Title: Methods and apparatus for optimizing well production
Inventor: HEARN WILLIAM
IPC: E21B34/16
Filed: 2006-07-12
Abstract: Embodiments of the present invention generally relates to methods and apparatus for operating an artificial lift well. In one embodiment, the well is operated between an on cycle and an off cycle. Preferably, the off cycle is determined by detecting an increase in the pressure differential between the casing pressure and the tubing pressure. In another embodiment, the well is optimized by measuring the production of the well in one cycle of operation. The measured production is compared to the production of a previous cycle. A controller then optimizes the well based on the increase or decrease of the production from the previous cycle.

Abstract: An ablation device, including a catheter and an ablation element incorporating one or more balloons at the distal end of the catheter, has a continuous passageway extending through it from the proximal end of the catheter to the distal side of the expandable ablation element. The ablation device ablates tissue by subjecting it to ultrasound energy, cryogenic energy, chemical, laser beam, microwave, or radiation energy. A probe carrying electrodes is introduced through this passageway and deploys, under the influence of its own resilience, to a structure incorporating a loop which is automatically aligned with the axis of the expandable ablation device, so that minimal manipulation is required to place the probe. Pulmonary vein potential is monitored in real time via the electrodes. The probe may have an atraumatic tip with a ball formed at the leading edge. The atraumatic tip prevents any tissue damage such as perforation of heart wall.

Abstract: An access point generates beacons at different power levels at different times to provide an acceptable tradeoff between coverage area associated with the beacons and outage experienced at nearby access terminals. For example, a femto access point may transmit beacons at a relatively low power for a relatively long period of time to reduce interference at nearby access terminals that are being served by a macro access point. The femto access point may then transmit beacons at a relatively high power for a relatively short period of time to enable nearby access terminals to receive the beacons. Also, a given transmit chain may be used to provide frequency hopping of high and low power beacons.

Title: Relocatable systems and processes for recovery of bitumen from oil sands
Inventor: ADEYINKA OLUSOLA B
IPC: C10G1/04
Filed: 2011-06-27
Abstract: Relocatable systems and processes for processing oil sands are described.  Relocatable components are employed to permit oil sand processing to be conducted near a mine face, and relocated as the mine face recedes. Systems described incorporate formation of a slurry in a relocatable slurry system, and subsequent agglomeration of solids. A high quality bitumen product is formed when processed further using solvent extraction, having water and solids content that exceeds downstream processing and pipeline requirements. An embodiment of the system comprises a relocatable slurry system, relocatable to a mine face and in fluid communication with a relocatable pipeline. Flow of the slurry in combination with appropriate water injection through the relocatable pipeline causes agglomeration of fines within the slurry.  Bitumen/solvent mixtures can be filtered from the agglomerates within downstream solvent extraction system components. A clean and/or fungible product can be formed.  Dry tailings may be back-filled in-pit.
