Patent number: 9103206Abstract: A method of increasing the fracture resistance of a low permeability formation that includes emplacing a wellbore fluid in a wellbore through the low permeability formation, the wellbore fluid comprising: a settable carrier fluid; and a solid particulate bridging material; increasing the pressure in the wellbore such that fractures are formed in the formation; allowing the settable carrier fluid to enter the fractures; bridging and sealing the mouths of the fractures to form a substantially impermeable bridge proximate the mouth of the fractures thereby strengthening the formation; and holding the increased pressure for an amount of time sufficient for setting of the carrier fluid in the fractures is disclosed.Type: GrantFiled: August 1, 2008Date of Patent: August 11, 2015Assignees: M-I LLC, BP Corporation North America Inc.Inventors: Mark William Alberty, Mark Aston, Jim Friedheim, Mark Sanders, Randall Sant

Patent number: 8499830Abstract: Methods are described using resistivity measurements obtained while drilling one or more offset wells using a drilling mud to guide drilling of one or more uncased intervals of a well to identify a casing point or points in the uncased intervals of the well. Resistivity data is gathered during drilling the offset well and prior to penetrating a region of interest of a known subterranean formation. The drill string in the uncased interval of the well progresses toward the region of interest, using resistivity data at similar depths to identify a casing point while the drill bit advances toward but does not penetrate the region. In certain embodiments resistivity may also be obtained in front of the drill bit in the uncased interval of the well and used in conjunction with the offset well resistivity data to identify casing points in the uncased intervals of the well.Type: GrantFiled: July 7, 2008Date of Patent: August 6, 2013Assignee: BP Corporation North America Inc.Inventor: Mark William Alberty

Publication number: 20110297380Abstract: Methods of jarring include communicating between a surface command device and jars in a drill string, the drill string composed of spaced apart jars positioned in a corresponding plurality of wired and/or wireless pipe sections. The methods include selectively controlling charging, firing, amount of force, and/or direction of force of the jars using digitally-controlled surface command devices. One method includes firing a sub-set or all of the jars in a controlled manner and determining depth of a stuck drill string section through analysis of behavior or performance of the fired jars. Other methods include subsequently firing one or more of the jars again below the stuck drill string section. Other methods include selectively firing, using digital signals from the surface command device, jars sequenced in time so that their forces meet in a constructive or destructive manner at a preselected point in the drill string.Type: ApplicationFiled: June 3, 2011Publication date: December 8, 2011Applicants: BP CORPORATION NORTH AMERICA INC.Inventors: Mark William Alberty, Warren J.

Patent number: 8061442Abstract: Methods of using resistivity ahead of a drill bit measurements obtained while drilling a subterranean well using a drilling mud. Resistivity data ahead of the bit is gathered during drilling and prior to penetrating a region of interest of a known subterranean formation using the drill bit and the drilling mud. The drill string progresses at known dip and azimuth angles toward the subterranean formation. The resistivity data is used to determine pore pressure ahead of the drill bit in the formation as a function of resistivity ahead of the drill bit in the formation while the drill bit advances toward but before the bit penetrates the formation while drilling.Type: GrantFiled: July 7, 2008Date of Patent: November 22, 2011Assignee: BP Corporation North America Inc.Inventor: Mark William Alberty

Patent number: 7861801Abstract: Methods are described using resistivity ahead of a drill bit measurements obtained while drilling a subterranean well using a drilling mud. Resistivity data ahead of the bit is gathered during drilling and prior to penetrating a region of interest of a target subterranean formation using the drill bit and the drilling mud. The drill string progresses at target dip and azimuth angles toward the region on interest. The resistivity data is used to determine the top of the region of interest while the drill bit advances toward but does not penetrate the region. A core bit is then installed and a whole core of the region of interest obtained. Resistivity ahead of a drill bit measurements obtained while drilling a subterranean well may also be compared with conventional resistivity measurements obtained from one or more offset wells.Type: GrantFiled: July 7, 2008Date of Patent: January 4, 2011Assignee: BP Corporation North America Inc.Inventor: Mark William Alberty

In certain embodiments, the methods include redirecting the drill bit while drilling toward locations in the formation where pore pressure is within an acceptable range. In other embodiments, a drilling mud parameter is adjusted based on the pore pressure in front of the bit.Type: ApplicationFiled: July 7, 2008Publication date: January 7, 2010Applicant: BP Corporation North America, Inc.Inventor: Mark William Alberty
