Operation Control With Respect To Gel Content In Drilling Mud While Drilling, Baker Hughes Company

Defensive Publications Series

Drilling muds are often designed to build a gel to prevent cuttings from sinking. The gelled mud requires a higher pressure drop to circulate, so there should be special procedures for flow rate control with respect to gel content. Both the rates of gel building and gel breaking significantly impact on these procedures. The evaluation of gel parameters ensures safety and enables optimization of performance.

Wear Indication For Downhole Tools Hardfacing Application, Baker Hughes Company

Defensive Publications Series

Determination of the amount of wear on a downhole tool’s body at the rig site is necessary for certain downhole tools in order to decide if the measurement instrument needs to be re-calibrated. A slot with steadily increasing depth (tilted slot) is suggested to replace the previously used series of holes of different depth. By making the slot long enough, i.e. the angle shallow, the problem of gauging small depth differences is transformed into a relatively coarse measurement of length differences. Said method can for example be applied to all nuclear logging while drilling (LWD) tools, especially the gamma density …

A consumer system monitors the metadata of received message sequences to detect the group identifier and creates a temporary lookup table to track received sequence numbers. If a non-consecutive sequence number is detected, the consumer system pauses …

Rig-Site Rerun Recommendation System Based On Real-Time Load Records, Load History And Part-Number-Specific Maintenance Criteria, Baker Hughes Company

Defensive Publications Series

An early (while downhole and before pull out of hole) rerun recommendation was identified as a driver of cost saving because no/less back-up tools are required at drilling sites.

Evaluation of the maintenance needs according to established event-based-maintenance criteria indicates the depth of maintenance the assets would undergo in an AMO (Assembly, Maintenance and Overhaul) workshop. Under the assumption that low-level maintenances may be postponed, existing event-based-maintenance criteria can be reused as lay-down criteria - until a specific set of rules is identified.

Stability Enhancement Of Mesalamine Delayed-Release Tablets 1.2g, Anonymous

Defensive Publications Series

Mesalamine (5-aminosalicylic acid) is widely used for the treatment of inflammatory bowel disease (IBD), including ulcerative colitis. Commercially available mesalamine delayed-release formulations, such as LIALDA (Mesalamine) Delayed-Release Tablets 1.2 g, utilize a pH-dependent polymer film, which breaks down at or above pH 6.8, normally in the terminal ileum where mesalamine then begins to be released from the tablet core, enabling controlled drug release. However, the drug release profile of such formulations has been observed to change with storage, particularly at elevated temperatures. This article presents findings from formulation studies demonstrating that incorporating sodium ascorbate or sodium benzoate as stabilizers in …

Model-Based Data Fitting, Baker Hughes Company

Defensive Publications Series

This invention is potentially relevant in numerous areas/services. Many services rely upon measurements, which influence real-time decision making. Often the simplest approach to smoothen noisy data is to apply linear regression (e.g. line of best fit). However, such an assumption is not always the best and may result in less than optimal interpretation of the data. The algorithm outlined here is capable of selecting an appropriate model (based on data and SME input for the particular application) to improve the fit and interpretation/description of the data.

Apparatus, System, And Method For Wide Fields Of Illumination In Eye-Tracking Applications, Jon Bills

Defensive Publications Series

To enlarge the field-of-illumination (FOI), we propose a monolithic emitter solution, where we add the beamshaping functions directly over the light emitters (LED or laser) thorough nano/micro patterning approaches. The typical LED or laser emitter may have a flat finish surface (semiconductor material or some anti-reflection coating layers). In our proposal, we consider directly patterning beamshaping components onto the coating layer or semiconductor material through semiconductor lithography and etch process. Alternative approach may pattern the beamshaping components via imprint or other additive nano/micro manufacturing processes. One advantage to this solution is that the beamshaping function can be engineered to control …
