Patent number: 11035195Abstract: Methods of mitigating lost circulation while drilling a wellbore. The methods include circulating a drilling mud to a downhole end of the wellbore via a drill string and, during the circulating, drilling the wellbore with a drill bit of the drill string. The methods also include detecting lost circulation within the wellbore while drilling the wellbore and include providing a monomer solution to the wellbore. The methods further include providing a catalyst to the wellbore responsive to detecting the lost circulation event and combining the monomer solution and the catalyst to polymerize a monomer from the monomer solution, within the wellbore, and forming a viscous plug within the wellbore. Subsequent to the combining, the methods include flowing at least a portion of the viscous plug within the wellbore and into a zone of lost circulation that extends within a subsurface region.Type: GrantFiled: November 13, 2018Date of Patent: June 15, 2021Assignee: ExxonMobil Upstream Research CompanyInventors: Bill R. Meeks, Timothy J. Nedwed, Douglas A. Mitchell, Rachna Jain, Kaustubh S. Kulkarni

Publication number: 20200208491Abstract: Systems, apparatus, and methods for controlling a well blowout comprising: a flow control device such as a blowout preventer on a wellbore, the primary throughbore of the flow control device comprising internal dimensional irregularities creating a non-uniform flow path in the primary throughbore which as sufficient fluid rate may enhance pressure fluid pressure drop therein; a control fluid aperture fluidly connected with the wellbore for introducing a control fluid through a control fluid aperture and into the primary throughbore while wellbore fluid flows through the wellbore; a hydrate component introduction pump for introducing the hydrate inducing component into the control fluid; a hydrate inducing fluid aperture positioned in the wellbore conduit below the control fluid aperture for introducing the hydrate inducing fluid into the wellbore and for combining with the control fluid that includes the hydrate inducing fluid to form a saturated hydrate forming fluid mixture within the primary throughbore whType: ApplicationFiled: October 29, 2019Publication date: July 2, 2020Inventors: Timothy J. Nedwed, William R. Meeks, Rachna Jain, Kaustubh S. Kulkarni

Publication number: 20190105265Abstract: A solid drug core insert can be manufactured by injecting a liquid mixture comprising a therapeutic agent and a matrix precursor into a sheath body. The injection can be conducted at subambient temperatures. The mixture is cured to form a solid drug-matrix core. The therapeutic agent can be a liquid at about room temperature that forms a dispersion of droplets in the matrix material. A surface of the solid drug core is exposed, for example by cutting the tube, and the exposed surface of the solid drug core releases therapeutic quantities of the therapeutic agent when implanted into the patient. In some embodiments, the insert body inhibits release of the therapeutic agent, for example with a material substantially impermeable to the therapeutic agent, such that the therapeutic quantities are released through the exposed surface, thereby avoiding release of the therapeutic agent to non-target tissues.Type: ApplicationFiled: October 11, 2018Publication date: April 11, 2019Applicant: Mati Therapeutics Inc.Inventors: Deepank Utkhede, JR., Robert Shimizu, Rachna Jain, Stephen Boyd, Hanson S Gifford, Eugene De Juan, Cary Reich

Publication number: 20160166430Abstract: Lacrimal implants and related methods providing secure retention within the lacrimal punctum of an eye are described. The lacrimal implants can comprise a implant body configured for at least partial insertion through the lacrimal punctum and into a lacrimal canaliculus. The implant body can include a deformable retention structure that can be configured to substantially encapsulate an expandable retention element. In some examples, the expandable retention element can include a fluid absorbing material, which can be exposed to fluid such as via a fluid permeable retainer or a fluid permeable aperture. As the fluid absorbing material retains fluid (i.e., upon acceptance of fluid into the retention structure), its size increases and its shape can change to urge one or more portions of the retention structure outward, such as against a wall of the lacrimal canaliculus, thereby securely retaining the lacrimal implant within the punctum.Type: ApplicationFiled: December 14, 2015Publication date: June 16, 2016Applicant: Mati Therapeutics Inc.Inventors: Rachna Jain, Robert W.
