Disposal /Trucking Costs From a recent survey of disposal costs in the Permian Basin and Kansas Trucking costs have doubled in the past 3 years Disposal Fees/Maintenance fees have increased 35-50% Total costs of trucking and disposal range from $1.50-$2.25 per barrel, up from.65$ to 1.00$ per barrel. That represents a cost of.036$ to.054$ PER GALLON. Remember these figures! We are enjoying nice returns from the price of oil and gas; are we ignoring our lifting costs that we use to watch so carefully? Why not increase our return by doing some best practices to reduce our water handling and lifting costs?

Produced Water in the Barnett Shale Play: Potential for Beneficial Use It is estimated that more than 5 million gallons of water per well are used in fracturing operations. Most then goes to re-injection disposal. More than 50% of this brine can be re-used in subsequent well fracs. As much as 24% can be recovered as fresh water for beneficial use.
Barnett Shale Water Conservation and Management Committee - 2006 About the Committee Goals A consortium of industry leaders Approximately 20 Energy Companies operating in the Barnett Shale Initiated March 2006 Completed Charter, spring 2006 Status: Collecting information on industry water use Review of Reuse/Recycle Technologies
Chemical Treating Costs have doubled in the last 4 years Due to oil based solvent chemicals Need for careful evaluation of chemical needs-what are the problems-corrosion (downhole, internal, external, surface, etc)-paraffin? What is the best solution-chemical or metalurgy? Small Producers do not have the expertise or the staffs rely on vendors-workshops Good Reference on Proven Chemical Treating Practices are found in a PTTC Developed Produced Water Manual- Looking at Updated and make more comphrensive for small guys-for EXAMPLE A FEW GUIDELINES ARE:
GENERAL GUIDELINES AND PRACTICES FOR TREATING CORROSION BATCH TREAMENT WELLS MAKING <600BFPD CONTINUOUS TREATMENT > 600BFPD ALWAYS SELECT AN INHIBITOR THAT PASSES BOTH AN EMULSION TENDENCY TEST AND A FILM PERSITENCY TEST VOLUME OF CHEMICAL USUALLY BASED ON 100 BFPD Chemical concentrations vary by operator from 1-4 gals per 100 BFPD Rule of thumb: 25-50 ppm concentration is adequate. Excessive volumes can increase oil carryover.
CHEMICAL INHIBITION GUIDELINES CONTINUED FLUSH VERY IMPORTANT OIL IS BEST KEEP OXYGEN OUT PREWET CASING-1 BARREL OF FLUSH PUMP INHIBITOR FLUSH WITH ½ BARREL/1000 FEET-2 BBL MIN. IF FLUSHING WITH H20 USE WATER FROM GAS BLANKETED TANKS OR O2 SCAVENGER
CHEMICAL GUIDELINES CONTINUED PRETREATING RODS 5 GALS INHIBITOR IN TUBING PRIOR TO RUNNING THE PUMP CIRCULATE ONE TUBING VOL PRIOR TO PUMPING UNDER DIFFICULT CIRCUMSTANCES DISPLACE TUBING WITH LEASE CRUDE PLUS 10 GALS OF INHIBITOR LUBRICATE SUCKER ROD PINS

Specifications Maximum operating temperature is 160 0 F (71 0 C) in oil production and 180 0 F (82 0 C) in aqueous service. Coated couplings protect J-area against corrosion. Minimum API torque recommended for tubing connection make-up. No special position make-up or coupling inserts required. Maximum operating temperature is 210 0 F (99 0 C), and increased resistance to CO 2. Coated couplings protect J-area against corrosion. Minimum API torque recommended for tubing connection make-up. No special position make-up or coupling inserts required.
NEW Product Falcon Ultratube TM is a new liner composed of an engineering thermoplastic that can withstand downhole temperatures exceeding 350ºF (177ºC). This patent pending product is highly abrasion and chemical resistant. The mechanically bonded seamless tube is tolerant to minor surface damage and the base resin has been proven in other downhole applications for over twenty years.
