Hassi Messaoud (HMD) field location
Hassi Messaoud (HMD), one of the largest mature fields in the world is located in the Algerian Sahara Desert, 800 km
south of Algiers.
HMD Reservoirs
The main reservoir is the Cambrian sandstone and second target the Quartzites of Hamra. Cambrian
sandstone forms a flattened anticline. The production comes from D1, ID, D2, D3, D4, D5 and upper part of
R2. The maximum thickness of producing layers is 200 m but due to Hercynian erosion (which can reach top
of ID) this thickness, in some parts of the reservoir, is reduced by half, the location of which is difficult to
predict due to lack of resolution of the seismic data.
HMD Current production & Objectives
HMD field was discovered in 1957 and put on production in 1958. Since more than1500 wells have been drilled from which
today: about 1120 producers (natural flow, gas lift and so called “fermés - about 300 wells mainly affected by sever gas or
water breakthroughs), 120 Gas injectors, 60 water injectors, 100 dry and unexploitable and about 90 abandoned.
Maintain and Increase the production in HMD
region fields is the objective of Sonatrach DP
HMD.
To achieve this objective, DP is also working with
the main services companies. The join team
Sonatrach DP – Schlumberger called TAO
(Technical Assistance on Operations) is based in our
office in HMD and working in daily basis with our
engineers with the moto:
“one team, one objective”.

Production Enhancement Interventions
Heterogeneity of the reservoir, combined with sever Flow Assurance issues make the exploitation of HMD
field very challenging requiring a well by well analysis for any production enhancement interventions.
Depending on the issue the recommendations can be: Core from the well MD 340
 Matrix treatment (Clean out, Reformat, Acid)
 Perforations
 Hydraulic fracturing
 Multistage Fracturing Completion
 Short Radius re-entry
 ESP installation and Gas lift optimization
 Well tests (Build up, PFS, Vx…), PLT, FSI, RST

Matrix treatment operations
TAO Tasks:
 Selection of well candidate for Matrix treatment
 Preparation of the execution program, job procedure
 Follow up the execution
 The frequent CT operations in HMD field are:
 Water Shut off
 TubeClean with JetBlaster  Set Plug
 ScaleBlaster  Velocity String
 Clean Out  Fishing
 Nitrogen Kick Off  ACTivecasing patch for Gas shut off
 Reformat Treatment  ACTivefor run FSI Logging
 Mud Acid Treatment  Logging with E-line
 MudClean  ACTiverun CoilFLATE (Inflatable
 CleanSWEEP
packer)
