Some well-testing operations are executed by performing multiple runs in hole using slickline and coiled tubing (CT). A technology has been developed that combines many of these operations, including contingency stimulation activities, into one run. A project spearheaded by ExxonMobil, Shell, Chevron, and the Southwest Research Institute (SwRI) has been established to advance separation technology through improved testing methods and collaboration between users and suppliers. The simplest way to measure return on investment for an offshore water treatment system is to determine whether using the system actually reduces the risk of paying a fine for violating water pollution laws.
A subsea water-treatment system designed to leverage space availability, steady temperatures, lower bacteria levels, and other natural benefits of the seabed environment was successfully installed during pilot testing at the Ekofisk field offshore Norway. This paper describes the design, testing, installation, and performance of the first fully completed well using an intelligent inner completion inside an uncemented liner with openhole packers for zonal isolation.
The projects are intended to accelerate the development and commercialization of treatment technologies to reduce waste water that is being injected into disposal wells and increase water supplies for reuse. 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.
Earthquake in Cushing, OK -- home to the largest oil storage facility in the world -- leads to further regulatory action on disposal wells in the area. Research and development firm Battelle is working on a new induced-seismicity study that aims to help wastewater disposal well operators in Ohio stay on the good side of state regulators. Industry regulators in Oklahoma have rolled out broad new restrictions on more than 600 disposal wells as part of the largest action of its kind taken in response to earthquakes. A surge in earthquakes tightly clustered in southern Kansas that followed the large increase in produced water injections prompted the state to cut the daily limits on disposal wells in that area to see if that will help solve the problem.
In the complete paper, three stages of review have been combined to find out the applicability of the most-feasible improved-oil-recovery (IOR) methods in North American unconventional reservoirs. The US Energy Information Agency reports that the country is seeing petroleum exports rise across the board and notes serveral drivers for this trend. This paper describes functional water-treatment steps that target the most common removal of suspended solids and oil or condensate from Produced-water (PW) and flowback-water (FW) for recycling or disposal operations. The discrepancy between crude and natural gas prices and estimates of increasing natural gas reserves are driving companies to study small-scale gas-to-liquids plants that can tie in multiple sources or stranded gas for a greater profit.
A professor who the EPA charged with reviewing its 2016 study on hydraulic fracturing’s possible drinking water impacts shared her observations on the flawed process that led to the agency’s final conclusion. With the API and a multi-operator group passing separate programs aimed at reducing methane emissions, the discussions on what defines an acceptable level of regulation continues within the industry. The US government is working on regulations to reduce oil industry methane emissions by more than 40% over the next 10 years. The simplest way to measure return on investment for an offshore water treatment system is to determine whether using the system actually reduces the risk of paying a fine for violating water pollution laws.
Petrofac continues working relationship with UAE following contract awards for Dalma Gas Development project. Just like Houston’s summer heat, corrosion of metal surfaces will occur—whether you like it or not. To help you better understand corrosion, these papers describe using water surveys in a production/injection plant, testing the effectiveness of mitigation, and data evaluation using machine learning. At a water treatment plant for an onshore oil field in northern Germany, formaldehyde injection was started in 2015 as a biocide. The goal of this study was to understand the chemical parameters and microbial distribution in the water system and whether formaldehyde injection was effective.
Approved in October, the Flow Measurement Technical Section will help engage the greater SPE technical community in flow-measurement-related issues and technologies. It will cover the full spectrum of flow measurement, including single-phase and multiphase flow. At a water treatment plant for an onshore oil field in northern Germany, formaldehyde injection was started in 2015 as a biocide. The goal of this study was to understand the chemical parameters and microbial distribution in the water system and whether formaldehyde injection was effective. To facilitate testing and comparison of products that attenuate microbially influenced corrosion under field conditions, a method using microorganisms from a low-tide, anoxic North Sea sample was developed that allows corrosion measurements to be made for corroding biofilms grown on steel surfaces.
Layne Water Midstream has amended its agreement with the Texas General Land Office to gain exclusive right for reuse and disposal of produced water in the Delaware Basin. As Permian production ramps up and saltwater disposal well capacity is pushed to its limit, companies see a need to develop collaborative, commercially viable methods of handling produced-water volumes. If reuse remains at its current rate of only 15%, operators could face a $30-billion tab.
