2016 S-Con Inc. EMR: 0.76

EMR, experience modifier rate, is a three year history of claims paid by an insurance company over a three year period. The less payout of claims by insurance companies translates to a lower EMR. S-Con’s current, 2016 EMR is 0.76.

Generally Speaking:

  • Excellent: 0.40 –0.75
  • Good: 0.76 –1.00
  • Average to At Risk: 1.01 –1.25
  • At Risk to Adverse Projections: 1.26 –2.00

S-Con Inc.’s 2017 EMR Goal is 0.65 or lower.

The majority of S-Con Inc.’s work is in the midstream natural gas industry. This is the link between the exploration and production of natural gas and the delivery of its components to end-use markets. The midstream industry consists of natural gas gathering, compression, treating, processing, storage, and transportation. The midstream industry is generally characterized by regional competition based on the proximity of gathering systems and processing plants to natural gas producing wells and the proximity of storage facilities to production areas and end-use markets.

S-Con is committed to safety for employees, clients and the general public through training, supervising, and monitoring all employees and sub-contractors on safe behaviors in the field as well as in all shop facilities.

S-Con Awarded 30 GPM Amine Regeneration Plant

S-Con was recently awarded the engineering, design, and fabrication of a 30 GPM Amine Regeneration Plant. The plant, consisting of four (4) modularized skid units, will be installed in Texas as an expansion of an existing Natural Gas Treating Plant. To ensure proper fit-up and spacing, S-Con assembled all skid modules inside its Bryan, Texas Assembly Shop, before shipment to the Field.  All skid instruments and control valves were also Shop tested to insure they were in good working order.

S-CON awarded 60 GPM Amine Regeneration Plant

On June 22, 2016, S-Con was awarded the engineering, design, and fabrication of a 60 GPM Amine Treating Plant including the purchase of a new Amine Contactor. This Amine Regeneration Plant is a new/existing stock unit that will be modified to utilize a BKU type hot oil re-boiler instead of the direct fired unit that was originally built for it. The plant consisting of four (4) modularized skid units will be installed in Texas to act as a Fuel Gas Conditioning Unit, feeding a Gas Turbine. Completion is expected in October, 2016.

S-CON awarded Refrigerated Dewpoint Control Plant modification project

S-Con was recently awarded a project to modify an existing Refrigerated Dewpoint Control Plant with Condensate Stabilization. The Plant Design is being modified to allow processing of 5.8 GPM gas, instead of the 2 GPM Inlet Gas the Plant was originally designed for. Additionally, the original Condensate Stabilization system is being modified to now produce a 200 psig NGL Product that can be sold over truck racks. The Customer has tasked S-Con to reengineer and modify the existing Plant to meet these new operating conditions. Plant modifications include: 1) Inlet Slug Catching; 2) Filtering and conditioning of Slug Liquids; 3) Additional Vapor/Liquid separation capacity; 4) Compression of Stabilizer O/H vapors to the Residue Gas stream; 5) NGL Product Filtering and Storage; and 6) Truck Loading Facilities.

S-Con is designing and fabricating four (4) process skids to be installed as part of the plant modification effort. S-Con Construction moved into the field on June 15, 2015 and is already well into performance of necessary demolition work and site preparation. The Customer has asked for a very aggressive schedule, with a targeted re-commissioning date of October 1, 2015.

What Design Should I Use For My Condensate Stabilizer System?

The installation of condensate stabilizers throughout the various shale plays across America is becoming the new rage for gas liquid processing. First, much of the shale gas being produced is so rich in hydrocarbon liquid that the raw condensate production is literally flooding production and processing facilities. Secondly, the ability to now export crude condensate (as long as it has first been “processed”) has opened brand new markets for the producer. However, there are certain challenges that face each application and which vary on a case-by-case basis, depending on such variables as: 1) Location of the stabilizer to an existing processing facility; 2) Product specifications of the product buyer; 3) Composition of the condensate to be processed; 4) Proximity to pipelines and other infrastructure; 5) Other factors.

Raw condensate, by definition, has the entire gambit of hydrocarbon (and non-hydrocarbon) components contained within the liquid and which compositional breakdown is determined by a wide variety of parameters including pressure and temperature. In order to “stabilize” the condensate and make it into a salable product, the light end components are driven off into the overhead vapor stream, while the heavy end hydrocarbon components exit out the bottom of the stabilizer tower. This all seems simple enough, except when you find out that there are a multitude of specifications that can be required for the condensate product and that you have to do something with the overhead vapor product.

Stabilized condensate may be sold under a variety of specifications, most relating to the vapor pressure of the product. In the last two years, S-Con has designed and built stabilizer systems which delivered the condensate product at 200 psig true vapor pressure, 12 psia RVP, 9 psia RVP and 70 degree API Gravity, respectively. Each of these products was classified as stabilized condensate, but they are all substantially different from the others; the 200 psig TVP product is essentially a heavy NGL product, while the 70 degree API Gravity product is a light crude oil. What kind of bottoms product is produced determines all the other factors that go into the system design, such as: 1) System capacity; 2) Overhead product specifications and disposition; and 3) System design and operating parameters (P&T), among other things.

