Scale problems in production - PetroWiki

 · Wells producing water are likely to develop deposits of inorganic scales. Scales can and do coat perforations, casing, production tubulars, valves, pumps, and downhole completion equipment, such as safety equipment and gas lift mandrels. If allowed to proceed, this scaling will limit production, eventually requiring abandonment of the well.

Double-Contrast Barium Enema - an overview

Double-contrast barium enemas (DCBEs) have a sensitivity of 50% to 80% for polyps less than 1 cm and of 70% to 90% for polyps greater than 1 cm. Because it allows visualization of the remaining colon, it has been a useful adjunct to sigmoidoscopy. DCBEs and flexible sigmoidoscopy have been demonstrated to have a 98% sensitivity for carcinomas.
