Abstract: A method of estimating fluid composition in an earth formation includes: generating at least one pulsed neutron measurement by a pulsed neutron tool; estimating a pulsed neutron fluid saturation by analyzing the at least one pulsed neutron measurement via a pulsed neutron model of the earth formation, the pulsed neutron model including expected pulsed neutron measurements relative to selected fluid composition and properties; comparing the pulsed neutron fluid saturation to a reference fluid saturation estimated via a downhole tool; adjusting the pulsed neutron model to at least substantially eliminate a difference between the pulsed neutron fluid saturation and the reference fluid saturation by adjusting at least one of the selected fluid composition and the selected fluid properties; and estimating at least one of the fluid composition and the fluid properties based on the adjusted model.

Abstract: An improved, high strength construction system that uses post tensioning. It is comprised of a series of interconnected, super heavy duty hollow core blocks 102 with minimal ducts 103, a series of tendons 105, and a plurality of anchors or plates 104 with additional features. The system 101 is configured with the plurality of adjacent blocks 102 contiguous and touching one another and demountably coupled to each other by means of the tendons 105 and anchors 103. The unique features include a strong, durable full plate 104 and bolt 105 both of which may be treated for corrosion resistance. This new coupling results in a structure that is far stronger than an ordinary block structure built with mortar and standard reinforcing. The SYSTEM has more predictable and controlled strength which is stronger than most reinforced concrete systems.

Abstract: An improved mortar less masonry structure comprising a plurality of concrete masonry units connected to each other by metal bars and metal threaded fasteners thereby forming a reinforcing skeletal system for a post tensioned structure. The improved system has been developed for use in constructing various types of masonry structures. The improvements of the system feature masonry units with recessed channels, pocket channels, or fully embedded bars as anchors. The bolt acts as the tendon for the post tensioning system which traverse the hollow cavities as ducts. Other new features teach a strong and durable full plate anchor and high strength tendons for defensive and anti-terrorism structures. This is an improved building system that demountably couples each individual masonry unit by a bar and bolt system. This coupling results in stronger, faster, and cheaper construction of masonry structures.

Abstract: A mortar less masonry structure comprising a plurality of regular masonry blocks and/or bricks connected to each other by a plurality of metal bars and a plurality of standard metal threaded fasteners thereby forming a post tensioned structure. Preferably, the blocks are operatively connected to each other as a structure by simple mechanical tools. Each interconnection results in a unitized post tensioned member that, when interconnected to the adjacent members, forms a comparatively higher strength structure than systems made of mortar and reinforced mortar. The method used to create this structure is a simple, waterless, mortar less interconnection process that is completed by a series of simple individual steps of fastening the blocks and bars into a strong and durable structure. Once connected the structure is strong and durable. If desired, the structure may be disassembled and the components be re-used.

Abstract: An isolation system employing a containment zone within the casing or tubing of a wellbore. The containment zone can be isolated from the wellbore pressure and leak tested to ensure no leakage is occurring across the zone. The isolation system prevents wellbore pressure below the system from communicating with the surface, thereby allowing for safe egress of tools from within the wellbore.
