SERVING THE OIL AND GAS INDUSTRY SINCE 1989

Slide 2

What's new in Polymer Technology? New instruments to help get the most oil & gas from your wells.

Slide 3

Polymer Services, LLC Expertise: Design, field application, and assessment of polymer gel medications since 1989. Privately possessed and worked. Administration and representatives are all locals of the prompt zone. Administrations: Assistance with applicant determination and treatment plan, polymer items, lab, field execution gear and experienced teams and venture supervision. Central station and Field Offices: Plainville, Kansas, USA.

Slide 4

General Overview lately, POLYMER SERVICES has pumped a sum of 2,005,805 barrels of gel in 782 medications. (as of March 1, 2010) Approximately 1500 prior medicines were pumped (1989-2002) utilizing more established advances. It is evaluated the medications have yielded no less than 3,500,000 barrels of extra oil to date. Normal incremental oil creation per well is 4475 bbls, including unsuccessful medications. Shows a gross estimation of at any rate $175,000,000.00 (in light of $50/bbl oil)

Slide 5

What is Polymer Gel? The first procedure developed(1960's), by Phillips Petroleum Company as an approach to lessen water generation in the Bemis-Shutts field of Kansas (chrome/redox framework) The primary polymer treatment ever pumped anyplace on the planet, was by Phillips Petroleum Company in the Bemis-Shutts Field in Ellis County, Kansas in the late 1960s, under a lot of mystery. Today's gels are made when polymer is blended in water and cross connected with a trivalent chromium particle. The innovation has advanced from early biopolymers to present day engineered gels which are currently utilized around the world.

Slide 6

Polymer and crosslinker are blended at first glance instead of past frameworks that (ideally) blended in the supply. This was known as in-situ gellation. Gel Strength is a component of polymer fixation. Gels having consistency marginally more prominent than crisp water to that of elastic can be made in for all intents and purposes any water, at temperatures up to 270  F, in high TDS, H2S and CO² situations. Proceeded:

Slide 7

Used to close off undesirable water in creating oil and gas wells, and to enhance conformance at water/CO² infusion wells. Thought to be perpetual after position. Unique hardware is typically required to legitimately mix and pump polymer gels.

Slide 8

Modern Chemistry Options The ebb and flow framework utilized is an altered tri-chrome framework known as WATERBLOCK, in view of innovation initially created by Phillips Petroleum Company, and is generally in charge of the ebb and flow high achievement rate in the Arbuckle dolomite and different developments in Kansas. The way to current victories is the utilization of this chromium III gel framework rather than more seasoned crosslinking innovations, which were less powerful or excusing than the momentum framework.

Slide 9

What are the advantages? This science was initially produced for stable gels in more profound more sweltering wells than we typically find in Kansas. It was additionally expected for "unfriendly" situations, which incorporate significantly higher salinities, high H2S checks, high TDS brackish waters, and so on. Polymer Services has changed this science to likewise be exceptionally powerful in shallow low temperature wells. An advantage to this science is more prominent last gel quality and less issues with polymer generation when the well is walked out on, and more prominent long haul gel security in our "moderately agreeable" wells.

Slide 10

What else do we do any other way? POLYMER SERVICES utilizes "Fluid Polymer" which is specially mixed as a "pre-wetted" arrangement, rather than the dry powder utilized as a part of other basic procedures. Pre-wetted arrangement implies every individual polymer grain is pre-hydrated in it's own water bead, then suspended in a mineral oil arrangement. This permits the polymer to hydrate a great deal more quickly for a more total and powerful crosslink, even at lower temperatures.

Slide 11

How does this offer assistance? A pre-wetted polymer arrangement is considerably less demanding to completely hydrate and totally break down in various types, hardness and temperatures of blend water. Better disintegration implies more total cross-connecting, better last gel quality and dependability, and no delivered polymer when the well is re-begun.

Slide 12

How have Polymer employments today enhanced contrasted with what has been done before? Today's gels are more steady in an extensive variety of pH, high temperature, high H ²S, saltiness and high TDS situations. Today's medications are substantially bigger in volume, which takes into consideration more profound infiltration into the repository, in this manner yielding fundamentally more noteworthy measures of incremental oil and longer compelling treatment life.

Slide 13

Well competitor determination criteria Significant staying portable hydrocarbons set up (aggregate generation history is normally a decent sign). Wells creating at or close to their financial constrain because of costs related with over the top water generation. High water transfer or potentially lifting costs. Makers in characteristic waterdrive stores. Proceeded:

Slide 14

Well hopeful choice criteria Producers in water surges are treatable, yet prescribe treating injectors. Here and there both the infusion well and culpable makers are dealt with for ideal outcomes. Better shot of expanding oil generation when treating wells that have high delivering liquid levels. High porousness differentiate amongst oil and water soaked shake Vuggy and additionally normally cracked store.

Slide 15

Example of High Permeability differentiate Arbuckle center recouped in Rooks County, Kansas amid a developing operation on a workover fix.

Slide 17

Key Factors in outlining gel medicines The sort of gel polymer/crosslinker and focus Treatment volume Treating methodology

Slide 18

Treatment Design Information Wellbore schematic/information Tubing size & profundity, packaging size & profundity, punctured/openhole profundities, shaft or submersible pump, and so forth. Porosity/electric logs Core reports Oil and Water generation history Fluid pump-in information from corrosive employments or other work Cumulative recuperation delineate/isopach outline cost and water taking care of cost

Slide 19

Sizing the Treatment DISTANCE… Radial or direct stream count 50-1000 Bbls. Per porosity-foot (relies on upon well profitability) VOLUME… Estimate day by day limit of well to deliver liquid at most extreme draw-down, then utilize that volume to decide least gel treatment volume Need static and creating FL, and delivering rate(s)

Slide 23

Before Pumping the Job Ensure that the wellbore is perfect, sand pump or generally get out well to unique TD. An AGGRESSIVE corrosive cleanup treatment has turned out to be exceptionally successful ( 1500-3000 gallons 15% NEFE, pump away with water at high rate). Set up a greatest treating weight. Utilize ascertained frac angle for field or run step-rate test if important. Proceeded:

Slide 24

Before Pumping the Job Select a satisfactory wellspring of water that will be utilized to mix and pump the treatment (new. Kcl, or clean delivered water which has been tried for polymer similarity before treatment). Select a polymer-good biocide for blend water (blend at focus suggested by the provider). Set packer on tubing to disengage zone to be dealt with.

White Eagle Resources On June 2, 2003, a 10 well venture was initiated In the Bemis-Shutts field for White Eagle Resources. Before treatment, the subject wells created a consolidated normal of 47 BOPD and 12,000 BWPD.

Slide 34

Overview of the White Eagle medicines Treatment sizes extended from 1100 barrels to 5100 barrels of gel, contingent upon the weight reaction amid treatment. An aggregate of 38,320 barrels of gel were pumped on the 10 well venture. Weight reaction went from vacuum to a most extreme of 750 psi surface weight.

Slide 35

White Eagle Results Individual well preparations after treatment extended from 16 BOPD to 145 BOPD, on a normal of close to 150 BPD add up to liquid. Top generation happened toward the beginning of October, at a little more than 500 BOPD. Current generation is 180-200 BOPD.
