Summary. Cased-hole gravel packing is commonly used to control sand production from oil and gas wells. The success of a cased-hole gravel-pack job depends on the ability to effectively pack perforation tunnels, which act as conduits between the reservoir and the wellbore for hydrocarbon production.This project presents a systematic …

Abstract High angle, openhole completions are often selected to maximize production and reserve capture from several non-homogeneous sand packages in a single wellbore. Many times, the wells will require some form of sand control. Standalone screen applications may often times be the most cost effective and simplest form of sand control, but the …

Even techniques that are not widely used may have a potential application in which its use might be superior to others. Gravel packing is currently the most widely used technique. The cost to gravel pack is directly related to rig costs. Gravel-packed completions from floating drilling rigs may cost in excess of US $2 million.
Gravel packing is a well completion technique used to prevent the production of formation sand in oil and gas wells. The technique involves placing a packed screen and/or a pre-packed screen in the wellbore. A sand-sized (typically 0.020-0.08) filter media, usually gravel, is then placed around the screen to form a sand-free annulus …
The productivity of a gravel-packed well depends on the permeability of the gravel-pack sand and how it is placed. To ensure maximum well productivity, one should use high quality gravel-pack sand. API RP 58, Testing Sand Used in Gravel Packing Operations, establishes rigid specifications for acceptable properties of sands used for …

Gravel packing is a mechanical means of controlling sand production. If properly designed and applied, this completion technique can provide adequate sand control throughout the life of a well. To obtain an effective gravel-packed completion, it is essential that the pack be properly designed using the proper gravel, screen, carrier …
The largest amounts of, and the least weathered, oil found eight years after the Exxon Valdez oil spill occurred at depths of 25–50+ cm under the protective cover of a well-sorted cobble/boulder armor on intermittently exposed, coarse-grained gravel beaches within Prince William Sound, Alaska. In addition to the armoring, other factors enhancing …

Abstract. In recent years, it has become common practice for operating companies to make a significant effort in the planning of gravel pack installations, especially in their most important wells. Typically, the placement of the gravel pack is accurately modelled, and multiple contingencies developed for potential alternative …
