Injector apparatus and method of use

An injector comprising:

• a first stroke unit comprising:
• a first gripping member that removably binds an outer circumferential surface of an elongated round flexible member,
• a first actuator engaged with the first gripping member in a manner that allows the first gripping member to bind or release the elongated round flexible member, and
• a first reciprocator for translating the first gripping member, wherein said translating causes the elongated round flexible member to translate when the first gripping member binds the elongated round flexible member, and wherein said translating causes the first gripping member to reset when the first gripping member releases the elongated round flexible member;
• and
• a second stroke unit comprising:
• a second gripping member that removably binds the outer circumferential surface of the elongated round flexible member,
• a second actuator engaged with the second gripping member in a manner that allows the second gripping member to bind or release the elongated round flexible member, and
• a second reciprocator for translating the second gripping member, wherein said translating causes the elongated round flexible member to translate when the second gripping member binds the elongated round flexible member, and wherein said translating causes the second gripping member to reset when the second gripping member releases the elongated round flexible member.

An injector for translating an elongated round flexible member relative to a wellbore, the injector comprising:

• a stroke unit comprising:
• a plurality of gripping members, wherein each of the plurality of gripping members removably binds the outer surface of an elongated round flexible member,
• at least one actuator engaged with the plurality of gripping members in a manner that allows the plurality of gripping members to bind or release the elongated round flexible member, and
• at least one reciprocator for translating the plurality of gripping members, wherein said translating causes the elongated round flexible member to translate when the plurality of gripping members bind the outer surface of the elongated round flexible member, and wherein said translating causes the plurality of gripping members to reset when the plurality of gripping members release the outer surface of the elongated round flexible member;
• and
• an outer housing in surrounding relation to the stroke unit for containing pressure from the wellbore.
