• LUIS DIAZ: PROFESSIONAL PETROLEUM ENGINEER WITH OVER 35 YEARS IN THE OIL AND GAS INDUSTRY.

LEADER FOR TEAMS RESPONSIBLE FOR DRILLING, PRODUCTION AND WORKOVER FOR SEVERAL MAJOR OIL

COMPANIES. GIVEN THE OPPORTUNITY TO USE STATE OF THE ART TECHNOLOGY.

• JESSE HERNANDEZ: ARTIFICIAL LIFT ENGINEER WITH 35 YEARS IN ARTIFICIAL LIFT AND SUPPORT OF NEW

TECHNOLOGY IN COUNTRIES ALL AROUND THE WORLD.

35 YEARS OF MAKING HYDRAULIC LIFT SYSTEMS WORK

THE BEGINNING: THE SEARCH FOR ECONOMICS IN RE-ENTRY OF MATURE OIL FIELDSThe search for an economical solution to

recovery of an estimated 300,000 barrels of oil

from a field that has been produced for over

100 years.

Studies indicated the need for re-entry .

Slim hole directional drilling provided the

economics, but a lift method was needed.

Hydraulic power transmission offers

advantages including RIGLESS installation

INDUSTRY RECOGNIZED ADVANTAGES OF HYDRAULIC LIFT

• HIGHER RATE IN REDUCED BORE WELLS

• TOLERANT TO SAND

• ECONOMICS IN MULTIPLE WELLS

• EXCELLENT FOR SEVERE DOG LEGS, DEVIATION OR

HORIZONTAL WELLS

• APPLICABLE IN GASSY WELLS

• LARGE PRODUCTION RANGE

• NO MOVING PARTS

• LOW PRESSURE RESERVOIRS

• RIGLESS INSTALLATION

• RIGLESS PUMP RECOVERY

• FACILITATES TREATMENT FOR CORROSION, HEAVY

OIL, PARAFFIN AND SCALE

DIRECTIONAL, HORIZONTAL OF SEVERE DOG LEGS

GREATER PRODUCTION IN REDUCED BORE RE-ENTRY OR NEW DRILLING

LOWER CAPEX AND OPEX IN MULTIPLE WELL PADS

HIGH VOLUME FLOW BACK OR GASSY LOW PRESSURE OIL WELLS

TOLERATES SAND, CORROSION AND GAS

MOST COMMON REPORTED DISADVANTAGES

• HIGH OPEX - SURFACE MAINTENANCE COST (PLUNGER PUMP VALVES AND PLUNGER PACKING)

• REQUIRES TRAINING AND PRODUCT KNOWLEDGE

• ISSUES WITH SURFACE HIGH PRESSURE PIPING

• ISSUE WITH COST OF TREATMENT FOR WATER AS POWER FLUID IN PISTON PUMPS

HYDRAULIC LIFT NEEDS

• INTEGRATED ENGINEERING

• PRODUCT KNOWLEDGE

• PRODUCT DEVELOPMENT

HYDRAULIC LIFT IS A PROVEN PRODUCTION TOOL THAT OFFERS SOLUTIONS

WHAT DO WE NEED

•WE NEED TO DEMONSTRATE OPTIMIZATION AND RELIABILITY ON

YOUR EXISTING HYDRAULIC LIFT SYSTEMS

•WE NEED TO DEMONSTRATE DESIGN AND INSTALLATION OF THE

ENGINEERED HYDRAULIC LIFT SOLUTION

THE IDEAL OIL WELL CANDIDATE

•WITH INITIAL FLOW BACK RATES TO 4000 BFPD AND A LONG

TERM SOLUTION AT LESS THAN 100 BFPD IN GEOMETRICALLY

CHALLENGING REDUCED BORE GASSY OIL WELLS.
