This paper (SPE 50964) was revised for publication from paper SPE 29266, first presented at the 1995 SPE Asia Pacific Oil and Gas Conference held in Kuala Lumpur, 20-22 April. Original manuscript received for review 4 May 1995. Revised manuscript received 31 March 1998. Paper peer approved 19 May 1998. Summary A laboratory and field study directed at improved well performance of horizontal wells is discussed. During the study, several wells were matrix acidized by use of bullhead and coiled tubing (CT) placement techniques in carbonate reservoirs. The study indicates that acid placed with CT diverted with foam, or a temporarily crosslinked gelled acid (TCGA) system, provides excellent zone coverage and damage removal. Conventional bullhead techniques do not result in effective damage removal. The study emphasizes the evaluation of the treatment results and the development of improved acidizing techniques. Computer simulations of matrix acidizing indicate that proper placement techniques are essential. This observation is supported by field data in wells completed in carbonate reservoirs. The keys to successful damage removal are the placement of acid through CT and proper diversion. Producing-logging and well-performance data support this claim. The proposed treatment is applicable in both horizontal and vertical wells completed in carbonate reservoirs. P. 147

In this paper, a new carbonate stimulation methodology and its impact to the planning of very long, open hole completions will be presented. While the key objective of stimulation is to connect the well to the reservoir, completion equipment design and related well performance have become more important factors. Traditional methods of stimulation modeling and fluid placement are no longer sufficient for these types of wells. This paper introduces how completion design becomes more complex for more aggressive stimulations. For example, completions with pre-drilled or slotted liners for stimulation with coil tubing acid wash are less sophisticated than ball drop liners for high-volume acidizing or fracturing. In long horizontal completions, computer modeling of stimulation needs to address the flow conditions caused by liners, swell packers and inflow control devices (ICDs). Recent well planning for a long horizontal pilot well (Pilot Well 5) has included the use of new carbonate matrix stimulation software to design a fit-for-purpose completion liner that will accommodate bullhead treatment of a long completion interval. Various completion designs were considered based on objectives from reservoir engineering and geology. Being part of a pilot well program, the strategy is to test fit-for-purpose liners that would balance completion cost with long term productivity and recovery. The well design required more than 100 runs of the new carbonate matrix acidization software to finalize a liner design that employs over 200 holes distributed along the length of the lateral. The final design was developed to accommodate uncertainties in the reservoir properties and allow for safe and reliable rig operations. The resulting design could serve as a lower-cost alternative to ball drop stimulation liners for long openhole completions.
