Published: November 2020

Objective: Creating generalizable knowledge across institutions is a step beyond a successful local research project. The purpose of this article is to share the process and lessons learned from expanding a survey tool developed and piloted at a single veterinary college to its deployment at multiple veterinary colleges in the United States and Canada.

Population or problem: Little guidance exists on expanding a survey developed for a single institution to distribution to health professions students across multiple institutions.

Methods: In June 2016, the first author of the survey contacted librarians from veterinary colleges to explore a possible multi-institution study to investigate student behaviors and perceptions around scientific information. Librarians from twenty-nine institutions initially expressed interest. Those at fifteen institutions participated in initial planning, and eight elected to distribute the survey. Of these, seven submitted for IRB review at their own institution and one institution facilitated the distribution of the survey under the original institution’s IRB exemption.

Findings: The IRB submission process and requirements varied by participating institution. Mean time from submission to approval was 10 days (range: 2-31 days). Several changes were made to the survey based on the recommendations of participating librarians, ranging from simplifying the method of survey distribution to modifying specific questions to make them meaningful across institutions. As participating institutions did not have synchronized academic calendars, the survey distribution took a staggered approach between institutions based on IRB review and varying institutional processes.

Conclusions: Expanding even a simple IRB-exempt survey from one institution to others requires careful consideration of local practices, attention to differences in the IRB process, and ethical considerations for recruiting students where librarians serve as instructors or hold other positions of influence. Attempts to standardize recruitment messaging and survey questions for generalizable results required compromise by the librarian researchers at participating institutions.

Impact of Value-Based Reimbursement on Health-Care Disparities for Total Joint Arthroplasty Candidates
Authors: Grobaty Lauren , Lajam Claudette , Hutzler Lorraine 
Published: November 2020

» As the U.S. Centers for Medicare & Medicaid Services (CMS) implements value-based reimbursement models based on predetermined outcome measures, access to total joint arthroplasty (TJA) is jeopardized for patients who are disproportionately affected by conditions that predispose them to higher odds of complications.» Obesity, depression, and chronic illness, each of which occur at disproportionately higher rates in minorities or individuals in lower socioeconomic brackets, are individually associated with worse TJA postoperative outcomes, including longer hospital lengths of stay and higher rates of readmission within 90 days.» Medicaid may even be considered an independent risk factor for worse outcome measures with TJA as enrollees have higher rates of postoperative mortality and complications and longer lengths of stay than patients on Medicare or with private insurance.» As same-day discharge for TJA becomes more common, eligibility requirements for the procedure tighten, and existing disparities in access to the procedure will be further exacerbated.» The current CMS uniform quality metrics endanger access to TJA for patients in certain racial and socioeconomic groups and oblige physicians who treat more complex patients to jeopardize their reimbursement.

ABSTRACTTerrestrial sedimentary archives record critical information about environment and climate of the past, as well as provide insights into the style, timing, and magnitude of structural deformation in a region. The Cretaceous Newark Canyon Formation, located in central Nevada, USA, was deposited in the hinterland of the Sevier fold–thrust belt during the North American Cordilleran orogeny. While previous research has focused on the coarser-grained, fluvial components of the Newark Canyon Formation, the carbonate and finer-grained facies of this formation remain comparatively understudied. A more complete understanding of the Newark Canyon Formation provides insights into Cretaceous syndeformational deposition in the Central Nevada thrust belt, serves as a useful case study for deconvolving the influence of tectonic and climatic forces on sedimentation in both the North American Cordillera and other contractional orogens, and will provide a critical foundation upon which to build future paleoclimate and paleoaltimetry studies.We combine facies descriptions, stratigraphic measurements, and optical and cathodoluminescence petrography to develop a comprehensive depositional model for the Newark Canyon Formation. We identify six distinct facies that show that the Newark Canyon Formation evolved through four stages of deposition: 1) an anastomosing river system with palustrine interchannel areas, 2) a braided river system, 3) a balance-filled, carbonate-bearing lacustrine system, and 4) a second braided river system. Although climate undoubtedly played a role, we suggest that the deposition and coeval deformation of the synorogenic Newark Canyon Formation was in direct response to the construction of east-vergent contractional structures proximal to the type section. Comparison to other contemporary terrestrial sedimentary basins deposited in a variety of tectonic settings provides helpful insights into the influences of regional tectonics, regional and global climate, catchment characteristics, underlying lithologies, and subcrop geology in the preserved sedimentary record.
A Novel Phase Transition Loss Circulation Solution for Severe Losses Scenario: Case Histories from Middle East and Africa

