(2014022) TROUBLESHOOT ROD PUMPED WELLS USING TUBING FLUID LEVEL SHOTS

If no pump action, a recommended practice is to shoot a fluid level down the casing annulus and also shoot a fluid level down the tubing.   Distance down the tubing is determined by using the average acoustic velocity obtained from the casing shot.  DO NOT use the tubing average joint length to interpret the down tubing fluid level, because inside the tubing rod couplings are spaced at the length of the sucker rods.


 


Analysis of the acquired data can determine such things as: If there is a hole in the tubing.  Additional tubing back-pressure maybe required if tubing liquid was unloaded by significant amount of gas produced up the tubing.  Tubing pressure buildup measurement determines the amount of gas flowing up the tubing, tubing percent liquid, and the effectiveness of the dowhole gas separation. Difficult to interpret tubing shots may indicate that the well has “paraffined-up”.  Tubing shots acquired at uniform time intervals can show ineffective pump operation, where “pumping up” the tubing occurs too slowly. Down tubing fluid levels are effective tools when troubleshooting shooting a shut-in sucker rod pumped well suspected of having no pump action.

(2014023) THE ULTIMATE ROD STRING DESIGN PROCEDURE

Available sucker-rod strong design models calculate rod taper lengths that ensure proper operation without premature fatigue failures. Their common design problems are (a) defining the principle of taper length determination, and (b) calculating the true mechanical stresses along the string. The universally accepted principle of taper length calculations is to province the same level of safety against fatigue failure in each taper section. Mechanical loads and stresses, not he other hand, are found form highly approximate calculations in most of the design procedures. These loads, therefore, can greatly deviate from the true mechanical loads that would be measured in the rod string run in the well. The paper discusses the development of a novel procedure that estimates rods loads from the predictive solution of the damped wave equation when designing the rod string. Since loads calculated that way very accurately imitate actual loads the most important limitation of previous rod string design procedures is eliminated. Strings designed using the proposed model, therefore, have a much enhanced safety against fatigue failures as compared to previous designs.

(2014024) UTILIZING NATURAL GAS AS A FUEL SOURCE IN HYDRAULIC FRACTRUING OPERATIONS

In hydraulic fracturing operations, a large fleet of equipment is required to blend and pump fluid down a wellbore to fracture a formation. High horsepower diesel pumps create the force needed to induce fractures within the wellbore, and in the process, can consume 6,000-8,000 gallons of diesel fuel each day.


 


In an effort to reduce this consumption, Baker Hughes recently introduced the Rhino biofuel hydraulic fracturing pump which allows for up to 65% replacement if its diesel consumption with natural gas during pumping operations. Biofuel systems present several significant advantages such as no loss of horsepower, improved emissions, reduced diesel consumption, and the utilization of natural gas as a fuel without utilizing a spark-ignited natural gas engine.


 


With more stringent emission requirements being set forth by the Environmental Protection Agency, it is beneficial to have the ability to reduce operating costs and engine emissions by using cheaper, cleaner natural gas.

(2014026) VORTEX TOOLS: KEEPING OIL PRODUCTION TANKS IN COMPLIANCE WITH EPA

When installed in the liquid leg of the separator, Vortex Tools spin and entrain harmful hydrocarbon vapors from the gas, thereby increasing the oil recovery. By doing so, operators remaining compliance with EPA air quality emissions while recovering additional oil condensate and natural gas liquid values (NGLs). Increased oil recovery, reducing BS&W and cheaper gas are the results of this patented process.


 


Tested in E Texas wells at 103-degree F ambient daytime temperatures, all production tanks were in air compliance with Vortex (especially important as the number of wells-per-pad has increased while air quality standards remain the same). These patented Vortex tools use no additional energy source, have no additional carbon footprint, and no moving parts/maintenance.

