Identifying and Exploring the Informational and Emotional Support Needs of Primipara Women: A Focus on Supportive Communication
Authors: Fakhraei Romina , Terrion Jenepher Lennox 
Published: October 2017

ABSTRACTPrimipara women may require greater informational and emotional support than multipara women. Supportive communication, including informational and emotional support, can help to build a strong caregiver–patient relationship and can alleviate the difficulties associated with first-time birth. The objective of this study was to explore first-time mothers’ experiences of labor and birth. Three hundred primipara women completed self-report questionnaires. Qualitative analysis of one open-ended question about the women’s experience was conducted. Nine themes emerged from the data. Eight themes reflected informational and emotional support needs, whereas the final theme reflected instrumental support needs. The study concluded that informational and emotional supports are important factors of supportive communication and influence the birthing experience of primipara women.

Guest Editorial: Innovation Will Drive Shale Survival
Authors: Rao Vikram

Guest editorial
That which does not kill us, makes us stronger.—Friedrich Nietzsche, 1889
The petroleum industry has seen up and down cycles. In the past, they have been driven by politics, such as in the case of the Arab oil embargo, or supply and demand imbalances, driven primarily by unrest and recessions. The creation of OPEC dampened the latter. But this time it is different. Shale, a new, abundant source of oil and gas has more than halved oil prices. It has kept prices low for nearly 3 years, and threatens to do so for many more. This threat will be realized if the industry can be profitable at sustained prices below $40/bbl.
History informs us that this is likely. The last long-lived drop in activity roughly spanned the decade from the mid-1980s to the mid-1990s. The rig count was more than halved from 1984 levels for well over a decade. This trailed the oil price drop, which nearly halved from 1980 to 1985, and stayed that low for over a decade. For the industry to survive, oil companies needed lower production costs and the service companies still needed to make a profit at low activity levels. This is precisely the situation today in shale oil and gas. On that occasion, the industry responded with innovation in technology and, to a lesser degree, in business models. This too will happen today.
Horizontal Wells and More
Horizontal wells, possibly the single greatest productivity improvement innovation in the business, came into their own during that earlier downturn. They had been known for decades, but this period produced additional key enablers for economic construction. Desktop 3-D seismic interpretation allowed for placement in the most productive portions of reservoirs. Polycrystalline diamond composite (PDC) bits improved drilling rates. Measurement while drilling (MWD) gave crucial position information on the fly. Later, MWD systems allowed formation evaluation, which was prohibitive with conventional logging methods in hole angles greater than 60 degrees. At this point, drillers knew where to be, and where they were, in 3-D and geologic space.
Shale Water: Turning Dirty Produced Water Into Fresh Water and Salt To Sell
Authors: Rassenfoss Stephen

Turning Dirty Produced Water Into Fresh Water and Salt To Sell
In a little more than a decade, the way water is supplied for fracturing in the Marcellus play has gone from “a truck with a hose in the creek” to “a massive industrial system” for water transport and treatment.
The description was offered by Conrad Baston, general manager of civil design for Antero Resources, who has played a key role in a major example of the change: a $750-million system to transport, store, and convert produced water into fresh water for use in its operations in West Virginia and Ohio.
The first stage was the most expensive—$500 million spent on 200 miles of buried and temporary pipelines to deliver fresh water for fracturing and 23 large freshwater impoundments to ensure a ready supply of water to fracture ever-longer horizontal wells. The water delivered by the system since 2014 would have required 1.4 million truck trips, and it has also reduced the volume of water drawn from local streams.
Stage 1 was part of a larger industry trend. What comes next is different. It is a one-of-a-kind $275-million plant that will convert 60,000 B/D of dirty, high-salinity water into fresh water and salt when it is fully operational next spring.