Published: November 2020

Abstract
Lost circulation is a major contributor to non-productive time (NPT). Any efforts to better understand the factors that lead to it and subsequently identify a suitable cure will translate to tremendous savings of time and money for operators.
Conventional materials such as calcium carbonate, nut shells, graphites and fibers are successful in curing many cases of seepage and partial lost circulation. However, there is a practical limit to the concentration of these materials used to combat the most severe losses due to the limitation of pumps and drilling assembly. In porous formations, high fluid loss squeeze pills have seen some success in reducing losses by forming a high compressive strength plug, but these pills do not have a good success rate in large fractures or vugular formations. Such challenges are better addressed by cross-linking pills, but even this solution does not always have a high success rate due to the low compressive strength of the formed plug.
The new phase-transforming loss circulation material (PTLCM) was designed to be pumped easily and achieve thixotropic behaviour under downhole conditions, resisting losses in the thief zone prior to setting as a rigid plug with high compressive strength. A setting-control additive ensures the LCM does not prematurely set. The additive is used at a concentration calculated by considering the time required for pumping and the bottom hole temperature (BHT) in the thief zone. After the LCM sets, a high compressive strength solid plug is formed that can resist fluid loss to the formation. The LCM has a high acid solubility of ~95%, making this system a viable option for deploying in reservoir sections, depending on the client requirement and well conditions.
This paper describes two recent successful applications deploying this novel technology.
Case Study #1: While drilling in sandstone, the well experienced total losses, which presented an immediate challenge to maintain hydrostatic pressure. The operator responded by pumping several conventional pills loaded with a broad particle size range of fibers, granules and polymers. These pills were unsuccessful at healing the losses, so the operator opted to deploy the new technology LCM. The losses were cured successfully with a single application.
Case study #2: Wells drilled in the Western Desert have traditionally experienced severe to total losses while drilling fractured dolomite. Frequently, such events have been difficult to cure by conventional means. The only solution has been multiple applications of cement plugs to heal the losses. This case study describes a well with dynamic losses of more than 150 bbl/hr that were healed by spotting one pill through the circulating sub across the thief zone. The losses were successfully cured, allowing the operator to continue drilling.
Underground Coal Gasification: A New Source of Gas
Authors: Centofanti John 
Published: November 2020

Abstract
This paper will introduce a novel source of unconventional gas, called Underground Coal Gasification (UCG), also known as In-Situ Gasification (ISG), which has been around for a long time. Due to the inexpensive cost of oil and gas, along with the abundance of coal and the low cost of mining coal seams close to the surface, UCG has not attracted a lot of attention in the past. With the demand and price for gas increasing and the move away from mining coal, UCG is becoming more attractive as a way of extracting energy from deep uneconomic coal deposits and at the same time, lowering GHG emissions and reducing the environmental impact to the landscape.
With the majority of the world's coal deposits being uneconomic to mine and with the lack of gas reserves in most countries, UCG provides the perfect alternative to produce gas from coal without the environmental impact. There are numerous advantages to extracting syngas from coal seams, when compared to conventional coal mining and to CSG (Coal Seam Gas).
Deployment of One of Its Kind Slim Coiled Tubing Tractor to Overcome Reach Issue in Extended Reach Restricted Smart Completed Wells

