摘要:
The present invention is, in some embodiments directed to methods for optimizing wellbore displacement operations via in situ fluid property assessment/monitoring. By monitoring fluid properties in situ (i.e., downhole), fluid property assessment is direct instead of being inferred. Additionally, wherein such assessment/monitoring is carried out in real time, changes to the displacement fluid can be made “on-the-fly,” thereby contributing to an enhancement of the overall efficiency of the method.

This document discloses electroporation vessels, electrocompetent cells that have been aliquoted and frozen in electroporation vessels, and a number of other apparatuses, kits, and methods for electroporation. Some embodiments of electroporation vessels described herein may include a pair of opposing walls that are downwardly angled toward one another in a gap between two electrode surfaces. Further embodiments of devices and methods described herein may eliminate the need for an end user to transfer competent cells from a capped tube to electroporation cuvette, thereby saving time and producing less waste.

A lifting device sensor unit is disclosed. In one embodiment, the sensor unit comprises a housing configured to removably couple about a load line of a lifting device. A first global navigation satellite system (GNSS) receiver is coupled with the housing and is configured for determining a sensor unit position in three dimensions. A load monitor is coupled with the housing and is configured for monitoring a load coupled with the load line, including monitoring a load position and a load orientation of the load. A wireless transceiver is coupled with the housing and is configured for wirelessly providing information including the load position, the load orientation, and the sensor unit position, to a display unit located apart from the sensor unit.

A bio-organic composition includes residues of a fatty acid glyceride-containing composition, residues of a first epoxide or glycol, and the residues of a second epoxide. The fatty acid glyceride-containing composition is characterized by the viscosity at room temperature. The first epoxide or glycol and second epoxides are present in a sufficient amount that the room temperature viscosity of the bio-organic composition is lower than the room temperature viscosity of the vegetable oil prior to formulation and/or the first epoxide or glycol and second epoxides are present in a sufficient amount that the pour point of the bio-organic composition is lower than the pour point of the fatty acid glyceride-containing composition prior to formulation.

The present invention provides a system and method for dramatically increasing the speed of generating and transmitting electronic messages to one or more recipients over a communication link. When the inventive system processes a new outgoing message for transmission, by obtaining a number of predetermined types of values, the system identifies one or more portions of the message as belonging to a particular category, and, for each portion that is not already present in the category, stores the corresponding obtained value along with the message portion in the category. Then, for each outgoing message that includes at least one portion that matches one or more of the portions stored in any of the categories, the system uses the stored values for the matching message portions of the outgoing messages, instead of performing processing on those message portions. Thus, instead of processing an entire outgoing message for transmission, the inventive system only needs to process the portion of the message that is not found in any of the categories. Furthermore, as the number of stored and categorized processed message portions and corresponding values grows, the inventive system is able to utilize more and more of previously obtained values for outgoing messages, and thus greatly reduces the time required to prepare outgoing messages for transmission.

A sensor unit system is disclosed. In one embodiment, the sensor unit comprises a sensor unit comprising a first global navigation satellite system (GNSS) receiver which is configured for determining a position of the sensor unit in three dimensions. The sensor unit system further comprises a display unit comprising a second GNSS receiver. The display unit is communicatively coupled with the sensor unit via a wireless Personal Area Network (PAN) connection. The display unit and the sensor unit are physically separate entities.
摘要:
The present invention provides a recess within an expandable downhole tubular, such as an expandable sand screen. The recess resides within the wall, such as the outer shroud of an expandable sand screen. The recess serves as a housing for instrumentation lines, fiber optics, control lines, or downhole instrumentation. By placing the lines and instrumentation within a wall of the expandable downhole tool, the tool can be expanded into the wall of the wellbore without leaving a channel outside of the tool through which formation fluids might vertically migrate. The recess is useful in both cased hole and open hole completions. In one embodiment, the recess serves as a housing for an encapsulation which itself may house instrumentation lines, control lines, and downhole instrumentation.