Drilling Slowdown Sparks Water Trading
It is known that a well injecting a lot of water near a big fault can lead to earthquakes. The problem is, more often than not those faults are not known until after a tremor.
“There was a time in the Marcellus where nearly every barrel of water produced was needed for the next well fractured. And then drilling slowed and some operators were stuck with produced water and no well to put it in.
It was a costly problem to have. The obvious solution was hiring a lot of trucks for the long haul to Ohio where injection disposal costs $8-10/bbl. It was so bad that operators changed their ways and began seeking out competitors to take the water off their hands, said Joseph Frantz, vice president of engineering in Range’s Marcellus division, which was a big buyer.
In 2016, when Range reported reusing 99% of its produced water in the Marcellus, it bought enough from others to push that total to 141% of its produced water, exceeding its fresh water use for fracturing, according to the company’s website.
“It saved us a lot of money last year,” Frantz said. “It really came out of sharing, and helping each other out.” The volume of water selling has dropped as drilling has come back, but it is still going on, he said.
More trading with competitors with nearby wells could allow deals that reduce one the highest costs of water management—moving it. “For us the goal is to be as flexible as possible and able to move water around really cost effectively,” said Frantz.
While there are entrepreneurs trying to create water trading markets, Frantz said they worked directly with others to set up deals.
High-Performance Brine Viscosifiers for High Temperatures
Authors: Carpenter Chris 
Published: October 2017

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 183964, “High-Performance Brine Viscosifiers for High Temperatures,” by Peter J. Boul, Suhaib Abdulquddos, and Carl J. Thaemlitz, Saudi Aramco, prepared for the 2017 SPE Middle East Oil and Gas Show and Conference, Manama, Bahrain, 6–9 March. The paper has not been peer reviewed.
Many viscosifiers currently used in high-density solids-free reservoir drilling fluids (RDFs) and completion fluids (CFs) are incompatible with high-density brines or require the use of prohibitively expensive brines to achieve target densities. There is substantial commercial benefit to developing a brine viscosifier with a higher temperature tolerance than is currently offered. A supramolecular viscosifier package has been developed that uses noncovalent associations between additives to enhance the thermal resilience of divalent brine fluids. Static aging-test data indicate that the supramolecular viscosifier outperforms high-performance, commercially available starch/xanthan brine viscosifier.
Background
The exploitation of oil and gas reservoirs found at increasing depths and the development of horizontal and slimhole drilling have increased the demand for high-density solids-free RDFs, CFs, and workover fluids (WFs). The use of divalent brine-based drilling fluids and CFs in well sections with temperatures exceeding 260°F is limited because of degradation of the polymers used to viscosify the fluid and suspend drill cuttings.
Effective drilling fluids have numerous functions in well construction. They must have the physical properties required to carry cuttings from beneath the drill bit up the annulus of the well for separation at the surface. They must also provide cooling for the bit and be able to reduce-friction between the drillstring and the formation being drilled. This must be accomplished without damaging the formation. The inflow of fluids or solids from the drilling mud can cause formation damage, which can reduce the rate of penetration during drilling and can also decrease the rate of hydrocarbon production from a producing well.
RDFs, CFs, and WFs must be density-adjusted to provide the hydrostatic head to preserve the integrity of the wellbore walls and to prevent blowouts. Although drilling through much of the well can be accomplished with oil- or water-based fluids weighted by solid particles of such minerals as barite, the reservoir sections offer a different challenge because of the concern that these solids could plug pores in the formation and reduce hydrocarbon-flow rates. It is for this reason that operators look to brines to provide density in RDFs. Recently, research in nanomaterials has revealed the potential of low-solids nanofluids for the prevention of formation damage.
Horizontal Drilling With Dual-Channel Drillpipe
Authors: Carpenter Chris 
Published: October 2017

