IIoT and Analytics Helping Independent E+P Firms to Optimize Oilfield Operations

ARC has been blogging for a few years now about how IIoT-enabled solutions can help owner-operators, independent E&P players and other oil & gas stakeholders can put them on the path towards digital transformation and operational excellence. Most of these opined blogs have focused on how rotating equipment such as pumps, compressors and turbines can be optimized to improve production, improve efficiency, increase asset availability and/or reduce unplanned downtime. A few of those blogs even focused on well optimization and developing the digital oilfields of today.

ARC was briefed early this year by a firm, ReStream Solutions, that is employing analytics and real-time monitoring services (via a SaaS model) to focus on LOE (lease operating expenses) and production optimization as it relates to chemical injection to address problems of paraffins (big problem in Permian and Eagle Ford basins), corrosion, scaling, bacteria, etc. found in the wells that impact flow assurance. They provide a hardware module and software designed to make wells and leases more profitable by lowering the # of workovers required as well as automating and optimizing the amount of chemicals injected.

Traditionally, chemistry treatment regimes are determined in off-site labs and in a very static process with limited to little follow-up analysis which does not provide real-time visibility to evaluate chemistry performance. As a well matures and hydrocarbon/produced water ratio shifts and reservoir pressure declines, original chemistries and dosages are no longer valid and it can lead to over dosing which is expensive (something few companies can afford nowadays) and can potentially impact the life of well(s) as well as health of production equipment over time. The basic approach employed is to first collect data across fluid chemistries, well dynamics, reservoir characteristics, and equipment operation. Second to use proprietary software to identify problematic conditions, correlated variables and stimuli-response profiles. Third, after employing analytics then automate corrective actions to maximize asset performance efficiency and provide insights into critical best management practices.

The system relies on a plug and play sensor suite providing real-time monitoring via remote connectivity using on-board cell modem and SATCOM communication for LOE tracking and optimization.  They can even provide visibility into offset wells and monitor and measure impact of proximate well and any fracking that may be impacted and can provide root-cause analysis. Data collected in field is uploaded to AWS Cloud daily or every other data and real-time monitoring and identification of problem causers via machine learning. ReStream believes their real value lies in their deep domain expertise since each formation or even field/play has its own composite well conditions and characteristics that can vary greatly even in the same geographic area. According to the company, some of the benefits it provides include protecting and optimizing equipment, maximizing well productivity, in some cases – through well communication and chemistry was able to bring some wells back to stability and increase production, helped some customers identify optimum SOPs and work processes, and validate the performance of both employees and the process.

ARC continues to recommend that owner-operators and independent E&P firms consider technologies, solutions and services that may help them improve their operational performance, lower costs and/or improve productivity and collaboration of its employees and/or ecosystem of partners.
