Publication number: 20170152742Abstract: A fiber optic slickline. The slickline includes fiber optic communication means without full downhole power transmitting capability. Nevertheless, the slickline is configured to accommodate an axial load up to, and in excess of 2,000 lbs. Downhole tools and tool assemblies are configured with opto-electronic interfacing features so as to remain electronically compatible while also taking advantage of fiber optic communications afforded over the slickline. The slickline and tools may be employed in logging and other downhole operations in a manner that provides real time communication with substantially reduced surface equipment expense in terms of footprint and power requirements.Type: ApplicationFiled: February 13, 2017Publication date: June 1, 2017Inventor: Kalim Ullah

Patent number: 9285547Abstract: A joint for disposing between a rotatable drum and stationary surface equipment. The joint serves as a channel through which optical data from a well access line may be routed through the rotating drum and to the stationary equipment for processing. The optical data may be routed in a manner that allows for multi-fiber transmissions with one fiber dedicated to uphole transmissions and another dedicated to downhole transmissions. This is achieved through embodiments of the joint in spite of the separate optical channels involved sharing the same central axis to allow for data transfer between moving and stationary joint components.Type: GrantFiled: November 24, 2014Date of Patent: March 15, 2016Assignee: Schlumberger Technology CorporationInventor: Kalim Ullah

Patent number: 9222116Abstract: A microfluidic device and method for enzymatic processing of ultra-long macromolecules is accomplished using a microfluidic device a reaction chamber with a first manifold, a second manifold, and a plurality of reaction channels. Each reaction channel extends from the first manifold to the second manifold. First inlet and outlet channels fill the reaction channels via the manifolds with one or more macromolecule containers suspended in a first carrier fluid. The first inlet and outlet channels are configured such that a flow is guided through the reaction channels, and an enzymatic reagent is fed to the reaction chamber essentially without displacing the macromolecule containers trapped in the reaction channels. The second set of inlets and outlets are configured such that a flow established from the second inlet to the second outlet is guided through at least one of the manifolds and bypasses the reaction channels.Type: GrantFiled: October 24, 2011Date of Patent: December 29, 2015Assignees: DANMARKS TEKNISKE UNIVERSITAT—DTU, THE CHANCELLOR, MASTERS AND SCHOLARS OF THE UNIVERSITY OF OXFORDInventors: Rodolphe Marie, Anders Kristensen, Kristian Hagsted Rasmussen, Kalim Ullah Mir
