The perceived impact of chlorine dioxide (ClO2) on the corrosion of steel used in the oil patch has been a controversial issue for many years.   Although a few studies on this issue have been published, those results have been contradictory. As concerns surrounding this issue continue to be raised, a systematic study has been undertaken to understand the corrosive effects of ClO2 towards steel in various produced waters.  Research shows that the baseline corrosion rate of untreated produced water is related to TDS, with other factors being involved, such as the presence of H2S and iron.

With the increase in activity in the Delaware Basin, preparing wells for the pressure spikes seen from offset fracs is crucial in order to maintain safe operations.  It is important to take risk and economics into account when deciding how to prep a well. Most importantly, historical data should be factored into the decision making process and used to build the program guidelines.  Factors that should be accounted for are artificial lift type, surface equipment ratings, producing interval, frac azimuth, and 
relative distance and position to the well being fractured.
 

The purpose of this project is to conduct a Dynamic Filtration Test to Investigate the Effect of Preformed Particle Gels (PPGs) on Un-swept, Low-Permeable Zones/Areas. A filtration test is a simple means of evaluating formation damage. This work use schematically dynamic filtration test experiment design apparatus to carry out the various filtration test experiments. It use different core samples, various brine concentration, and various gel types.  The permeability   of each sandstone core samples is calculated before and after the filtration test. Experiments are still being observed.

There is a growing need for energy throughout the world and this increase in demand for energy has now also put a strain on the current sources of energy. In the process of oil/gas production, there are large amounts of water released into the atmosphere as well as into the ground or soil. This water contains chemicals such as Sulphur and Nitrogen oxides, Bitumen, Calcium, Base oil, and Sodium. It is commonly referred to as “wastewater” and is disposed of. The goal of this project is to investigate the possibility of acquiring energy from this wastewater.

Success in the oil and gas industry comes with effectively juggling four key elements: money (made or lost), risk, technical capability, and competition. Information is key to managing this process. Data sharing is the controlled process of providing information to and obtaining information from your competitors in such a manner to ensure your success (and theirs, as well). When well executed, data sharing can help one optimally find and develop highly profitable properties with minimal risk for failure.

Autonomy- the freedom from external control. It is unceasingly transforming the world around us, bringing opportunities to revolutionize industries and expand frontiers. The Saildrone is an unmanned surface vehicle developed for long range, long term, ocean data gathering. In the project we looked at data obtained by the EK80 single beam sonar device and GPS transponder that outfitted the Saildrone which explored the Bering Sea.

Paraffin mitigation has been the subject of many case studies involving various chemical blends, treatment frequencies and in some cases down hole tools. All with varying degrees of success, most leave the operator left managing the issue rather than mitigating it. Struggling to find an effective solution for wells in Upton county, Diamondback set out to find a solution beyond the typical conventions. Establishing a systematic approach, Diamondback found a solution that mitigates paraffin formation, prolongs well run times and ultimately reduces operating expenses for Diamondback wells.

High disposal costs and a limited availability of freshwater have led many industry players in the Permian Basin to reclaim produced water and use it in subsequent well fracturing. This reclamation process typically involves pumping produced water from numerous production batteries to a central location where it is placed in storage in large surface impoundments until such time that it is needed in fracturing operations.

The presentation opens by highlighting the Industry’s responsibility for environmentally safe water disposal, then discusses the pros and cons of Vendor Owned / Managed versus Company Owned / Operated water systems. Design considerations for the holistic water management system are as follows:
 
•         System Capacity and Layout : Evaluate not only current needs, but future needs. Design for the “worst” case scenario, by building the system above current volumes and determine what expansion will be required for the future drilling program.

A new sulfur removal process utilizing traditional iron oxide in a very unique way.  The process produces a highly effective technology to completely remove H2S and eliminate acid gas disposal, liquid chemical management and other environmental challenges.
