Abstract: Fluid systems may contain elements to provide changes in bulk fluid density in response to various environmental conditions. One environmental driver to the variable density is pressure; other environmental drivers include, but are not limited to, temperature or changes in chemistry. The variable density of the fluid is beneficial for controlling sub-surface pressures within desirable pore pressure and fracture gradient envelopes. The variability of fluid density permits construction and operation of a wellbore with much longer hole sections than when using conventional single gradient fluids.

Abstract: Composite tubulars that have not been polymerized and are thus flexible enou gh to be coiled are delivered into a wellbore and expanded. The expansion occur s from an external catalist such as heat or releases the internal catalyst and allows the expanded tubular to become rigid. Optionally, healing agents can be imbedded in the tubular wall to be released to seal subsequently forming cracks.

Abstract: An improved electrical submersible pump is disclosed in which a processor (37) downhole is utilized to monitor one or more subsurface conditions, to record data, and to alter at least one operating condition of the electrical submersible pump (23). Novel uses are described for downhole gas compression, the delivery of particulate matter to wellbore sites, and for the disposal of waste.

Abstract: A system for producing a field is disclosed. The field includes a main access well with a first branch well extending therefrom. A separator for separating oil and water is placed in the first branch well. In an alternate embodiment, the separator may be contained within the main access well. A second branch well may also extend from the main access well and may contain a disposal assembly that is operatively associated with the separator. The first and second branch wells may intersect the same reservoir or different reservoirs.

Abstract: An active differential pressure device (APD device) in fluid communication with a returning fluid creates a differential pressure across the device, which controls pressure below the APD Device. In embodiments, a control unit controls the APD Device to provide a selected pressure differential at a wellbore bottom, adjacent a casing shoe, in an intermediate wellbore location, or in a casing. In one arrangement, the control system is pre-set at the surface such that the APD Device provides a substantially constant pressure differential. In other arrangements, the control system adjusts an operating parameter of the APD Device to provide a desired pressure differential in response to one or more measured parameters. Devices such as an adjustable bypass can be used to control the APD Device. In other embodiments, one or more flow control devices coupled to the return fluid reduce the effective pressure differential provided by the APD Device.
