摘要： An apparatus (38) and method for progressively gravel packing an interval of a wellbore (32) is disclosed. The apparatus (38) comprises a sand control screen (52) that is positioned within the wellbore (32) and a tubular member (42) that is disposed within the wellbore (32) forming a first annulus (56) with the sand control screen (52) and a second annulus (58) with the wellbore (32). The tubular member (42) initially prevents fluid communication between the first annulus (56) and the second annulus (58). Once the gravel packing operation begins, however, the tubular member (42) selectively allows fluid communication from the first annulus (56) to the second annulus (58) by progressively establishing fluid communication between the first annulus (56) and the second annulus (58) from a first end of the interval (48) to a second end of the interval (48).

摘要： A screen assembly (38) and method for progressively treating an interval (48) of a wellbore (32) is disclosed. The screen assembly (38) comprises a sand control screen (40) that is positioned within the wellbore (32) and a plurality of diverter members (42) that are positioned along the sand control screen (40). During a treatment process when a treatment fluid is pumped into the interior of the sand control screen (40), the diverter members (42) progressively allow the treatment fluid to exit from the interior of the sand control screen (40) to the exterior of the sand control screen (40) from a first end (46) of the interval (48) to a second end (44) of the interval (48) to progressively treat the interval (48) of the wellbore (32).

摘要： An apparatus and method for progressively treating an interval of a wellbore (32) is disclosed. The apparatus comprises a sand control screen (138) that is eccentrically positioned within the wellbore (32) and a fluid delivery tubular (140) that is disposed within the wellbore (32) adjacent to the sand control screen (138). During a treatment process when a treatment fluid is pumped into the fluid delivery tubular (140), the fluid delivery tubular (140) progressively allows the treatment fluid to exit from the interior of the fluid delivery tubular (140) to the exterior of the fluid delivery tubular (140) from a first end (46) of the interval (48) to a second end (44) of the interval (48) to progressively treat the interval (48) of the wellbore (32).

摘要： Screen assemblies (40, 42) and a single trip method for selectively fracturing multiple formations (14, 16) traversed by a wellbore (32) are disclosed. Each formation (14, 16) has a screen assembly (40, 42) having a plurality of valves (60, 66) positioned adjacent thereto. During the treatment process, the formations (14, 16) are selectively treated with a treatment fluid that is pumped into the interior of the adjacent screen assembly (40, 42). The valves (60, 66) of the respective screen assemblies (40, 42) progressively allow the treatment fluid to exit from the interior to the exterior of the screen assemblies (40, 42) such that each formation (14, 16) is progressively fractured.

摘要： A position-indicating tool includes an outer mandrel that accommodates two or more indicator lugs movable between a first position, where the indicator lugs extend past an outer diameter of the outer mandrel, and a second position, where indicator lugs are radially contracted within the outer diameter, an inner mandrel arranged at least partially within the outer mandrel and providing a radial protrusion that radially supports the indicator lugs in the first position, and a pressure block arranged between the outer and inner mandrels to control a flow of hydraulic fluid between an upper hydraulic chamber and a lower hydraulic chamber, wherein, when a pressure threshold is exceeded in the lower hydraulic chamber, the hydraulic fluid is able to flow into the upper hydraulic chamber and thereby allow the outer mandrel to axially translate with respect to the inner mandrel and move the indicator lugs to the second position.
