and Positive Displacement Motors (PDM), further enhance drilling efficiency and accuracy in directional drilling operations by precisely steering the drill bit to the desired target zone. In our study, we conducted an analysis of Bottom Hole Assemblies and their types, as well as an analysis of Rotary Steerable Systems and Positive Displacement Motors. We compared their performance to determine the advantages of each system in order to make the best choice for a drilling program.
