The Opioid Epidemic: Postoperative Pain Management Strategies in Orthopaedics
Authors: Labrum Joseph T. , Ilyas Asif M. 
Published: August 2017

➢ Orthopaedic surgeons are currently estimated as the fourth highest opioid prescribers across all medical specialties. Preliminary research aimed at quantifying postoperative opioid utilization and prescribing patterns indicates that orthopaedic surgeons are inadvertently overprescribing opioids in the postoperative period.➢ Preoperative history gathering and communication are vital to a successful postoperative pain experience. Patient education on surgical intervention, prescription opioid misuse risk factors (smoking, preoperative prescription opioid use, and so forth), and maintenance of preoperative opioid naiveté can aid a patient in avoiding prescription opioid misuse.➢ Multimodal analgesia, in addition to a patient-centered prescription opioid regimen, is needed to address diverse pain pathways, to mitigate postoperative pain, and to minimize opioid utilization.➢ Use of prescription opioid universal precautions, standardized opioid taper regimens, tamper-resistant opioid formulations, and rapid cessation of opioid use in the postoperative period are strategies that can aid in monitoring and ensuring a successful and safe discontinuation of prescription opioid use following orthopaedic surgery.➢ Pain inherent in many orthopaedic surgical interventions, current limitations in effective analgesic treatment modalities, and growing awareness of the extensive adverse effects and nontherapeutic uses of opioids make strategies for postoperative pain control a highly complex problem that requires physicians to adopt patient and/or technique-specific approaches.

E&P Notes
Researchers: Models Overstate Technology Impact, Understate Location Impact for Unconventional Wells
Joel Parshall, JPT Features Editor
The role of new technological improvements in the increasing productivity of tight oil and shale gas wells is likely being overestimated because of models that inadequately consider the influence of drilling in reservoir core areas, a pair of researchers at the Massachusetts Institute of Technology Energy Initiative (MITEI) have said in a new paper.
With the steep fall in oil prices since late 2014, field operators are drilling fewer wells and have shifted their targets to only the most prospective acreage. The oil industry’s often well-publicized gains in well productivity significantly reflect the impact of drilling and hydraulic fracturing operations focused on reservoir “sweet spots,” MITEI’s Justin Montgomery and Francis O’Sullivan write in a paper in Applied Energy.

Drilling Boom Goes Flat
Stephen Rassenfoss, JPT Emerging Technology Senior Editor
Growth in the US rig count stalled in mid-July, in what could be a sign of things to come.
After doubling over the previous 12 months, the rig count remained flat, slipping to 949 as of 11 August, according to the Baker Hughes Rig Count.
But surveys of industry insiders by the Federal Reserve banks of Dallas and Kansas City see that rally running out, with shrinking spending on capital expenditures (Capex) and drilling.
“We see the expected Capex and expected drilling number are still positive. It is a lot less positive than in the first quarter and certainly in the fourth quarter of last year,” said Chad Wilkerson, the branch executive and economist at the Kansas City Fed’s Oklahoma City branch, adding, “Leveling seems to be the story.”

US Daily Oil Production To Break Record in 2018
Joel Parshall, JPT Features Editor
Average total crude oil production in the United States is expected to reach a record level of 9.9 million B/D in 2018, the US Energy Information Administration (EIA) said in its latest forecast.
The projected output would surpass the 9.6 million B/D that the US produced in 1970. The forecast said that total US crude oil production will average 9.3 million B/D this year, an increase of 500,000 B/D from 2016.
Most of the production growth from June through the end of next year is expected to come from tight rock formations in the Permian region of Texas and from the Federal Offshore Gulf of Mexico (GOM).

IEA: US May Be Top LNG Exporter by 2022
Trent Jacobs, JPT Digital Editor
The US may become the global leader in liquefied natural gas (LNG) exports, according to a new report by the International Energy Agency (IEA). To ascend to the top spot, US LNG shipments must surpass today’s leading exporters, Australia and Qatar.
The IEA called US LNG a “catalyst for change” and highlighted how production from tight shale gas fields is transforming the world’s natural gas marketplace. The Paris-based organization also said the country’s exports will help fuel economic growth in developing countries.
Technology Focus: Drilling Systems Automation and Management (September 2017)
Authors: Macpherson John 
Published: August 2017

Technology Focus
The drilling industry is changing. Equipment providers, service companies, and drilling contractors are redefining the boundaries of their business interests, and these boundaries are evidently quite porous.
Over the past year, workshops and symposia have made it clear that consideration of data and digitalization plays an important role in transforming companies in the drilling industry. Systems automation requires a digital backbone and offers significant performance, cost, and safety benefits. It is not surprising, therefore, that companies are exploring data-analytics techniques and drilling systems automation and that this exploration will define the new boundaries (if any remain) between segments of the well-drilling and -completion industry.
The selected papers on drilling systems automation and management pick out various themes in this transformation. One paper deals with close collaboration between operator, drilling contractor, and service company in automating aspects of a drilling operation. Another paper deals with combined modeling and real-time surveillance and the required awareness by rig crews when operating rig-control systems. The third selection deals with the propagation of uncertainty in drilling and the development of a strategy to optimize performance against risk.
These papers, and the alternative papers, illustrate the integration and collaboration that are necessary for drilling systems automation and management, which is transforming the traditional roles of equipment providers, service companies, and drilling contractors.
One story that is somewhat obscured in the selected papers is that human-factors engineering will play an increasingly important role in our industry as we take care in specifying the role played in automated systems by crews both on the rig and remote to the rig.