(2014027) DEALING WITH EPA QUAD O

A new federal air quality rule governing midstream and upstream activity is in effect.  The rule, also known by its more formal citation 40 CFR Part 60 Subpart OOOO, or ‘New Source Performance Standards (NSPS) Subpart Quad O’ contains new regulations and revisions to existing statutes. This rule will have a major impact on how the Oil and Gas industry has been operating regarding waste gas emissions.  Reverberations will be felt across the industry by these more stringent rules governing upstream exploration and production segment as well as the midstream segment. The rule addresses fracking, compressors and production emissions but the largest source of waste emissions will be generated by storage vessels.  According to World Oil’s estimate of  producing wells, based on surveys of state agencies and company sources, indicates there are over 536,000 oil producing wells and 485,000 gas producing  wells. A very conservative estimate would be about approximately 650,000 crude oil, produced water and condensate storage tanks in the United States and is increasing. Any new Oil and Gas storage tank will be regulated by NSPS Quad O if emissions of VOC’s are more than 6 tons per year. According to the regulation they must reduce emission by 95% through recovery or combustion to be in compliance. Change is in the air.

(2014031)LONG TERM SCALE INHIBITION USING A SOLID INHIBITOR APPLIED DURING HYDRAULIC STIMULATION IN THE PERMIAN BASIN WOLFBERRY

Long term scale inhibition and economic enhancement is a desired outcome for oil and gas operators. The completion phase of a well involves hydraulic fracturing, which involves the introduction of a mixture of water and specially engineered chemicals pumped at high pressures and rates to achieve a fracture into a low permeable formation. Due to these mix waters, pressure, fluctuations, and temperature variations form the fracturing operation, liquid scale inhibition chemicals are typically pumped 'on the fly' throughout the fracturing treatment. Typically, these chemicals deplete within months after the fracturing operation and the need for continuous intervention from a chemical service company is then required to inhibit any scale potential as the well produces. This study evaluates a wolfberry trend field and compares conventional liquid scale inhibitors versus solid inhibitors over a selection of over 300 wells. This study demonstrates the effectiveness of scale inhibition, longevity, and the economic impact.

Therefore, building large, elaborate wireless communications networks with a single technology was a way a company might demonstrate its decision-makers to consider better manageability, expandability, cost and speed. By integrating various types of telemetry technologies together, it can offer significant benefits that are easily and cost-effectively incorporated into one cohesive data communications network.


 


Collecting data from multiple locations and delivering it over a widespread area can create challenges that no one technology can overcome alone. Hybrid communications networks can incorporate carious technologies and address key factors such as data security, network speeds, infrastructure costs and on-going costs to meet your specific network objectives.

(2014035) MAKING PRODUCED WATER WORK: IMPROVED ELECTROCOAGULATION DESIGN FOR PRACTICAL SUCCESS IN THE OIL FIELD

It has become increasingly attractive and necessary to reuse treated produced water for frac fluids, especially in remote locations or limited water sources regions to minimize freshwater usage. Eletrocoagulation (EC), a traditional water remediation technology, was recently introduced to oilfield application. However, the complicated components in produced water are challenging for traditional EC systems.


 


A new EC apparatus has exhibited cost-efficient remediation of produced water, especially in the removal of iron and suspended solids that have restricted concentration for making frac fluids. The unique EC system has demonstrated fast reduction in iron from over 900 ppm to less than 5 ppm from high-concentration oil contained water, and efficient removal of hydrogen sulfides (H2S), heavy metals, bacteria, and other contaminants. The system has been successfully used for treating produced water for numerous operators in the Permian Basin, reducing operating costs more than 20% while reducing freshwater demand and trucking over 90%.

(2014036) WATER TREATMENT SOLUTION

Water management is one of the largest expenses associated with the production of oil and gas (O&G) resources. Water recycling and reuse can save time, costs, and resources for exploration and production (E&P) companies resulting in enhanced operating efficiencies and improved bottom line results.


 


Electrocoagulaon (EC) is a technology based on proven scientific principles of electro-chemistry and successfully used in the water treatment industry for many years.  Recently, EC has grown rapidly as an effective and economical method for treating water in the O&G industry. The use of EC is a proven method for treating produced and flowback water or reuse in production activities or subsequent frac jobs.  Savings are generated from reducing costs associated with fresh water sales, water transport, and disposal. Compared to traditional treatments utilized to remove residual oil and suspended solids, EC delivers lower operating costs using less labor and smaller footprint.

