| 139 | Sintered metal substitute for prepack screen aggregate | US23823 | 1993-02-23 | US5293935A | 1994-03-15 | Bryant A. Arterbury; James E. Spangler |
| A prepack well screen assembly has a resistance welded outer screen concentrically mounted in radially spaced relation on a perforated mandrel, thereby defining an annulus in which a sintered metal prepack sleeve is loaded. The longitudinal spacing distance between adjacent turns of the outer screen selectively exclude sand fines of a predetermined minimum size. The porosity of the sintered metal prepack sleeve is selected to pass sand fines in the size range of from about 10 microns to about 150 microns. The effective inlet flow area through the sintered metal prepack sleeve is substantially greater than the effective inlet flow area through the outer screen. The sintered metal prepack screen excludes sand fines from inflowing formation fluid during the initial production phase following a gravel pack operation, without limiting production of formation fluid. | ||||||
| 140 | Sintered metal sand screen | US601271 | 1990-10-22 | US5088554A | 1992-02-18 | Bryant A. Arterbury; James E. Spangler |
| A tubular sand screen is made in one piece entirely of powdered metal slivers which are molded and sintered to form a metallurgically integral rigid tubular structure. Aggregate metal particles, for example, stainless steel slivers, are bonded together by interatomic diffusion as a result of sintering the compacted slivers under high temperature and pressure conditions. The sintered metal sand screen performs the function of the conventional prepack assembly as well as the screen function. In one aspect of the invention, the sintered metal screen is subjected to electropolishing to yield an effective porosity of 40-60 mesh, with an average pore size of 150 microns. Most of the surface irregularities are removed by electropolishing, and very few nucleation sites remain where particles in the size range of 74 microns-100 microns can become captured or otherwise lodged to cause plugging of the screen. | ||||||
