CREW CHECK LEAKAGE
Crew rojok on duty to check leakage string geophones and check the cable link with LT after raised before it is created again on the track. Check leakage is very important to ensure the inclusion geophone crossing in good condition and to reduce the commutation of geophones and cables in the path,making it easier for trouble shooting. Check for leakage geophones using scan strings. Equipment is taken is :Lt set(cable connector),batteries,jumper power,Laul,tool set(nail,tape,glue,clamp pliers,rope),string scan,contack cleaner,multimeter,buckets,drums,tarps,umbrellas,fuel,compressor,radio Ht,work programs,blank toolbox meeting,helmet,shoes,gloves,glasses,nose masks.
- Depth of geophones to be precise.not too far ,ie geophones embedded in clutch so geophones can receive signal properly seismic vibrations.
- Geophones must erect position for geophones to receive sismic with maximal.
- Planting geophones had to be careful so as not cause damage.
- Not good if the geophones planted on the roots,because it can cause noise when the tree roots are swaying in the wing.
A. Normal expanse
B. Stretch of symmetry
C. Stretch Group
- the distance between the trace
- the distance between the trace *the number of geophones per trace.
Because the distance between the trace is 30 meters then the distance between geophones is 28,33 meter/(18-1) or equal to 1.667 meters. Position stretch of geophones aligned with the track so that all the geophones that lie right at the track.

SHOOTER RE-DRILL
Shooter re-drill crew tasked with re-recording due to the occurrence of misfire. In a shooter crew crew there,there was a shooter shooter,shooter must have licenci shooter from migas(oil and gas) crew shooter/re-drill to bring the same equipment with the drilling of production. Equipment brought a set of drilling tools and equipment to other types of flushing like polymergel,explosive,detonator completed,if there are holes for equipment trouble shooting,such as: lost hole,line cut,lost wire,dead after shoot,short wire,dead cap,weak shoot,cap only,no ctb and vht,lost record,wrong spread. Equipment carried: mud pump,king swivel,neple, king hose swivel,drill pipe,suction hose,dragbit,suction hose strainer,lock pipes,hoes, derigen 20 liters, firing line,planting hole,dummy,blaster slave,toolset,lastok,fishing hole,handak box lock padlock,key lock box detonator,dry batteries,cap tester,suction pump gasoline,machetes,pliers jows,polymergel,capsim (uphole test),antenna ringo,radio ht,depth charge,work programs,p3k,blank toolbox meeting,safety equipment (helmet,shoes,groves,glasses,nose masks).
PRODUCTION SHOOTER
Production crew assigned to blow up shooter shot point. Equipment that is brought is the master blaster slave to provide current to blow up the detonator. In one crew,there is one person shooter that already have licences from the oil and gas. Slave blaster is equipped with a radio frequency signal receiver as a communication tool of labo to blow deto,and send data such as holu-up time and confirm to the labo-time break. Crew shooter brings firing line consisting of two lines,that is to be connected to a cable deto and another to be associated with an up hole geophones,crews should bring fishing rod to make it easier to O ring that is planted in the hole Sp. Equipment carried : dry batteries,blaster slave,firing line,antenna ringo,geophone uphole,capsim,toolset,planting hole,fishing hole,radio ht,work programs,P3k, blank toolbox meeting,helmet,glasses,groves, shoes,nose masks.
CREW REPEATER
Repeater crew assigned to install repeater antennas,also set up towers to install antenas. In the area wich is not possible to establish a tower,the antenna can also be mounted in trees. Repeater placement should be considered for facebook to connect the twn sides are communicating. Altitude repeater should also be higher than the surrounding location. Equipment carried are repeater antenna,radio repeater,tali labrang,connector,spare jumper connector,antenna cables,ground nails,ground cable,batteries,jumper power,harnes,toolset(contact cleaner keys),radio ht,work programs,P3k, blank toolbox meeting,helmet,groves,shoes,glasses,nose masks.
CREW BATTERIES
Batteries crew assigned to install thet batteries on Laul or Laux on the track one crew assigned to install one battery and is led by a foreman phone. One crew brought two strings of space rolls of geophones and one link cable. In addition to installing cable,telephone foreman crew is also tasked to perform trouble shooting and keep the noise on the track.
STRETCHER CABLE AND PLANTING GEOPHONES
Stretcher cable is the first phase of work on recording. streched cables carried by the landscape crew. A landscape crew bring 8 rolls link cable and 32 geophones. Duty crew spans connecting cables and geophones are well in accordance. A landscape crew usually carry a roll cable link or two string geophones. After extending the cable further work is done by planting geophones rojok crew. Equipment needed include super planter to make a hole where the geophones are planted,planting hole to plant geophones,and ropes chaining to measure the distance between geophones to comply with predetermined parameters. It should be noted on the planting of geophones are :- Depth of geophones to be precise.not too far ,ie geophones embedded in clutch so geophones can receive signal properly seismic vibrations.
- Geophones must erect position for geophones to receive sismic with maximal.
- Planting geophones had to be careful so as not cause damage.
- Not good if the geophones planted on the roots,because it can cause noise when the tree roots are swaying in the wing.
TYPE EXPANSE
Type expanse consists of :A. Normal expanse
B. Stretch of symmetry
C. Stretch Group
A. NORMAL EXPANSE
In a sring of geophones or a trace there are 18 geophones. In the normal stretch of the distance between geophones first with geophones to-18 is- the distance between the trace
- the distance between the trace *the number of geophones per trace.
Because the distance between the trace is 30 meters then the distance between geophones is 28,33 meter/(18-1) or equal to 1.667 meters. Position stretch of geophones aligned with the track so that all the geophones that lie right at the track.