(2014039) A FOUR STEP APPROACH TO VERIFY DELIVERED PROPPANT

Since the late 1940's, proppants have been the primary construction material for a conductive hydraulic fracture.  However, it was not until the late 1970's that critical properties were indentified and performance examined under guidance from the American Petroleum Institute (API). By the early 1980s SPI proppant testing recommended practices (RP56, 58, & 60) to be applied at the website were scribed and introduced. Yet, employment of these American standard practices at the wellsite became cursory as the rig count collapsed and time passed.  This subsequently left the industry with inconsistent data, lack of accountability, poor record keeping and little information for assessment of delivered proppant. The three API standards have since transitioned to one, RP 19C. This paper illustrates correct application of the standard in a four step approach (test, reference, track, review) to consistently reconciled bargained and delivered proppant.

(2014040) TREATING PRODUCED WATER WITH ELECTROCOAGULATION FOR REUSE IN

High concentrations of total dissolved solids (TDS) are typically problematic in fracture fluid development due to interactions with the buffers and crosslinkers used for waters of higher quality. High hardness and high temperature usually cause loss of viscosity in the fluid; however, proper frac fluid design can successfully keep viscosity and pump the job. This paper will discuss the successful design of a borate crosslink frac fluid design that reuse produced water treated with electrocoagulation (EC). The water in this particular case history had high concentrations of calcium and magnesium with a calculated TDS greater than 250,000 ppm. In the field, oil and iron quantity were changing, although the hardness and TDS remained high. The frac fluid design was able to accommodate the high hardness with little variability in formulation throughout the frac. Different buffers as well as our most concentrated borate crosslinker were able to maintain stability.

(2014042) EXTREME H2S REMEDIATION FOR PRODUCED WATER REUSE IN FRACTURE STIMULATION

Hydrofacturing with 100% recycled water is very desirable in highly sensitive clay formations to mitigate swelling and production impairment. Recycling of produced water can also save operators thousands of dollars per well in fresh water, Trucking, and disposal costs. Yet one obstacle to reuse for many produced waters in the Permian Basin is high hydrogen sulfide (H2S) concentrations.


 


With typical H2S treatments, such as scavengers, chemical and biological oxidation, the cost/bbl is prohibitive on produced water and high H2S levels. A new, more economical H2S remediation techniques addresses such challenges safely and economically. The water is then clarified, creating a low total suspended solids (TSS) solution ready for hydrofractuing.


 


This paper discusses the treatment of 22,000 bbl of high H2S produced water used in the successful completion of an 8-stage continuous slickwater frac in the Ramsey Formation, of the Black River South Field, in Eddy County, NM.

During recent discussions with operating company field and engineering personnel, it was discovered that some companies may not have a failure tracking process nor know the benefits of establishing one. 


 


This paper will provide a summary of prior published industry efforts and include three (3) separate failure reduction studies showing the benefits of failure tracking ranging from over 17 years to a few months of operation.  These studies from three (3) different operators in the Permian Basin showed the benefits of: determining what downhole equipment failed and the cause of the failure, tracking the failure location in the well, and calculating the final reduction in operating costs due to reduced failures and reduced workovers. This paper will also show the additional benefits from keeping good records and knowing the manufacturer of the downhole equipment and/or if the downhole equipment manufacturer was changed.

Analysis and control of reciprocating rod lifted (RRL) wells has changed drastically over the past 20 years.  Advanced diagnostic tools first started appearing on desktop applications, and over time have shifted to the wellsite to provide more accurate control of an RRL system in real-time.  All of these tools depend on a dynamometer card in order to properly analyze and control an RRL system.  However, the inputs to the dynamometer card are often of questionably accuracy.  A poor quality dynamometer card can lead to improper control of the RRL system and inaccurate results from the calculations that depend on the dynamometer data (i.e. rod stress, gearbox torque, structure loading, PIP, etc.).  This paper will discuss the variety of instruments used to capture the inputs to a dynamometer card (polished rod load and position), their strengths and weaknesses, how to recognize errors in the input data, and how to correct it.
