New generation Polymer-filled and jacketed wireline cased hole cables eliminate all inherent bottlenecks of traditional wireline logging cables, enabling unprecedented operational efficiency with substantial reduction of well control risk and costly maintenance. This Technology enables a Mexico operator to deliver all their Operator Field wells ahead of time, without any HSE or well control incident while gaining 9 days of early production.

Recently developed Polymer encapsulation and bonding technology completely seal Wireline cables electrical core and armors. The result is elimination of armor birdcaging (see glossary) and stranding, grease injection and associated equipment, cable gassing-up and well fluid related armor corrosion. Total armor torque balance and polymer outer jacket substantially reduce Chrome or glass coated completions damage, cable friction and maintenance requirements. The result is unprecedented well control safety, grease related environmental and reservoir damage elimination, higher operational efficiency with faster rig-up/down and tripping speeds, reduced tractor conveyance needs with improved well access in complex completions and proven early production gains.

Contrary to conventional Wireline cables, the new generation polymer encapsulated cables come with a gas blocked core and a pressure balanced sealed cable termination. Potential well fluid migration through the cable cross section is thus completely prevented. Along with the polymer jacketing, well control risk is all but eliminated. During 2018, and for the first time in Mexico, 45 cased hole interventions, 130 descents and more than 1,000,000 feet in the well polymer cable deployments were carried in a North Mexico gas field. All Perforations, Production logging and other cased hole descents were completed totally free from HSE, operational or well control issues. Logistically challenging cable maintenance trips were all but eliminated, saving substantial time and cost to all parties involved. Compared to conventional wireline operations, time saved using polymer encapsulated Wireline cables represented a 50% reduction in rig-up and rig-down time, as well as 40% operational efficiency gain. With wells delivered early to production all contractual targets were exceeded, adding 9 days of additional production of gas and condensate.

New generation Polymer encapsulated wireline cased hole cables have enabled the Mexico Operator plan and carry out efficient, safe, cost effective, and environmentally friendly Wireline Cased Hole operations, delivering producing wells ahead of time and exceeding contractual requirements.
