(2014032) RADIO PATH STUDIES 101

The use of computer-generated software to predict radio frequency (RF) path studies has been around for several years. Combined with the latest GPS and Google map data, you can determine how well your network will work, its RF path link reliability, link budgets, Fresnel zones, multi-path and if you mat need to invest in different towers, use more repeater or add additional technologies to try to cover the area you need for data communications. By examining the guidelines and some fairly simple explanations of how to get the correct information, attendees can discover the true benefits of this software. Topics include a look into radio signal path loss -- a particularly important element in the design of any radio communications system or wireless system, predicting the signal path loss, free space path loss basics, link budget antenna gain and the effect of multipath propagation to achieve maximum throughput and reliability.

(2014033) LEVERAGING HYBRID NETWORKS SYSTEMS TO YOUR ADVANTAGE

Organizations with geographically dispersed assets in the field, such as those in the oil and gas industry, would typically select one technology, one source, or one vendor to collect, retrieve and report critical data. 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.

(2014038) WELLSITE CEMENTING QUALITY CONTROL - A NECESSARY PRACTICE FOR CEMENTING SUCCESS

Cementing has been an important part of wellbore isolation and stability for decades.  Cementing, though, if not implemented properly can also be costly, resulting in wrong densities, incorrect displacement, flowback, micro annulus, etc. However, these issues can be avoided with experienced quality control practices. This paper outlines a practical approach to cementing quality control to ensure that the operator has the best opportunity to achieve successful cement mixing and displacement. Case histories are presented to demonstrate the importance of these quality control practices.

(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.

(2014041) YOUR TUBULAR STRING- KNOW ITS FIT FOR SERVICE WITH NDT TECHNIQUES

In all successful tubular management programs NDT is used to know the real condition of pipe proposed for projects and to gain knowledge of used tubing at the well site. There are several testing methods available such as electromagnetic, ultrasonic, magnetic partible, eddy current and gamma-ray applied to various testing apparatus. There is an assumption made every day about new tubular production are defect free so know your material and its source, inspected until a failure occurs. in many mays nondestructive testing is applied to help show the condition  of new tubular products and to provide guidance on used tubing while pulling and in facilities for reclamation. NDT is directly associated to positive economics through extending the mean time between failures.

(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.

(2014044) WELL AND FIELD CONTINUOUS IMPROVEMENT – THE VALUE OF FAILURE TRACKING

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.

(2015001) ACCURATE LOAD & POSITION MEASUREMENT IS CRITICAL TO QUALITY DYNAMOMETER ANALYSIS

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.

Pumps are the heart of a rod pump system, but as operators, how much do you know about the pumps that are being run into your wells and how they are being repaired.  This paper will briefly describe pump repair procedures, best practices that the shop should be following, and a pump shop inspection report that helps identify if those procedures are being followed. It will cover what pump failure data should be captured, why it is important, and what type of information may be available in report form. Many operators do not realize that you can gain valuable well and operational data from a pump report besides what is needed to optimize the pump alone. It will also explain how the operator should get involved in the decisions that affect the pump design and repair which can affect costs and run life.

(2015003) FLUID EXTRACTION

Fluid Extraction Technology can improve down hole gas separation by employing material and fluid flow properties in ways that are not now effectively utilized.  Downhole pumps that handle fluids are adversely affected by free and entrained gas entering the inlet of the pump.  To separate the gas ahead of the suction of pumps in the bottom of a well, operators typically configure a path for the fluid to be redirected downward to allow the gas to rise while the liquid falls to the intake of the pump.  Virtually all of the gas separators use single pass serial separators based on gravity.  The primary separation is typically the tubing by casing annulus and the second stage of separation is the labyrinth of falling liquid and rising gas inside the mud anchor or packer assembly.  This technology can be very effective but often times is not sufficient.  In addition, the size and length of the equipment has a larger material footprint than necessary.


 


Fluid Extraction technology uses gravity but also uses mechanical and fluid properties to enhance separation.  These attributes include wettability, fluid adhesion, gas nucleation and the concept of Liquid hold up or circulation cells.  Integrating these concepts allows better use of the primary flow volume of the casing by tubing annulus.

(2015007) FROM FAILURE TO SUCCESS: A METALLURGICAL STORY ON SUCKER ROD PUMP BARRELS

Sucker rod pumping applications are the oldest and most widely used means of artificial lift for oil wells. The pumping performance and the longevity of the pumping systems with their corresponding pump parts have improved significantly throughout the years, but the failures remain inevitable. These failures are costly and time consuming for operators, but analyzing those enables us to improve the part design and the decision process of part selection for certain well conditions, and minimize future failures.


 


This paper focuses on pump barrel selection and operation with regards to base metallurgies coupled with various plating processes. It aims to inform the reader of common pump barrel failures and their causes, along with educating operators about available barrel types and their optimum operating environments.

(2015011) IMPROVING ARTIFICIAL LIFT STRATEGIES IN YESO HORIZONTAL WELLS

Many operators in the Permian Basin have moved from drilling vertically to developing leases with horizontal drilling.  After implementing a horizontal drilling program, three critical challenges emerge:  1) selecting the most efficient means of initial production; 2) using a rod pump design without experiencing gas interference or losses in volumes; and 3) handling a horizontal well at pumped-off conditions.  Drawing the well down as quickly as possible is ideal for generating the best economics. The initial investment and operating costs of the artificial lift system must also be considered when performing economic analysis.  Rod pumping horizontal wells to produce the high rates that the model describes is challenged by gas interference which has resulted in the following: rod and tubing wear, upper buckling tendencies, increased man hours trying to resolve problems, and a loss in production.  When pumped off conditions occur while rod pumping from the kick off point, a noticeable decline in production can be observed.  In low pressure reservoirs, lowering the pump into the curve can prove to restore or even increase production rates.  By studying past cases of producing Yeso horizontal wells in the New Mexico Shelf Platform, COG has been able to select an optimally sized ESP, smoothly convert to a rod pumping system to achieve pumped off conditions, and continue to produce in the curve to avoid losses in production.