For example: A given size stabilizer system may be capable of processing 5,000 bpd of raw condensate feed when delivering a 200 psig bottoms product, but may only have a processing capacity of 2,000 bpd if a 70 degree API Gravity product is to be generated. Additionally, in the case of the 200 psig product, less equipment and heat exchange may be required, the system may be operated at higher pressure, and essentially all of the propane and heavier components are recovered in the bottoms product. On the other hand, if a 70 degree API Gravity product is being turned out, additional heat is required for the system, essentially all of the hexane and lighter components are driven overhead, and a NGL product is oftentimes recovered from the overhead stream as it cools.

So, the moral of this story is: Know what is going to be processed and what product specifications will need to be met. If these two constraints are known, S-Con and the Client can work together to deliver a plant that will meet all of the Client’s needs and expectations.

Optimizing Existing Asset Performance To Save Capital and Increase Revenue

Capital budgets have been slashed to the bone, but gas still has to be processed, or risk the potential of having oil production shut in because of flaring regulations. To overcome this dilemma, companies are now reviewing their existing gas treating and processing facilities to determine how they can get more out of them with little or no capital expenditures.

Many of the plants put in over the last several years have been stock, “cookie-cutter” type plants which could be delivered and put in service quickly, which was what was needed at the time. This resulted in numerous plants being installed that were not a good fit for the specific application being addressed, thus oftentimes leaving the operator with poor product recoveries and higher than desired operating and maintenance costs. Additionally, since there are very limited capital funds to install new plants, the demand for these existing gas plants to increase throughput and recovery levels continues to be a top priority for midstream operating companies.

The most logical answer seems to come in the form of modifying the existing plants with “after-market accessories.” This may include simple things (such as rearranging some piping or changing operating parameters) to adding additional equipment (such as a secondary distillation column or additional refrigeration). The key, in almost every case, is to get more out of what you already have for less money and that is where S-Con can be a tremendous help to our clients. S-Con’s experienced and knowledgeable process engineers work closely with our customers to thoroughly investigate various options and opportunities to enhance plant performance and operation and, once a direction has been agreed upon, then fully develop the solution and implement it into the existing plant design.

Working together, S-Con and its clients can increase the performance and capacity of existing plants.

How S-Con Does More with Less

With the downturn in oil & gas prices and capital budgets being cut back dramatically, S-Con’s Customers are becoming increasingly focused on potential project economics and costs. To that end, many of our Clients are relying on S-Con to perform screening studies, preliminary/conceptual designs, and budgetary estimates prior to approaching their Management with a funding request. By approaching projects in this manner, S-Con is able to work with the Client to develop a plan that will deliver what is required, while developing a cost basis that can be believed. Additionally, it provides both the Client and S-Con the ability to hit the ground running should the project move forward.

Depending on the breadth and scope of the work to be performed in this process, S-Con can quickly provide meaningful information back to the Customer in as little as three (3) days. S-Con’s team of highly skilled Engineers and Designers work together with the Client to develop concepts and layouts that will meet the specific project requirements, with a careful eye on the overall project cost expectations. This close working relationship between S-Con and its Clients typically results in very few surprises and allows the Customer to approach its Management, confident that the job can be done right and within the stated budget.

Wyoming 120 MMSCFD Natural Gas Treating and Processing Facility Start-Up

S-Con personnel successfully completed a three-week trip to Wyoming where they assisted their client with the start-up of a 120 MMSCFD Natural Gas Treating and Processing facility. Despite facing several adverse situations, the S-Con plant met or exceeded all expectations. Once the inlet gas into the plant meets the design volumes and pressures, S-Con will return to the site and aid in final tuning of the plant under full-load conditions. During the team’s time there, Don Deppe and Trey Brown assisted in the tuning of the Hot Oil System, Amine Treating System, and J-T Cryo Plant and Refrigeration System. The Hot Oil and Amine Systems successfully ran under full-load conditions and achieved all operating and design requirements. The client was able to witness the regeneration of the Mol Sieves and, while the plant load was not what was desired, the Refrigeration System was put into operation by implementing an arrangement alternative to the originally design.

Overall, S-Con accomplished its assistance to the client with the new operating conditions, tuning instrumentation and system operation, and on-site, personal operator training. Working with the client’s own highly capable, “Training Squad,” the new Plant Operators quickly adapted into their new jobs and gained a greater understanding of the plant and its operation.

Bakken Flaring Alternatives and Gas Capture 2014

The Bakken Flaring Alternatives and Gas Capture conference was recently attended by S-Con in Denver. The conference was composed of a variety of producers and vendors detailing various ways to reduce or eliminate the flaring of associated gas in North Dakota. The majority of the methods entailed the mechanical refrigeration method of removing NGLs with the remaining natural gas flared. One vendor added a Deethanizer to provide fuel for a generator to power their unit but still sent the remaining natural gas to flare. Only one, in addition to S-Con’s SUPERCOOLTM Process allowed for the total elimination of flaring and that process involved the conversion of the associated gas into anhydrous ammonia. S-Con’s SUPERCOOLTM Process allows for the elimination of all flaring resulting in highly valued LNG and NGL hydrocarbon products. Please see the Flare Gas Recovery / SUPERCOOLTM page for further details on this superior process.
