Location : East Crescent Field, Logan Co., Oklahoma
Problem Area : Well #2
Well Description: :
Well #2 was producing from the Mississippi formation and from a depth of 5,500 ft. Paraffin deposition occurred down hole in the tubing. Hot oil treatment was required every 30 days in addition to injection of a paraffin inhibitor.
Solution: A TherMel-Kem™ System was installed and a batch treatment of a paraffin compound (MP-416) was applied. Over a three month period, a combination of the TherMelKem™ System and the paraffin compound, no paraffin deposition could be observed.
It was determined an incremental production increase of 1.68 BOPD was obtained.
Location : Polo Field, Nobel Co, Oklahoma
Problem Area : Paraffin deposition and production decrease
This well was producing through tubing at a depth of 5,265 ft and from the Red Fork formation.
RecommendationA TherMel-Kem™ System was installed to determine if an increase in production could be observed.
Solution: The tubing fluid outlet temperature was approximately 72° F. Temperatures out of the unit collector tank averaged 180° F with good sunshine. 7 Vi gallons of MP-416 was circulated for 18 hours and an increase of 3.41 BOPD was observed. The unit remained on the well for 2 Vi months and the chemical treatment was applied during this period.
Location: Coal Co., Oklahoma
Problem Area:Paraffin deposition occurs in the flow line and in the treating vessel.
Well Description: This well produces from the Cromwell formation and from a depth of 6126 ft. The well is produced from a depth of 6126 ft. and from the Cromwell formation. The casing is 5 Vi” and the tubing is 2W’. Temperature of produced fluid to the flow line is 74°F and bottom hole temperature is calculated at 116° F. Hot oil treatment each 60 days was required due to paraffin deposition.
Solution:A TherMel-KemrM System was installed in June 2013. At the time, production was recorded at 2.0 BOPD. Three pounds of EP-51 OS was batch treated. On the 5th day, production increased to 5 BOPD. 210° F was observed on the collector tank and the tubing return fluid was 99° F. For the next 20 days the well produced at a rate of 6.2 BOPD. No treating rank bottoms were observed during the test period and the flow line remained free of paraffin deposition.
Cost to the producer was substantially reduced.
Location: Creek Co., Drumright Oklahoma
Problem Area:Paraffin accumulation on rods and paraffin deposition in the tubing. Hot oil treatment occurs each 90 to 120 days. Production was at a rate of 2.5 BOPD.
Well Description:This well produced from two low pressure pay zones.
Solution:A TherMel-Kem™ System was installed on June 2014 to control paraffin deposition. This problem well uses vacuum on the casing. With the vacuum shut off, our heat and chemical process cleaned the well on paraffin where the well produced. 1.75 BOPD using no vacuum. With the vacuum placed back on the casing without the TherMelKemrM
System, a production increase from 2.5 BOPD to 3.25 BOPD was observed.
A production increase from 2.5 BOPD to 3.25 BOPD was observed.
Location: Pontotoc Co., Oklahoma
Problem Area:Paraffin deposition on pump rods, in the tubing and in a 2″ poly flow line.
Well Description:The well produces 3 BOPD with a flow line pressure of 24 psi. For years, hot oiling down the annular space to remove the paraffin on the rods and in the tubing was required. This procedure created slugs of paraffin that then blocks the flow lines to storage tanks and subsequently creates tank bottoms.
Solution:A TherMel-KemrM System was installed in June 2014. After two weeks ofTherMel-KemrM System heat and EP-51 OS solid chemical the flow line pressure was reduced and the tank bottoms diminished.
The cost saving for the operator was estimated at $300.00 per month.
