The SWP project is located in a mature waterflood undergoing conversion to CO2-WAG operations at Farnsworth, Texas, USA. Utilized CO2 is anthropogenic, sourced from a fertilizer and an ethanol plant. Major project goals are optimizing the storage/production balance, ensuring storage permanence, and developing best practices for CCUS.
This paper provides a review of work performed toward development of a 3D coupled Mechanical Earth Model (MEM) for use in assessment of caprock integrity, fault reactivation potential, and evaluation of stress dependent permeability in reservoir forecasting. Mechanical property estimates computed from geophysical logs at selected wellbores were integrated with 3D seismic elastic inversion products to create a 3D "static" mechanical property model sharing the same geological framework as the existing reservoir simulation model including 3 major faults. Stresses in the MEM were initialized from wellbore stress estimates and reservoir simulation pore pressures. One way and two way coupled simulations were performed using a compositional hydrodynamic flow model and geomechanical solvers.
Coupled simulations were performed on history matched primary, secondary (waterflood), and tertiary (CO2 WAG) recovery periods, as well as an optimized WAG prediction period. These simulations suggest that the field has been operating at conditions which are not conducive to either caprock failure or fault reactivation. Two way coupled simulations were performed in which permeability was periodically updated as a function of volumetric strain using the Kozeny-Carmen porosity-permeability relationship. These simulations illustrate the importance of frequent permeability updating when recovery scenarios result in large pressure changes such as in field re-pressurization through waterflood after a long primary depletion recovery period. Conversely, production forecasting results are less sensitive to permeability update frequency when pressure cycles are short and shallow as in WAG cycles.
This paper describes initial work on development of a mechanical earth model for use in assessment of geomechanical risks associated with CCUS operations at FWU. The emphasis of this work is on integration of available geomechanical data for creation of the static mechanical property model. Preliminary coupled hydro-mechanical simulations are presented to illustrate some of the key diagnostic output from coupled simulations which will be used in later work for in depth evaluation of specific risk factors such as induced seismicity and caprock integrity.
High-fidelity 3D engineering simulations are valuable in making decisions, but they can be cost-prohibitive and require significant amounts of time to execute. The integration of deep-learning neural networks with computational fluid dynamics may help accelerate the simulation process. Reducing a separation system’s footprint while increasing separation efficiency is demonstrated in an Oklahoma field trial. Reliable separation is becoming an enabling technology to help develop remote location resources and more difficult applications, such as heavy oil, produced water, sand disposal, and back-produced fluids in enhanced oil recovery. This paper provides details of comprehensive computational-fluid-dynamics (CFD) -based studies performed to overcome the separation inefficiencies experienced in a large-scale three-phase separator.
The chief upstream strategist of IHS Markit said in a recent presentation that oil exploration must improve its ability to deliver value and better communicate that value to the financial community. New ways of thinking about exploration opportunities are needed. Producers in Oklahoma’s newly opened Merge play are sitting atop a resource that rivals some major world gas fields and discoveries, Citizen Energy’s Geology CEO Greg Augsburger told the SPE Gulf Coast Section Business Development Group recently. The Austin Chalk play could go through a revival if the industry can view the formation through “a fresh set of eyes,” says EnerVest’s Tony Maranto. Dimethyl-ether (DME) -enhanced waterflood (DEW) is a process in which DME is added to injection water and, upon injection, preferentially partitions into the remaining oil.

Producers in Texas have claimed an economic victory with their transition to local sands that they once avoided using in horizontal wells due to their low-quality. Driven by a recovery in well completions and increased proppant loading per well, the market for raw fracturing sand is expected to grow by more than 4% annually through 2021, an industry research study says. Permian Basin producer Callon Petroleum is attributing its data-driven approach to a routine completions practice to improved proppant placement and higher oil production. Carbo Ceramics is making big strides in the use of ceramic proppant. Although Saudi Arabia has plenty of sand, it took some ingenuity by Saudi Aramco and Schlumberger to figure out how to use it effectively as proppant.
Billion-dollar valuations for these companies in the near future could become a reality. Frac water disinfection experts become De Nora service arm in the unconventional oil and gas market. Three papers selected from 2018 SPE ATCE look at the challenges and approaches to the treatment of increasing volumes of produced water. Sourcing water for hydraulic fracturing, and disposing of produced water, are constraints and significant cost items in the Permian Basin. Some of the produced water can be treated and reused by using a water life cycle approach.. Water management for unconventional projects continues to evolve at a rapid pace.
The pipeline system will have the initial capacity to deliver 150,000 B/D of crude oil to multiple delivery points, accessing local refineries and connecting to several downstream pipelines. The oilfield services and equipment sector, while optimistic, has not yet seen the effects of the improved oil price in the recovery of its overall business. An overview of some of the trends and issues related to water management for tight oil and gas are discussed, including environmental, sustainability, and legislative issues associated with water handling for hydraulic fracturing. An advisor at Newfield Exploration takes a closer look at the company’s water management operations in the Oklahoma STACK, as well as the lessons learned in its development. How Has the US Fracking Boom Affected Air Pollution in Shale Areas?
For employees to report on safety incidents, there must be a ‘just culture,’ where issues can be discussed freely and underlying causes investigated and corrected without fear of punitive actions. Companies in the petroleum industry, from exploration and production, to transportation, refining, and distribution, operate around the clock. This paper intends to raise awareness on the impact of fatigue in the petroleum industry and recommend a framework for fatigue risk management. Safety depends on developing a dedicated culture mind-set and mitigation of risks, from the planning and engineering phases to the work site. These papers selected by OGF technical paper editor Gerald Verbeek present various practices for reducing and eliminating the number of incidents.
