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.

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).

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).

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).

Modeling hydrocarbon flow from kerogens in a hydrocarbon bearing formation. At least some of the illustrative embodiments are methods including modeling flow of hydrocarbons through a hydrocarbon bearing formation by: obtaining an indication of kerogen-wet porosity of kerogen within a portion of the formation; obtaining an indication of water-wet porosity within the portion of the formation; modeling hydrocarbon movement through the kerogen-wet porosity; and modeling hydrocarbon movement through the water-wet porosity.

Optimizing well planning scenarios. At least some of the illustrating embodiments include: receiving, by a computer system, a complex fracture model that estimates fractures in a subsurface target; applying the complex fracture model to a reservoir model that estimates geological features between the subsurface target and earth's surface; and determining an earth surface well site and a well path from the earth surface well site to the subsurface target based on the complex fracture model and the geological information, wherein the earth surface well site is offset from the subsurface target.

Methods are included that are useful in treating subterranean formations and, more particularly, to minimizing particulate migration over long intervals in subterranean well bores that may be horizontal, vertical, deviated, or otherwise nonlinear. In one embodiment, a method is presented comprising: providing a well bore comprising an open hole section of about 30 feet or more that comprises an open hole section with a filter cake neighboring at least a portion of a reservoir; allowing the integrity of at least a portion of the filter cake to become compromised; and treating at least a portion of the open hole section with a consolidating agent system in a single stage operation so as to at least partially reduce particulate migration in the open hole section.

A sand control screen assembly (170) is operably positionable within a wellbore (48). The sand control screen assembly (170) includes a base pipe (172) having at least one opening (176) and an internal flow path (174). A swellable material layer (182) is disposed exteriorly of the base pipe (172). A fluid collection subassembly (184) and a sensor (192) are disposed exteriorly of the swellable material layer (182). The fluid collection subassembly (184) is in fluid communication with the internal flow path (174). A filter medium (188) is disposed in a fluid path between the exterior of the sand control screen assembly (170) and the internal flow path (174). In response to contact with an activating fluid, radial expansion of the swellable material layer (182) causes at least a portion of the fluid collection subassembly (184) and the sensor (192) to be displaced toward a surface of the wellbore (48).