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 184683, “Horizontal Drilling With Dual-Channel Drillpipe,” by O.M. Vestavik and J. Thorogood, Reelwell; E. Bourdelet, Total; and B. Schmalhorst and J.P. Roed, DEA Deutsche Erdoel, prepared for the 2017 SPE/IADC Drilling Conference and Exhibition, The Hague, The Netherlands, 14–16 March. The paper has not been peer reviewed.
A new drilling method provides a solution for challenges encountered in drilling of long horizontal wells, incorporating a dual drillstring with a separate channel for the return fluid from the well. This arrangement enables managed-gradient drilling (i.e., to drill with a constant downhole pressure gradient that can be controlled to be nearly independent of the flow rate). The solution is similar to managed-pressure drilling (MPD) but differs in that the downhole pressure gradient is managed instead of the pressure at one depth in the well.
Introduction
The technology for drilling and completion of long horizontal sections has improved significantly in recent years. However, challenges such as hole c leaning, equivalent-circulating-density (ECD) control, and torque-and-drag reduction still exist. ECD is linked to hole cleaning and is often a limiting factor. Long-reach horizontal wells can also be limited by the torque and drag of the drillstring.
The dual-drillstring configuration has specifically been developed to provide solutions to these challenges, as follows:
Hole cleaning: Drill cuttings are removed from the bottom of the hole through a separate flow channel inside the drillstring.
ECD control: Managed-gradient drilling creates a constant downhole pressure gradient independent of the flow rate.
Torque and drag: A heavy-over-light fluid solution reduces torque and drag through buoyancy.
Fig. 1 presents a schematic of the drilling-fluid flow for this arrangement. The dual drillstring allows drilling mud to be pumped down the annulus inside the drillpipe, with the return flow up the concentric inner pipe. The system can be installed on a standard drilling rig. A topdrive adapter connects the rig’s topdrive to the top of the dual drillstring. The adapter contains a swivel that allows for pumping mud into the drillpipe annulus and for the return flow from the inner pipe to be directed back to the surface mud system. The lower end of the dual drillstring connects to a standard bottomhole assembly (BHA) by means of an inner-pipe valve, which contains entrance ports for the return fluid and isolates the well during pipe connections.
Production Pressure-Drawdown Management for Fractured Horizontal Shale Gas Wells
Authors: Wilson Adam 
Published: October 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 181365, “Production Pressure-Drawdown Management for Fractured Horizontal Wells in Shale Gas Formations,” by Ankit Mirani, University of Houston; Matteo Marongiu-Porcu, SPE, Schlumberger; HanYi Wang, SPE, The University of Texas at Austin; and Philippe Enkababian, SPE, Schlumberger, prepared for the 2016 SPE Annual Technical Conference and Exhibition, Dubai, 26–28 September. The paper has not been peer reviewed.
The primary objective of this study is to address all known causes of productivity declines in unconventional shale gas formations with horizontal multifractured wells and to develop
a fully coupled geomechanical/flow simulation model to simulate these production conditions. The model mimics the effect of depletion-induced in-situ stress variations on productivity by taking into account several phenomena, such as stress-dependent matrix and natural-fracture permeability and reduction in fracture conductivity because of fracture-face creep and proppant crushing, deformation, and embedment.
Model Formulation
Reservoir Matrix. The gas-storage mechanism in a shale gas reservoir is conceptually different from that of a conventional reservoir. Natural gas is adsorbed on the organic matter present in shales and, in some cases, on certain clay minerals. This adsorbed-gas layer further constricts the area for flow through the pore structure, thus reducing the effective pore radius. As the pressure in the pores reduces, gas is desorbed and the effective pore radius increases, resulting in an increase in the apparent matrix permeability. It has been suggested that desorption of methane might be partially responsible for the relatively long and flat production tails that have been observed in some shale reservoirs.
Fig. 1 shows the effects of different mechanisms on permeability evolution. Clearly, shale gas long-term performance forecasting will be affected severely if these effects are not properly considered.
Hydraulic Fractures. Hydraulic fractures are generally kept open and conductive by proppant. After exposure to confining stress for a long period of time, proppant can become deformed, causing degradation of its mechanical and physical properties. This leads to reductions in fracture width and fracture-pack permeability because of intermixing and plugging.
Additionally, the interaction between the proppant and fracture surfaces under the same confining stress can result in embedment, decreasing the fracture aperture and impairing conductivity.
