| 20090294134 | CAPILLARY HANGER ARRANGEMENT FOR DEPLOYING CONTROL LINE IN EXISTING WELLHEAD - To deploy a capillary string through a wellhead to a downhole safety valve, a control port and a retention port are drilled in an adapter between a casing hanger and a gate valve or elsewhere. The capillary string is connected to a first port of a capillary hanger and installed through the wellhead. The capillary hanger is landed on a tubing hanger, and a side port on the capillary hanger communicates with the control port. Because the side port's location may not align with the control port, operators may need to measure how long the capillary hanger should be. A control line connects to the control port in the wellhead's side to communicate with the capillary line, and a retention rod inserts in the retention port to support the capillary hanger. | 12-03-2009 |
| 20090294136 | Surface controlled subsurface safety valve having integral pack-off - A safety valve apparatus has a housing with a bore and a projection in the bore. A flapper rotatably disposed on the housing is movable relative to the bore between opened and closed positions, and a packing element disposed on the housing is compressible to engage an inner conduit wall surrounding the housing. An upper sleeve disposed within the bore above the projection is hydraulically movable from a first position to a second position via the hydraulic communication with a port in the projection. The first sleeve when moved to the second position compresses the packing element. A piston disposed in the housing hydraulically communicates with the port and couples to a second sleeve disposed within the bore below the projection. The second sleeve conceals the piston and is hydraulically movable via the hydraulic communication of the port with the piston to open and close the flapper. | 12-03-2009 |
| 20100084136 | Power Slip Assembly for Wellhead Casing and Wellbore Tubing - A power slip extends a joint from tubing disposed in casing at a well so that a casing head can install on the casing and the tubing can be packed-off from the casing. The joint attaches to an inner sleeve having collet members that fit onto the inner tubing so that the joint extends thereabove. An outer sleeve and interlocking collet assemble together and install onto the inner sleeve. The collet threads onto the inner sleeve and forces the outer sleeve downward onto the inner sleeve. Being forced, the outer sleeve causes the collet members to engage around the inner tubing. The casing head then installs on the casing with the joint extending up through the head's bowl. An H-plate installs in the open bowl around the extended joint, and another pack-off installs on the joint to pack it off from a spool attaching to the casing head. | 04-08-2010 |

| 20090107685 | Wellhead Completion Assembly Capable of Versatile Arrangements - A wellhead completion assembly has a head connected to surface casing. A rotatable flange or the like can be used to connect various components to a threaded end of the head. A casing hanger installs in the head, and the hanger's upper end extends beyond the head's top edge. This exposed end has an external threaded connection to connect to various wellhead components using a rotatable flange or the like. For example, a locking ring can threadably connect to the head's threaded end to support the hanger in the head. Then, a rotatable flange can threadably connect to the hanger's exposed end so that another component, such as a completion spool or gate valve, can nippled up directly to the hanger. When the hanger is fluted, a pack-off assembly can allow testing off inner and outer sealing integrity via a test port accessible through an opening in the locking ring. | 04-30-2009 |

| 20090271045 | Irrigation flow converter, monitoring system and intelligent water management system - The present invention is directed to an intelligent water management irrigation system for monitoring the total water usage for a billing site and preventing cumulative water usage from exceeding a water budget by adjusting the amount of water used for irrigation. Irrigation zone priority values are selected for each irrigation zone that specify a percentage of the full water need that the foliage in the zone can survive and are saved in an intelligent water management irrigation (IWMI) controller. The IWMI controller receives water usage information originating from a property's water meter and compares the measured water usage with the allowable water budget. Water usage is tracked separately for the household use and landscape use (irrigation). Prior to each irrigation cycle, the IWMI controller estimates the amount of water that will be needed by the landscape and for household use during the remainder of a billing cycle; household use is given precedence over landscape use. If the water budget will support both, irrigation can proceed normally. If the budget will not support both, the IWMI controller estimates the amount of water needed for the remainder of the billing cycle if only a priority watering amount is allocated for each landscape zone. If the water budget will support priority irrigation, landscape watering can proceed in priority irrigation mode. If the water budget will not support priority irrigation watering, the irrigation cycle is skipped and the water usage estimations are recalculated prior to the next irrigation cycle. | 10-29-2009 |