Published: November 2020

Abstract
Several extended reach-restricted completion-smart wells required matrix acid stimulation using Coiled Tubing (CT). These wells are equipped with Mechanical Formation Isolation Valve (MFIV) in the tubing end which needs to be reopened by using CT to access mother-bore for performing acid job. CT simulation results for these wells showed coil can reach only 60-70% of open hole interval. Calibrated friction coefficients were used in CT simulation based on the data base developed from other wells in the same area. Only CT-Tractor simulation showed 100% reach with maximum tractor over pull of 3200 lbs from the lock-up depth.
World’s slimmest CT tractor was developed in collaboration specifically to address the challenges of extending CT reach past lock-up depth during acidizing and other intervention jobs in minimum restriction extended reach well. The world’s slimmest tractor (2 1/8" outside diameter; OD) was able to provide a pulling force of 3200 lbs and was powered by intervention fluid pumped through coiled tubing. The tractor has many failsafe features and self-cleaning mechanism of gripper arms to overcome the challenges encountered while tractoring in open hole.
Four smart wells (with minimum restriction 2.81") were successfully matrix acid stimulated while the CT-Tractor combination were able to extend the reach of CT beyond lock-up depth. CT-Tractor was run-in-hole (RIH) to lock-up depth and then tractor was activated from that depth to extend the reach of CT. At total depth (TD), the tractor was isolated and de-activated by dropping steel ball. The wells were acid stimulated while pulling-out-of-hole (POH). Pre-flush was pumped while RIH at low pumping rate to avoid activating tractor before lock-up depth and after lock-up, pre-flush was pumped through tractor to activate the tractor.
This paper outlines the tractor characteristics, matrix acid stimulation jobs design parameters, detailed operational data captured and the learning curve achieved during job execution.

Abstract
As part of the reservoir monitoring effort in Field X (Offshore East Malaysia), five oil producers were deployed with double-ended fiber optics cable across reservoir sections and permanent downhole gauges (PDG). Each well has between 2 to 4 zones. This has enabled various distributed temperature sensing (DTS) benefits such as gas-lift monitoring, well integrity, zonal-inflow profiling, and stimulation job evaluation, etc. This paper demonstrates and discusses the approach of incorporating both DTS & PDG data in Well B-1 to intrepret temperature signatures andanomalies during recent tubing-integrity tests, matrix acidizing and post-job production performance. Well B-1 is a gas lifted well that consists of three zones, and its production has been declining over years due to potential formation damage during drilling and fines migration issue. Hence, Well B-1 has been selected for matrix acidizing treatment to enhance the productivity. Prior to execution of the acidizing job, several conformance jobs such as tubing-integrity tests, injectivity test, and tubing pickling were performed. A baseline temperature was acquired to assist in the evaluation.
Due to operational challenges, the DTS data transmission wasn't acquired in real-time. However, each event's temperature profile has been studied thoroughly against the actual event schedule. Some significant findings are i) completion accessories effect (feedthrough packers) creates temperature anomalies, and ii) several leak points detected mainly between two upper zones where there was significant cooling effect due to injected fluid. The first-stage main treatment was conducted focusing on Zone 3. Due to leak points between the two upper zones, Zone 3 didn't get the designated main treatment volume. Second-stage main treatment, Zone 1 & 2 were treated together due to time constraint unlike Zone 3.
Post job production temperature profiles showed significant changes in the flowing temperature slope compared to pre-treament profile where there is an increase in overall wellbore temperature indicating increase in liquid volume and Zone 2 indicating higher Joule-Thompson cooling effect (more gas production).