Laboratory Testing and Prediction of Asphaltene Deposition in Production Wells
Authors: Wilson Adam 
Published: August 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper OTC 27884, “Laboratory Testing and Prediction of Asphaltene Deposition in Production Wells,” by Kosta J. Leontaritis, SPE, and Efstratios Geroulis, SPE, Asphwax, prepared for the 2017 Offshore Technology Conference, Houston, 1–4 May. The paper has not been peer reviewed.

During primary oil production, when the thermodynamic conditions within the well tubing lie inside the asphaltene-deposition envelope (ADE) of the produced fluid, flocculated asphaltene particles could start being deposited on the tubing wall, causing a restriction in the tubing inner diameter that results in loss of production. This paper presents a methodology that begins by determining the ADE in the laboratory. Moreover, asphaltene-deposition rates for the tubing conditions can be measured using high-pressure/high-temperature coaxial-cylinder technology.
In-Situ Asphaltene Testing
At some thermodynamic states, asphaltenes exhibit a behavior called flocculation—that is, asphaltene particles or micelles aggregate or flocculate into larger particles or flocs. The locus of all thermodynamic points in a phase diagram at which flocculation occurs is called the ADE. Accurate measurement of asphaltene solubility at in-situ conditions inside the ADE is extremely difficult. Many asphaltenic reservoir fluids exhibit irreversible asphaltene flocculation. This means that, once the upper ADE boundary is crossed, some of the asphaltenes will not deflocculate and go back into stable suspension by simply reversing the thermodynamic path.
The spectrophotometric near-infrared (NIR) onset method uses the observation that there is a sharp increase in light absorption or attenuation in the NIR region of the electromagnetic spectrum at the onset of asphaltene flocculation.
Transmittance of light through a sample of asphaltenic oil has also been used to detect the onset of asphaltene flocculation. There is a sharp decrease in the transmittance of NIR light through a sample of asphaltenic oil at the onset of asphaltene flocculation.
Along with the spectrophotometer, an NIR imaging system is also used in the attempt to decipher the asphaltene behavior of a fluid.
One can change the thermodynamic conditions in the vessel containing the sample and obtain the oil’s ADE. State-of-the-art high-pressure/high-temperature imaging technology is routinely used in the laboratory to detect asphaltene particles very clearly upon isothermal pressure depletion. The asphaltic heavy-phase-formation phenomenon is indicated in the images to be a consequence of many asphaltene particles forming, aggregating, and settling in the NIR cell under the prevailing thermodynamic conditions. This indicates that the asphaltene-phase behavior responsible for asphaltene-induced formation damage and asphaltene-deposition problems takes two forms—asphaltene flocculation into larger particles or heavy-asphaltic-phase separation.
A transboundary aquifer of potential concern in Southern Africa
Authors: Gomo Modreck , Vermeulen Danie 
Published: August 2017

Abstract
Tuli Karoo transboundary aquifer (TBA) is shared between Botswana, South Africa and Zimbabwe in the Southern African Development Community (SADC) region. The TBA provides groundwater resources for various economic activities. Irrespective of the value offered by this TBA, there is very little research that has been conducted to improve understanding of the physical system and potential cross-border impacts that can result from exploitation of the aquifer. In the wake of this limited research, this paper uses theoretical background and conceptual understanding to highlight some of the activities that have the potential to cause conflicts within the TBA. This article presents and discusses the current hydrogeological conceptual understanding of the Tuli Karoo TBA system, social and economic activities and their potential impacts on the TBA. Based on the discussions of various scenarios, it can be argued that the potential for groundwater cross-border flow and impacts exist within the TBA. With the ever-increasing and competing demands for fresh water and unpredictable rainfall patterns in the region, the possibility of future conflicts cannot be ruled out. It is hoped that this study can assist in raising awareness about the need to address aspects of sustainable exploitation and management of the TBA.

Authors: Buurman Joost , Santhanakrishnan Deepak 
Published: August 2017

Abstract
Scaling up pilot projects providing continuous water supply to households in Indian cities has proved challenging. This study identifies opportunities and barriers in scaling up, in order to derive recommendations for bridging the gap between testing policy innovations and bringing projects to scale. We analyse pilot design, required resources, and drivers of stakeholders, institutions and the environment for a case study in Karnataka and find a wide range of factors that affect adoption of 24/7 water supply. Upscaling should be tailor-made for each area, which requires space, scope and capacity to be created for local involvement.
