Abstract: A system and method of detecting subsurface karst features includes receiving surface mapping data. A potential surface pad location can be identified in view of the surface mapping data. A resistivity survey for the potential surface pad location can be designed. The resistivity survey can include at least one long line extending through a surface hole for each of one or more wellbores in the potential surface pad location, and a short line extending through the surface hole of one of the one or more wellbores, each short line intersecting the long line substantially at the surface hole of one of the one or more wellbores. High resistivity areas exceeding approximately 150 Ohm per meter can be identified as sub surface karst features within the resistivity survey.

Abstract: Disclosed are systems and methods for pressure testing coiled tubing (CT) in a well. A CT pressure testing device may include a CT connector for attaching to a CT segment and a pressure test housing defining a pressure chamber. A rod may extend through a top opening of the pressure test housing and through the CT connector to the severed end of the CT segment. A sealing plug coupled to a bottom end of the rod may create an interface between the CT connector and the CT segment. A force activator may apply a force to a top end of the rod, causing the rod to push the sealing plug into the CT segment and tighten the interface. A pump may pressurize the pressure chamber to perform a pressure test on the sealing plug. Accordingly, the CT pressure testing device may establish a well control barrier for the well.

Abstract: The invention is directed to stable and labile crosslinked water swellable polymeric microparticles that can be further gelled by covalent crosslinking in a transamidation reaction, methods for making same, and their various uses in the hygiene and medical arts, gel electrophoresis, packaging, agriculture, the cable industry, information technology, in the food industry, papermaking, use as flocculation aids, and the like. More particularly, the invention relates to a composition comprising expandable polymeric microparticles having labile crosslinkers and stable crosslinkers, said microparticle mixed with a fluid and an unreacted tertiary crosslinker comprising PEI or other polyamine based tertiary crosslinker that is capable of further crosslinking the microparticle on degradation of the labile crosslinker and swelling of the particle, so as to form a stable gel. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric microparticles are injected into a well and when the heat and/or pH of the well cause degradation of the labile crosslinker and when the microparticle expands, the tertiary crosslinker crosslinks the polymer to form a stable gel, thus diverting water to lower permeability regions and improving oil recovery.

Abstract: Method of monitoring produced water at each perforation or entry point by real time ion sensor deployed downhole to measure the content of water soluble ions is discussed. Methods of determining and differentiating nature of water breakthrough in oil production; such as between cycled injection water through a void space conduit, matrix swept injection water and formation water, especially as relates to offshore oil production, are also discussed. Real time ion sensors are deployed and compared with known standards to monitor and remediate water breakthrough, prevent scale deposition, and the like.

Abstract: Systems and methods of forming a seal employ a robust metal sealing unit for tubulars used in rotary drilling. Specifically, eutectic alloy is used to seal a tubular to a wellbore after drilling. A downhole heater melts the alloy, allowing the alloy to expand and drain before it cools and solidifies between the wellbore and tubular, forming a gas tight seal.

Abstract: The invention relates to the introduction of pressurized fluid, e.g. acid, into a subsea well directly from a vessel (33). A fluid injection assembly (20) is fitted to the top of a subsea Xmas tree (3), the assembly (20) including fail safe closed valve (21) which is controlled via a hydraulic line (31) from the vessel. The hose and assembly and valve are designed with an internal bore allowing a large diameter ball to be dropped (required for acid stimulation). The subsea subsea control module (8) on the Xmas tree is controlled from the producing platform.

Abstract: Methods and systems of analyzing and optimizing a seismic survey design are described. A system includes a plurality of seismic receivers disposed in a survey area at a plurality of receiver locations. The system also includes a plurality of seismic sources disposed in the survey area at a plurality of source locations. The plurality of receiver locations and the plurality of source locations are specified by a seismic survey design minimizing any artifacts identified in a filtered spectrum obtained by applying a frequency-wavenumber filter to a central midpoint space summation. The plurality of receiver locations and the plurality of source locations are determined based on a comparison of the filtered spectrum to a second filtered spectrum. The second filtered spectrum is for a second central midpoint space summation.

Abstract: Method of decomposing high molecular weight polymer downhole to prevent chelation of iron by residual high molecular weight polymer thereby producing flowback without iron contamination as chelated iron. A secondary method is also described to treat iron chelated produced water with oxidants at surface conditions, utilizing aluminum electrolytes, specifically low basicity polyaluminum chloride, to either co-precipitate residual polymer and bound iron, or to substitute chelated iron with aluminum in the polymer-metal complex, resulting in liberating of iron to enable neutral pH oxidation and removal by precipitation, coagulation, flocculation and physical separation. The produced water with removed iron can be then stored or re-used for other oilfield applications.
