8.Reconfirm screen out in upper gravel pack position after one hour, with 1500 psi at less than 1/2bbls/min pumprate. If satisfactory, POH otherwise inform base. 3 External gravel packing procedures. 1.With the liner set and the gravel pack tool in the circulating position establish circulation at 0.5-5 bbls/min.
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 the most widely used method of sand control in the oil industry, accounting for nearly 75% of all sand face treatments. During gravel pack operations, a …
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 …

Summary. Technological advancement in horizontal drilling and openhole completing techniques for soft-rock formations finally has bridged the gap between the drilling and completion disciplines. The success achieved with openhole gravel packing has created a mainstay completion technique that has been used in deepwater …
Halliburton has been awarded an international license for ExxonMobil's patented Non-Aqueous Fluid Gravel Packing (NAFPac) technique for gravel pack completions. Hole stability and shale inhibition are keys to successful installation of open hole completions. Non-aqueous fluid (NAF) is often selected to optimize the drilling …
During gravel placement, the shale can intermix with the gravel-pack sand, resulting in reduced gravel permeability and impaired well performance. Again, proper drill-in fluid selection can alleviate some of the problems associated with laminated sand and shale formations. Openhole gravel-pack candidates include:
Pump rates are higher than for conventional gravel packing but usually lower than a frac pack. Typical pump rates are in the range of 8 to 12 bbl/min. Proppant loading is held constant between 1 and 2 lbm/gal, and total job size is …

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 …
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 …
