Guest Editorial Several advances have recently taken place in operators’ control rooms, writes Jason Urso of Honeywell Process Solutions. But an even more sophisticated control room is right around the corner.
Talent and Technology Solomon Associates’ Bill Glasscock says energy operations have begun employing a highly data-driven staffing assessment approach within the context of the business process.
Proppant Goes to Extremes Two large proppant makers have rolled out a new class of ultraheavy proppant built to stand up to the extreme stresses found on the frontiers of deepwater exploration.

Searching for Opportunities in Environmental Trouble Polluted streams in Pennsylvania could provide a source of water for hydraulic fracturing and help prove a new way to clean up waterways contaminated by coal mine waste.
Displacing Diesel: The Rising Use of Natural Gas by Onshore Operators Seizing on historic margins in domestic prices, North American oil and gas companies are increasing their efforts to use more natural gas and less diesel fuel to power their field operations.
Bit Technology and Bottomhole Assemblies
Martyn Fear, SPE, Vice President, Drilling and Completions, Husky EnergyIn previous editions of this feature, I highlighted the industry’s need for capability improvement in applied drilling optimization and we have discussed the gaps in people (knowledge), process (workflows), and equipment or technology that remain to be closed before true drilling optimization can be said to be occurring.
Torsional Dynamics and Point-the-Bit Rotary-Steerable Systems Torsional dynamics can be extremely damaging to downhole drilling tools and can significantly affect drilling efficiency. The effort to prevent this phenomenon has led to the development of various downhole mitigation tools, improved bit technologies and bottomhole-assembly (BHA) designs, and better management of drilling parameters. This paper outlines two lesser-known types of torsional dynamics observed while drilling interbedded carbonate formations in the Middle East with the [...]
Unconventional Polycrystalline-Diamond-Bit Design Allows Significant Performance Gains This paper discusses the design, manufacture, and application of a contiguous blade of polycrystalline diamond (PCD). This bit has full-length, contiguous PCD coverage, without gaps between cutters on each blade, as in a conventional PCD-compact (PDC) bit design. The implementation of this bit represents a step change in bit design. Drill-Bit Damage The traditional view has been [...]
A Geosteering Success Story From the North Sea The Nini East field represents a significant drilling challenge. The target is a post-depositionally remobilized sand reservoir with a thickness of 2‒15 m. None of the standard well-placement methods or current mapping tools was a suitable solution for the well objectives. A field test of the next-generation bed-boundary mapping tool was launched to geosteer two [...]
Syed A. Ali, SPE, Technical Advisor, SchlumbergerProduced water is an inextricable part of the oil- and gas-recovery process, and it is by far the largest-volume waste stream associated with oil and gas recovery.
Cyclic-Production-Scheme Performance Evaluated Using Reservoir Simulation Many strategies have been implemented to mitigate the problem of high water-production rates seen in mature fields. One of these is the cyclic-production scheme (CPS). This strategy, which requires alternately shutting and flowing wells with high water cut over a predetermined time, enhances sweep efficiency and pressure maintenance and reduces water-handling costs. In a reservoir-simulation [...]
Comparing North Sea and Deepwater Gulf of Mexico Produced-Water-Treating Systems In terms of platform technologies and extraction strategies, there are fundamental differences between the North Sea and the deepwater Gulf of Mexico (GOM). We consider these systems in light of best practices in water-treating-system design and consider the reasons for deviation from those practices. This process provides insight into the design of water-treating systems in [...]
Produced-Water-Reinjection Design and Uncertainties Assessment Produced-water reinjection (PWRI) is an important strategy for deriving value from waste water, but its implementation can face challenges related to injectivity and safety issues. The first objective of a PWRI-design study is to supply water-quality specifications, and the second is to supply injection-pressure specifications. The objective of this paper is to detail how water [...]
Production and Facilities
Hisham Saadawi, SPE, Vice President of Engineering, ADCOTwenty-five years after the Piper Alpha disaster in the North Sea, process safety continues to be a subject of great interest to the oil industry.
Implementing a Process-Safety Program Between 2006 and 2009, Petronas Carigali embarked on a process-safety program driven by concerns over an increasing trend of process-related incidents. The program focused on defining explicit process-safety expectations and then putting in place the required processes to intensify implementation and mandatory compliance. Some 3–4 years into the program, tangible improvement can be felt across the organization. [...]
Abnormal-Situation Management in Offshore Operations The Abnormal Situation Management (ASM) Consortium performed a root-cause analysis on 32 incident reports gathered from public documents and member companies. The analysis identified common failure categories and manifestations in these incidents. Consequently, the consortium completed three case studies on potential deployment solutions: one supporting better shift-handover communication, a second supporting better alarm-flood situations, and [...]
The Business Case for Process Safety Over its 27-year history, the Center for Chemical Process Safety (CCPS) has observed that the first step toward implementing a strong process-safety-management program is obtaining top-management commitment. The CCPS has learned that communicating the business case for process safety is an important part of the process of obtaining this commitment. Using a fictional incident as [...]
Reserves / Asset Management
Delores James Hinkle, SPE, Retired, Marathon OilMembers of SPE continue to share valuable and useful information through the more than 90 papers on reserves and asset management presented at various meetings, symposiums, and workshops this past year.
Recently Released Guidelines Supplement Petroleum Resources Management System The Guidelines for Application of the Petroleum Resources Management System (AG) document was issued in November 2011 to accompany and support the Petroleum Resources Management System (PRMS). The AG updates the 2001 document Guidelines for the Evaluation of Petroleum Reserves and Resources. This document will assist reserves evaluators throughout the world in understanding PRMS and [...]
Integrated-Asset-Modeling Approach for Reservoir Management on North Slope An integrated-asset-model (IAM) approach has been implemented for the Alpine field and eight associated satellite fields on the western Alaskan North Slope (WNS) to maximize asset value and recovery. The IAM approach enables the investigation of reservoir- and facilities-management options under existing and future operating constraints. The technology used for managing the fields consists of [...]
Integrating Well, Reservoir, and Facility Management Improves Field’s Production A carbonate field developed by Petroleum Development Oman is one of the largest fields in the Sultanate of Oman and has been running for more than 4 decades. An integrated wells, reservoir, and facility management approach has been implemented to create more focus and discipline with the aim of achieving an efficiently monitored and controlled asset and [...]
Probabilistic and Deterministic Methods: Applicability in Unconventional Reservoirs Reserves- and resources-evaluation methods in unconventional reservoirs are different from those for conventional reservoirs. Depending on the phase of the resource play, a deterministic, probabilistic, or hybrid method may be required, with the most effective method evolving from deterministic toward probabilistic as the resource play moves from the early phase to the mature phase. To [...]
