Title: Mesh screen enclosing a cement ingress port
Inventor: VINCENT RAY
IPC: E21B43/10
Filed: 2002-04-24
Abstract: A section of outer annulus 20 between a downhole tubular 12 and the borehole wall 10 or casing is isolated by axially spaced annular packers 14, 16. Between these barriers, the tubular has two ports 35, 66 for the egress and ingress of fluids. A screen 90 encloses one of the ports to limit the size of particles that can pass therethrough. To cement the annulus, a cementing tool 100 is placed in the tubular and cement with particulates added is pumped out of the egress port and into the annulus. Well fluids are displaced by the cement to the inside 13 of the tubular via the ingress port. When cement reaches the screen over this port the added particles block the screen mesh and prevent the ingress of cement, causing the annulus to fill with cement and generating a backpressure that is detectable at the surface and indicates to the operators that sufficient cement has been delivered to the annulus.

Title: Removing particulates from a fluid
Inventor: CARRIER MICHELLE
IPC: B03C5/00
Filed: 2003-08-12
Abstract: A method of removing particulate solids from an oil based drilling or completion fluid 1 comprises exposing the fluid to an electric field to electrically migrate particulate solids suspended therein, and collecting the migrated particulate solids 13 to remove them from the fluid. Preferably, the fluid is recycled by means of a continuous flow device wherein fluid enters upstream of an electrically conductive, horizontal pipe 2, that branches into two valved 5, 6 sections 3, 4. Advantageously, during use, an applied voltage causes particles to deposit on electrodes 7 and fluid with reduced particles is allowed to re-circulate via a branched section 3 of the pipe 2. After a period of time flow is re-directed to the other branched section of pipe 4 and the applied voltage is reversed causing the release of deposited particles into the fluid which is then directed to a collection vessel. Advantageously, the performance of the fluid is improved by removal of the particulate solids.
