Filed:

Dec 2, 2004

Appl. No.:

11/003804

Inventors:

Leldon M. Farabee - Houston TX, US

Assignee:

Halliburton Energy Services, Inc. - Duncan OK

International Classification:

E21B 43/26

US Classification:

1663082, 1662722, 1662727, 166271

Abstract:

The present invention is directed to a method of increasing hydrocarbon production in an existing well in a hydrocarbon reservoir. The method includes the steps of forming a substantially horizontal transverse fractured wellbore that intersects the existing well and injecting a fluid remote from the existing well so as to form a fluid front that sweeps the hydrocarbons into the horizontal transverse fractured wellbore. Successive fractures can be sealed to control propagation of the fluid front and delay infiltration of the fluid into the production.

US Classification:

1661775, 166281, 166284, 1663081

Abstract:

An example of a method includes providing a hydrajetting tool in a well bore in a formation; injecting a fluid through the tool into a first region of the formation at a velocity sufficient to form one or more perforation tunnels; maintaining the flow of fluid into the perforation tunnels at a pressure greater than the fracture closure pressure, so as to create one or more fractures in the first region; plugging at least partially the fractures with an isolation fluid; injecting a fluid through the hydrajetting tool into a second region of the formation at a velocity sufficient to form one or more perforation tunnels in the second region; and maintaining the flow of fluid into the perforation tunnels in the second region at a pressure greater than the fracture closure pressure, so as to create one or more fractures in the second region.

Abstract:

The present invention is directed to a method of isolating hydrajet stimulated zones from subsequent well operations. The method includes the step of drilling a wellbore into the subterranean formation of interest. Next, the wellbore may or may not be cased depending upon a number of factors including the nature and structure of the subterranean formation. Next, the casing, if one is installed, and wellbore are perforated using a high pressure fluid being ejected from a hydrajetting tool. A first zone of the subterranean formation is then fractured and stimulated. Next, the first zone is temporarily plugged or partially sealed by installing an isolation fluid into the wellbore adjacent to the one or more fractures and/or in the openings thereof, so that subsequent zones can be fractured and additional well operations can be performed.

International Classification:

US Classification:

166/358000, 175/038000

Abstract:

Methods and apparatus for drilling subsea wells in deep water using dual-gradient drilling techniques. One preferred embodiment includes a high pressure riser running from a drilling platform at the surface to the seafloor. The base of the riser is connected to a wellhead that is anchored to the seafloor. Pressure control equipment is disposed on the upper end of the riser at the drilling platform. A coiled tubing drill string is run through the riser and into the subsea formation. The drill string preferably includes a pressure sensing device that can be used in transmitting real-time downhole pressure data to the surface. A riser injection system is provided to inject a lower density fluid into the riser annulus in order to reduce the density of the fluids in the riser annulus and therefore reduce the hydrostatic pressure within the wellbore.

Abstract:

The present invention relates to systems and methods useful in subterranean treatment operations. More particularly, the present invention relates to systems and methods for treating subterranean formations using low-molecular weight treatment fluids. Examples of methods of the present invention include methods of fracturing a subterranean formation; methods of enhancing production from multiple subterranean formations penetrated by a well bore during a single trip through the well bore; methods of enhancing production, in real time, from multiple subterranean formations penetrated by a well bore during a single trip through the well bore; and methods of reducing the cost of enhancing production from multiple subterranean formations penetrated by a well bore by stimulating multiple formations, on a single trip through the well bore, with a fluid that minimizes damage to the formation.