Published: November 2020

Abstract
Proper selection of the drilling parameters and dynamic behavior is a critical factor in improving drilling performance and efficiency. Real-time monitoring allows the driller to avoid detrimental drill string vibrations and maintain optimum drilling conditions through periodic adjustments of various dynamic control parameters (such as weight on bit, rotary speed, circulation rate). However, selection of the appropriate parameters is not a trivial task. A few iterations in parameter modification may be essential before the desired target rate of penetration (ROP) is obtained; however, the final result may not be optimal yet. Therefore, the development of an efficient artificial intelligence (AI) method to predict the appropriate control parameters is critical for drilling optimization.
The AI approach presented in this paper uses the power of optimized Artificial Neural Networks (ANN) to model the behavior of the non-linear, multi- input/output drilling system. The optimization of the model was achieved by optimizing the controllers (combined Genetic Algorithm, GA and Pattern Search, PS) to reach the global optima, which also provides the drilling planning team with a quantified recommendation on the appropriate optimal drilling parameters. Development of the optimized ANN model used drilling parameters data which were recorded real-time from drilling practices in different lithological units. Representative portions of the data sets were utilized in training, testing and validation of the model.
The results of the analysis has demonstrated the AI method to be a promising approach for simulation and prediction of the behavior of the complex multi-parameter drilling system. This method is a powerful alternative to traditional analytic or real-time manipulation of the drilling parameters for mitigation of drill string vibrations and invisible lost time. The utilization can be extended to the field of drilling control and optimization, which can lead to a great contribution of 73% in reduction of the drilling time.
This work demonstrates the capability of the optimizing controller (combination of GA and PS) to improve the efficiency and accuracy of the conventional ANN for drilling optimization.

Authors: Mehran Fatemeh , Didanloo Ali 
Published: November 2020

Abstract
The super-giant field under study is one of largest oil producers in Middle East and been producing for more than 50 years from a multilayered carbonate reservoir. Long-term sustainability of production of the field is a key mission for the field operator and national oil company, considering both productivity and recovery of the field. Gas lift has been considered as an effective and economically feasible method to increase production of the wells and as a solution to revive the closed wells and to maintain the production of flowing wells.
Prior to full field implementation, a gas lift pilot has been initiated in the field. The objective of the pilot is to collect further essential information and evaluate the challenges prior to the full field implementation.
At the well scale, managing the well lift rate allocation, monitoring the performance of gas lift valves and running diagnostics, and optimizing the production rate are the main challenges for the gas lift pilot. At the full field network level, the backpressures of the lifted wells are affecting the production of the other wells producing naturally.
A commercial three-phase flow simulator was used to build the well models as well as the pilot network, with certain boundary conditions to develop a scalable solution to enable the operations and headquarters teams to provide a timely solution to the mentioned challenges. To integrate all inputs from various disciplines, the information from the monitoring activities and from reservoir saturation and production logging tools in addition to well test data and gas lift surveys was used to develop the solution.
The gas lift management solution was evaluated in the pilot area to diagnose the gas lift valves, validate well tests, optimize gas lift allocation, enhance well production, and perform field-wide production optimization The solution also reveals gas lift candidate wells with the potential to increase the production and directs redistribution of the lift gas in the pilot area to minimize gas utilization.
Additionally, to introduce scalable solution which can be utilized at very large wells count, automation of the workflow process has been considered to provide efficiency for engineers which will get advise from the solution.
Data While Tripping DWT: Keeping the Light on Downhole

Published: November 2020

Abstract
The objective of this paper is to discuss and outline the invention of the data while tripping (DWT) device, why it was developed, the development process, introduction to the market, and proven value for the end user.
A ‘Fail fast’ and ‘Test to Failure’ approach was taken where 3-D printing, simple prototypes, and components testing was performed before building gradually more sophisticated prototypes, all of which were tested to destruction. Based on learnings, a final test version was built and tested to 60 times the customer's requirements in a controlled environment.
The DWT device was deployed in the fall of 2019 on two offshore rigs in the North Sea for final prototype testing. This gave the basis for refinements leading up to the commercial version of the DWT device, as well as proving the conceptual value of the device; no people required in the red zone while tripping a wired drill pipe string, continuous downhole along string pressure measurements, continuous logging while tripping utilizing bottomhole assembly (BHA) tools, and continuous down hole and along string data input for automated drilling applications. Additionally, considerable time savings were proven.
The concept of being connected to a wired drill string during tripping operations has been on the industry's wish list for years. The lack of this technology has, on many occasions, been a showstopper for selecting wired drill pipe for drilling operations. The introduction of the DWT device has shown to be a success for both proving the value of deploying wired drill pipe (turning the lights on downhole) as well as staying connected to the downhole network while tripping (keeping the lights on downhole) – both systems enabling data flow without mud flow.
